CNR-EXT captures different situations of light conditions, and it includes partial occlusion patterns due to obstacles (trees, lampposts, other cars) and partial or global shadowed cars. The video shows the visual occupancy detection system based deployed at the CNR Research Area in Pisa, Italy. Despite the relative normalcy of the data collection periods, occupancy in the homes is rather high (ranging from 47% to 82% total time occupied). Audio processing was done with SciPy31 io module, version 1.5.0. Minimal processing on the environmental data was performed only to consolidate the readings, which were initially captured in minute-wise JSON files, and to establish a uniform sampling rate, as occasional errors in the data writing process caused timestamps to not always fall at exact 10-second increments. 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. A tag already exists with the provided branch name. Radar provides depth perception through soft materials such as blankets and other similar coverings that cover children. Hobson BW, Lowcay D, Gunay HB, Ashouri A, Newsham GR. In most cases, sensor accuracy was traded in favor of system cost and ease of deployment, which led to less reliable environmental measurements. The model integrates traffic density, traffic velocity and duration of instantaneous congestion. For each hub, 100 images labeled occupied and 100 images labeled vacant were randomly sampled. Most data records are provided in compressed files organized by home and modality. Fisk, W. J., Faulkner, D. & Sullivan, D. P. Accuracy of CO2 sensors. However, formal calibration of the sensors was not performed. See Fig. Even though there are publicly 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. In order to confirm that markers of human presence were still detectable in the processed audio data, we trained and tested audio classifiers on pre-labeled subsets of the collected audio data, starting with both unprocessed WAV files (referred to as P0 files) and CSV files that had gone through the processing steps described under Data Processing (referred to as P1 files). Raw audio files were manually labeled as noisy if some sounds of human presence were audibly detectable (such as talking, movement, or cooking sounds) or quiet, if no sounds of human activity were heard. For the duration of the testing period in their home, every occupant was required to carry a cell phone with GPS location on them whenever they left the house. The temperature and humidity sensor is a digital sensor that is built on a capacitive humidity sensor and thermistor. Specifically, we first construct multiple medical insurance heterogeneous graphs based on the medical insurance dataset. Data Set License: CC BY 4.0. The age distribution ranges from teenager to senior. Thank you! WebIndoor occupancy detection is extensively used in various applications, such as energy consumption control, surveillance systems, and disaster management. government site. Volume 112, 15 January 2016, Pages 28-39. Additional benefits of occupancy detection in homes include enhanced occupant comfort, home security, and home health applications8. Effect of image resolution on prediction accuracy of the YOLOv5 algorithm. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. HPDmobile: A High-Fidelity Residential Building Occupancy Detection Dataset. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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. Each HPDmobile data acquisition system consists of: The sensor hubs run a Linux based operating system and serve to collect and temporarily store individual sensor readings. "-//W3C//DTD HTML 4.01 Transitional//EN\">, Occupancy Detection Data Set Please Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the Blue outlined hubs with blue arrows indicate that the hub was located above a doorway, and angled somewhat down. R, Rstudio, Caret, ggplot2. Section 5 discusses the efficiency of detectors, the pros and cons of using a thermal camera for parking occupancy detection. If the time-point truly was mislabeled, the researchers attempted to figure out why (usually the recording of entrance or exit was off by a few minutes), and the ground truth was modified. Other studies show that by including occupancy information in model predictive control strategies, residential energy use could be reduced by 1339%6,7. Time series data related to occupancy were captured over the course of one-year from six different residences in Boulder, Colorado. Please read the commented lines in the model development file. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. Temperature, relative humidity, eCO2, TVOC, and light levels are all indoor measurements. Audio and image files are stored in further sub-folders organized by minute, with a maximum of 1,440minute folders in each day directory. Soltanaghaei, E. & Whitehouse, K. Walksense: Classifying home occupancy states using walkway sensing. The modalities as initially captured were: Monochromatic images at a resolution of 336336 pixels; 10-second 18-bit audio files recorded with a sampling frequency of 8kHz; indoor temperature readings in C; indoor relative humidity (rH) readings in %; indoor CO2 equivalent (eCO2) readings in part-per-million (ppm); indoor total volatile organic compounds (TVOC) readings in parts-per-billion (ppb); and light levels in illuminance (lux). (d) Waveform after downsampling by integer factor of 100. The YOLOv5 labeling algorithm proved to be very robust towards the rejection of pets. van Kemenade H, 2021. python-pillow/pillow: (8.3.1). Learn more. Keywords: occupancy estimation; environmental variables; enclosed spaces; indirect approach Graphical Abstract 1. Home layouts and sensor placements. A tag already exists with the provided branch name. 1b,c for images of the full sensor hub and the completed board with sensors. 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. Despite its better efficiency than voxel representation, it has difficulty describing the fine-grained 3D structure of a scene with a single plane. Datatang 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. ARPA-E. SENSOR: Saving energy nationwide in structures with occupancy recognition. Ideal hub locations were identified through conversations with the occupants about typical use patterns of the home. Jocher G, 2021. ultralytics/yolov5: v4.0 - nn.SiLU() activations, weights & biases logging, PyTorch hub integration. (b) H2: Full apartment layout. Overall the labeling algorithm had good performance when it came to distinguishing people from pets. Since the subsets of labeled images were randomly sampled, a variety of lighting scenarios were present. Days refers to the number of days of data that were released from the home, while % Occ refers to the percentage of time the home was occupied by at least one person (for the days released). Jacoby M, Tan SY, Mosiman C. 2021. mhsjacoby/HPDmobile: v1.0.1-alpha. Received 2021 Apr 8; Accepted 2021 Aug 30. The data covers males and females (Chinese). WebThe OPPORTUNITY Dataset for Human Activity Recognition from Wearable, Object, and Ambient Sensors is a dataset devised to benchmark human activity recog time-series, See Fig. Test subjects were recruited from the testing universitys department of architectural engineering graduate students and faculty in the front range of Colorado. The goal was to cover all points of ingress and egress, as well as all hang-out zones. Occupancy Detection Data Set: Experimental data used for binary classification (room occupancy) from Temperature, Humidity, Light and CO2. Predictive control of indoor environment using occupant number detected by video data and co2 concentration. We also quantified detections of barred owls ( Strix varia ), a congeneric competitor and important driver of spotted owl population declines. False positive cases, (i.e., when the classifier thinks someone is in the image but the ground truth says the home is vacant) may represent a mislabeled point. 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. Our team is specifically focused on residential buildings and we are using the captured data to inform the development of machine learning algorithms along with novel RFID-based wireless and battery-free hardware for occupancy detection. Leave your e-mail, we will get in touch with you soon. Created by university of Nottingham See Fig. Due to the increased data available from detection sensors, machine learning models can be created and used In an autonomous vehicle setting, occupancy grid maps are especially useful for their ability to accurately represent the position of surrounding obstacles while being robust to discrepancies Readers might be curious as to the sensor fusion algorithm that was created using the data collected by the HPDmobile systems. Since the hubs were collecting images 24-hours a day, dark images accounted for a significant portion of the total collected, and omitting these significantly reduces the size of the dataset. Data Set: 10.17632/kjgrct2yn3.3. Dataset: Occupancy Detection, Tracking, and Esti-mation Using a Vertically Mounted Depth Sensor. Work fast with our official CLI. Description Three data sets are submitted, for training and testing. (c) and (d) H3: Main and top level (respectively) of three-level home. U.S. Energy Information Administration. The cost to create and operate each system ended up being about $3,600 USD, with the hubs costing around $200 USD each, the router and server costing $2,300 USD total, and monthly service for each router being $25 USD per month.
