occupancy detection dataset

For instance, in the long sensing mode, the sensor can report distances up to 360cm in dark circumstances, but only up to 73cm in bright light28. The authors wish the thank the following people: Cory Mosiman, for his instrumental role in getting the data acquisition system set up; Hannah Blake and Christina Turley, for their help with the data collection procedures; Jasmine Garland, for helping to develop the labeled datasets used in technical validation; the occupants of the six monitored homes, for letting us invade their lives. The sensors are connected to the SBC via a custom designed printed circuit board (PCB), and the SBC provides 3.3 Vdc power to all sensors. Energy and Buildings. The method that prevailed is a hierarchical approach, in which instantaneous occupancy inferences underlie the higher-level inference, according to an auto-regressive logistic regression process. Depending on the data type (P0 or P1), different post-processing steps were performed to standardize the format of the data. Using environmental sensors to collect data for detecting the occupancy state The Previous: Using AI-powered Robots To Help At Winter Olympics 2022. Effect of image resolution on prediction accuracy of the YOLOv5 algorithm. The Pext: Build a Smart Home AI, What kind of Datasets We Need. The setup consisted of 7 sensor nodes and one edge The two homes with just one occupant had the lowest occupancy rates, since there were no overlapping schedules in these cases. Summary of all modalities as collected by the data acquisition system and as available for download. Keywords: occupancy estimation; environmental variables; enclosed spaces; indirect approach Graphical Abstract 1. Technical validation of the audio and images were done in Python with scikit-learn33 version 0.24.1, and YOLOv526 version 3.0. To address this, we propose a tri-perspective view (TPV) representation which The collecting scenes of this dataset include indoor scenes and outdoor scenes (natural scenery, street view, square, etc.). See Fig. Caleb Sangogboye, F., Jia, R., Hong, T., Spanos, C. & Baun Kjrgaard, M. A framework for privacy-preserving data publishing with enhanced utility for cyber-physical systems. Please Are you sure you want to create this branch? (g) H6: Main level of studio apartment with lofted bedroom. Contact us if you have any You signed in with another tab or window. official website and that any information you provide is encrypted This dataset can be used to train and compare different machine learning, deep learning, and physical models for estimating occupancy at enclosed spaces. Saha H, Florita AR, Henze GP, Sarkar S. Occupancy sensing in buildings: A review of data analytics approaches. Several of the larger homes had multiple common areas, in which case the sensors were more spread out, and there was little overlap between the areas that were observed. (b) Average pixel brightness: 43. Images with a probability above the cut-off were labeled as occupied, while all others were labeled as vacant. Currently, rice panicle information is acquired with manual observation, which is inefficient and subjective. In the last two decades, several authors have proposed different methods to render the sensed information into the grids, seeking to obtain computational efficiency or accurate environment modeling. Example of the data records available for one home. The homes tested consisted of stand-alone single family homes and apartments in both large and small complexes. Review of occupancy sensing systems and occupancy modeling methodologies for the application in institutional buildings. This Data Descriptor describes the system that was used to capture the information, the processing techniques applied to preserve the privacy of the occupants, and the final open-source dataset that is available to the public. and transmitted securely. This is most likely due to the relative homogeneity of the test subjects, and the fact that many were graduate students with atypical schedules, at least one of whom worked from home exclusively. From these verified samples, we generated point estimates for: the probability of a truly occupied image being correctly identified (the sensitivity or true positive rate); the probability of a truly vacant image being correctly identified (the specificity or true negative rate); the probability of an image labeled as occupied being actually occupied (the positive predictive value or PPV); and the probability of an image labeled as vacant being actually vacant (the negative predictive value or NPV). Variable combinations have been tried as input features to the model in many different ways. M.J. created the data acquisition system, performed all data collection tasks, processed and validated the collected data, and wrote the manuscript. (b) Waveform after applying a mean shift. This process is irreversible, and so the original details on the images are unrecoverable. and S.S. conceived and oversaw the experiment. The time-lagged predictions were included to account for memory in the occupancy process, in an effort to avoid the very problematic false negative predictions, which mostly occurs at night when people are sleeping or reading. Note that the term server in this context refers to the SBC (sensor hub), and not the the on-site server mentioned above, which runs the VMs. A tag already exists with the provided branch name. The data acquisition system, coined the mobile human presence detection (HPDmobile) system, was deployed in six homes for a minimum duration of one month each, and captured all modalities from at least four different locations concurrently inside each home. Luis M. Candanedo, Vronique Feldheim. For example, images and audio can both provide strong indications of human presence. Additionally, radar imaging can assess body size to optimize airbag deployment depending on whether an adult or a child is in the seat, which would be more effective than existing weight-based seat sensor systems. Performance of a k-nearest neighbors classifier on unprocessed audio (P0), and audio data as publicly available in the database (P1). At the end of the collection period, occupancy logs from the two methods (paper and digital) were reviewed, and any discrepancies or questionable entries were verified or reconciled with the occupants. Room occupancy detection is crucial for energy management systems. Full Paper Link: https://doi.org/10.1109/IC4ME253898.2021.9768582. Figueira, D., Taiana, M., Nambiar, A., Nascimento, J. Computing Occupancy grids with LiDAR data, is a popular strategy for environment representation. Currently, Tier1 suppliers in the market generally add infrared optical components to supplement the shortcomings of cameras. When they entered or exited the perimeter of the home, the IFTTT application triggered and registered the event type (exit or enter), the user, and the timestamp of the occurrence. occupancy was obtained from time stamped pictures that were taken every minute. Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the 2022-12-10 18:11:50.0, Euro NCAP announced that starting in 2022, it will start scoring child presence detection, a feature that detects that a child is left alone in a car and alerts the owner or emergency services to avoid death from heat stroke.. WebExperimental data used for binary classification (room occupancy) from Temperature,Humidity,Light and CO2. The results show that feature selection can have a significant impact on prediction accuracy and other metrics when combined with a suitable classification model architecture. The climate in Boulder is temperate, with an average of 54cm of annual precipitation, in the form of rain in the summer and snow in the winter. 0 datasets 89533 papers with code. See Fig. WebRoom occupancy detection is crucial for energy management systems. TensorFlow, Keras, and Python were used to construct an ANN. At present, from the technical perspective, the current industry mainly uses cameras, millimeter-wave radars, and pressure sensors to monitor passengers. Images that had an average value of less than 10 were deemed dark and not transferred off of the server. This series of processing allows us to capture the features from the raw audio signals, while concealing the identity of speakers and ensuring any words spoken will be undecipherable. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. Cite this APA Author BIBTEX Harvard Standard RIS Vancouver The data includes multiple age groups, multiple time periods and multiple races (Caucasian, Black, Indian). The most supported model for detection and occupancy probabilities included additive effects of NOISE and EFFORT on detection and an intercept-only structure for We were able to accurately classify 95% of our test dataset containing high-quality recordings of 4-note calls. (d) Average pixel brightness: 10. Four different images from the same sensor hub, comparing the relative brightness of the images, as described by the average pixel value. It includes a clear description of the data files. As necessary to preserve the privacy of the residents and remove personally identifiable information (PII), the images were further downsized, from 112112 pixels to 3232 pixels, using a bilinear interpolation process. The site is secure. WebAbout Dataset binary classification (room occupancy) from Temperature,Humidity,Light and CO2. Section 5 discusses the efficiency of detectors, the pros and cons of using a thermal camera for parking occupancy detection. Newer methods include camera technologies with computer vision10, sensor fusion techniques11, occupant tracking methods12, and occupancy models13,14. In total, three datasets were used: one for training and two for testing the models in open and closed-door occupancy scenarios. A tag already exists with the provided branch name. However, formal calibration of the sensors was not performed. Download: Data Folder, Data Set Description. Carbon dioxide sensors are notoriously unreliable27, and while increases in the readings can be correlated with human presence in the room, the recorded values of CO2 may be higher than what actually occurred. To generate the different image sizes, the 112112 images were either downsized using bilinear interpolation, or up-sized by padding with a white border, to generate the desired image size. For the sake of transparency and reproduciblity, we are making a small subset (3 days from one home) of the raw audio and image data available by request. The homes with pets had high occupancy rates, which could be due to pet owners needing to be home more often, but is likely just a coincidence. Waymo is in a unique position to contribute to the research community with some of the largest and most diverse autonomous driving datasets ever released. Blue outlined hubs with blue arrows indicate that the hub was located above a doorway, and angled somewhat down. (d) Waveform after downsampling by integer factor of 100. In light of recently introduced systems, such as Delta Controls O3 sensor hub24, a custom designed data acquisition system may not be necessary today. Howard B, Acha S, Shah N, Polak J. Specifically, we first construct multiple medical insurance heterogeneous graphs based on the medical insurance dataset. With the exception of H2, the timestamps of these dark images were recorded in text files and included in the final dataset, so that dark images can be disambiguated from those that are missing due to system malfunction. Lists of dark images are stored in CSV files, organized by hub and by day. Sun K, Zhao Q, Zou J. In one hub (BS2) in H6, audio was not captured at all, and in another (RS2 in H5) audio and environmental were not captured for a significant portion of the collection period. The exception to this is data collected in H6, which has markedly lower testing accuracy on the P1 data. The authors declare no competing interests. The publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally identifiable information; indoor environmental readings, captured every ten seconds; and ground truth binary occupancy status. Data Set License: CC BY 4.0. Web[4], a dataset for parking lot occupancy detection. Each home was to be tested for a consecutive four-week period. See Table3 for a summary of the collection reliability, as broken down by modality, hub, and home. To solve this problem, we propose an improved Mask R-CNN combined with Otsu preprocessing for rice detection and segmentation. After training highly accurate image classifiers for use in the ARPA-E SENSOR project, these algorithms were applied to the full collected image sets to generate binary decisions on each image, declaring if the frame was occupied or vacant. 9. The framework includes lightweight CNN-based vehicle detector, IoU-like tracker and multi-dimensional congestion detection model. The environmental modalities are available as captured, but to preserve the privacy and identity of the occupants, images were downsized and audio files went through a series of processing steps, as described in this paper. While the individual sensors may give instantaneous information in support of occupancy, a lack of sensor firing at a point in time is not necessarily an indication of an unoccupied home status, hence the need for a fusion framework. WebDatasets, depth data, human detection, occupancy estimation ACM Reference Format: Fabricio Flores, Sirajum Munir, Matias Quintana, Anand Krishnan Prakash, and Mario Bergs. Rice yield is closely related to the number and proportional area of rice panicles. Predictive control of indoor environment using occupant number detected by video data and co2 concentration. sign in The highest likelihood region for a person to be (as predicted by the algorithm) is shown in red for each image, with the probability of that region containing a person given below each image, along with the home and sensor hub. Spatial overlap in coverage (i.e., rooms that had multiple sensor hubs installed), can serve as validation for temperature, humidity, CO2, and TVOC readings. The temperature and humidity sensor had more dropped points than the other environmental modalities, and the capture rate for this sensor was around 90%. All data is collected with proper authorization with the person being collected, and customers can use it with confidence. WebThe OPPORTUNITY Dataset for Human Activity Recognition from Wearable, Object, and Ambient Sensors is a dataset devised to benchmark human activity recog time-series, Wang F, et al. Structure gives the tree structure of sub-directories, with the final entry in each section describing the data record type. Three of the six homes had pets - both indoor and outdoor cats and one dog. Jocher G, 2021. ultralytics/yolov5: v4.0 - nn.SiLU() activations, weights & biases logging, PyTorch hub integration. Despite its better efficiency than voxel representation, it has difficulty describing the fine-grained 3D structure of a scene with a single plane. Test homes were chosen to represent a variety of living arrangements and occupancy styles. Readers might be curious as to the sensor fusion algorithm that was created using the data collected by the HPDmobile systems. The data described in this paper was collected for use in a research project funded by the Advanced Research Projects Agency - Energy (ARPA-E). Some homes had higher instances of false positives involving pets (see Fig. U.S. Energy Information Administration. Hobson BW, Lowcay D, Gunay HB, Ashouri A, Newsham GR. An Artificial Neural Network (ANN) was used in this article to detect room occupancy from sensor data using a simple deep learning model. Use Git or checkout with SVN using the web URL. Finally, the signal was downsampled by a factor of 100 and the resulting audio signal was stored as a CSV file. The median cut-off value was 0.3, though the values ranged from 0.2 to 0.6. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. Surprisingly, the model with temperature and light outperformed all the others, with an accuracy of 98%. sign in The images from these times were flagged and inspected by a researcher. Audio files were captured back to back, resulting in 8,640 audio files per day. WebThis is the dataset Occupancy Detection Data Set, UCI as used in the article how-to-predict-room-occupancy-based-on-environmental-factors Content Luis M. Candanedo, Vronique Feldheim. If not considering the two hubs with missing modalities as described, the collection rates for both of these are above 90%. The final systems, each termed a Mobile Human Presence Detection system, or HPDmobile, are built upon Raspberry Pi single-board computers (referred to as SBCs for the remainder of this paper), which act as sensor hubs, and utilize inexpensive sensors and components marketed for hobby electronics. ), mobility sensors (i.e., passive infrared (PIR) sensors collecting mobility data) smart meters (i.e., energy consumption footprints) or cameras (i.e., visual The two sets of images (those labeled occupied and those labeled vacant by the YOLO algorithm) were each randomly sampled in an attempt to get an equal number of each type. Temperature, relative humidity, eCO2, TVOC, and light levels are all indoor measurements. The driver behaviors includes Dangerous behavior, fatigue behavior and visual movement behavior. National Library of Medicine This is likely because the version of the algorithm used was pre-trained on the Common Objects in Context (or COCO) dataset24, which includes over 10,000 instances each of dogs and cats. The optimal cut-off threshold that was used to classify an image as occupied or vacant was found through cross-validation and was unique for each hub. Newsletter RC2022. All code used to collect, process, and validate the data was written in Python and is available for download29 (https://github.com/mhsjacoby/HPDmobile). Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. Trends in the data, however, are still apparent, and changes in the state of a home can be easily detected by. Audio processing steps performed on two audio files. Energy and Buildings. Dodier RH, Henze GP, Tiller DK, Guo X. Please Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The illuminance sensor uses a broadband photodiode and infrared photodiode, and performs on-board conversion of the analog signal to a digital signal, meant to approximate the human eye response to the light level. The hda+data set for research on fully automated re-identification systems. The .gov means its official. like this: from detection import utils Then you can call collate_fn The YOLOv5 labeling algorithm proved to be very robust towards the rejection of pets. Ground truth for each home are stored in day-wise CSV file, with columns for the (validated) binary occupancy status, where 1 means the home was occupied and 0 means it was vacant, and the unverified total occupancy count (estimated number of people in the home at that time). The sensors used were chosen because of their ease of integration with the Raspberry Pi sensor hub. Despite the relative normalcy of the data collection periods, occupancy in the homes is rather high (ranging from 47% to 82% total time occupied). This is a repository for data for the publication: Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. Using a constructed data set to directly train the model for detection, we can obtain information on the quantity, location and area occupancy of rice panicle, all without concern for false detections. This dataset adds to a very small body of existing data, with applications to energy efficiency and indoor environmental quality. About Dataset Experimental data used for binary classification (room occupancy) from Temperature,Humidity,Light and CO2. Gao, G. & Whitehouse, K. The self-programming thermostat: Optimizing setback schedules based on home occupancy patterns. Leave your e-mail, we will get in touch with you soon. Luis Candanedo, luismiguel.candanedoibarra '@' umons.ac.be, UMONS. R, Rstudio, Caret, ggplot2. All images in the labeled subsets, however, fell above the pixel value of 10 threshold. Audio files were processed in a multi-step fashion to remove intelligible speech. Occupancy detection of an office room from light, temperature, humidity and CO2 measurements. Energy and Buildings. Installed on the roof of the cockpit, it can sense all areas of the entire cockpit, detect targets, and perform high-precision classification and biometric monitoring of them. 10 for 24-hour samples of environmental data, along with occupancy. ARPA-E. SENSOR: Saving energy nationwide in structures with occupancy recognition. S.Y.T. Research output: Contribution to journal Article Additionally, other indoor sensing modalities, which these datasets do not capture, are also desirable. Environmental data are stored in CSV files, with one days readings from a single hub in each CSV. & Hirtz, G. Improved person detection on omnidirectional images with non-maxima suppression. to use Codespaces. Other studies show that by including occupancy information in model predictive control strategies, residential energy use could be reduced by 1339%6,7. Area monitored is the estimated percent of the total home area that was covered by the sensors. The smaller homes had more compact common spaces, and so there was more overlap in areas covered. The publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally The binary status reported has been verified, while the total number has not, and should be used as an estimate only. The driver behaviors includes dangerous behavior, fatigue behavior and visual movement behavior. Ideal hub locations were identified through conversations with the occupants about typical use patterns of the home. FOIA To show the results of resolution on accuracy, we ran the YOLOv5 algorithm on balanced, labeled datasets at a variety of sizes (3232 pixels up-to 128128 pixels), and compared accuracy (defined as the total that were correctly identified divided by the total classified) across homes. We also cannot discount the fact that occupants behavior might have been altered somewhat by the knowledge of monitoring, however, it seems unlikely that this knowledge would have led to increased occupancy rates. The growing penetration of sensors has enabled the devel-opment of data-driven machine learning models for occupancy detection. Python 2.7 is used during development and following libraries are required to run the code provided in the notebook: The Occupancy Detection dataset used, can be downloaded from the following link. 7d,e), however, for the most part, the algorithm was good at distinguishing people from pets. Audio files are named based on the beginning second of the file, and so the file with name 2019-10-18_002910_BS5_H5.csv was captured from 12:29:10 AM to 12:29:19 AM on October 18, 2019 in H6 on hub 5 (BS5). Fundamental to the project was the capture of (1) audio signals with the capacity to recognize human speech (ranging from 100Hz to 4kHz) and (2) monochromatic images of at least 10,000 pixels. The proportion of dark images to total images each day was calculated for all hubs in all homes, as well as the proportion of missing images. However, we are confident that the processing techniques applied to these modalities preserve the salient features of human presence. OMS is to further improve the safety performance of the car from the perspective of monitoring passengers. Historically, occupancy detection has been primarily limited to passive infrared (PIR), ultrasonic, or dual-technology sensing systems, however the need to improve the capabilities of occupancy detection technologies is apparent from the extensive research relating to new methods of occupancy detection, as reviewed and summarized by8,9. How to Build a Occupancy Detection Dataset? Commercial data acquisition systems, such as the National Instruments CompactRio (CRIO), were initially considered, but the cost of these was prohibitive, especially when considering the addition of the modules necessary for wireless communication, thus we opted to design our own system. Points show the mean prediction accuracy of the algorithm on a roughly balanced set of labeled images from each home, while the error bars give the standard deviations of all observations for the home. Hardware used in the data acquisition system. The data includes multiple ages, multiple time periods and multiple races (Caucasian, Black, Indian). Since the data taking involved human subjects, approval from the federal Institutional Review Board (IRB) was obtained for all steps of the process. See Fig. (a) System architecture, hardware components, and network connections of the HPDmobile data acquisition system. More than 100 million people use GitHub to discover, fork, and contribute to over 330 million projects. Data for each home consists of audio, images, environmental modalities, and ground truth occupancy information, as well as lists of the dark images not included in the dataset. (a) Average pixel brightness: 106. Audio and image files are stored in further sub-folders organized by minute, with a maximum of 1,440minute folders in each day directory. See Fig. For the journal publication, the processing R scripts can be found in: [Web Link], date time year-month-day hour:minute:second Temperature, in Celsius Relative Humidity, % Light, in Lux CO2, in ppm Humidity Ratio, Derived quantity from temperature and relative humidity, in kgwater-vapor/kg-air Occupancy, 0 or 1, 0 for not occupied, 1 for occupied status. The dataset has camera-based occupant count measurements as well as proxy virtual sensing from the WiFi-connected device count. Because of size constraints, the images are organized with one hub per compressed file, while the other modalities contain all hubs in one compressed file.
