  • SYSTEMS AND METHODS OF TRAFFIC MEASUREMENT USING IMAGE CAPTURE DEVICES VIA COMPUTER VISION
    Publication number: 20250037473
    Abstract: Systems and methods for traffic measurement are disclosed. An image capture device is configured to generate image data including an area of interest within a physical environment containing at least one engagement feature. The image data is received and model input image data including a plurality of cropped images is generated by applying a zoom-in crop process to the image data. An image processing model generates a person count and dwell time. The image processing model receives the model input image data as an input. An engagement metric is generated based on the person count and the dwell time. The engagement metric is representative of engagement with the at least one engagement feature.
