  • Method and device for acquiring information, and system for detecting attention degree
    Patent number: 12469295
    Abstract: The present disclosure provides an information acquiring method and apparatus, and an attention degree detecting system. The information acquiring method includes: acquiring a video frame captured by a video capturing equipment detecting whether a pedestrian exists in the video frame by using a first deep-learning model; processing the video frame by using a second deep-learning model to generate a pedestrian bounding box of the pedestrian under a condition that the pedestrian exists in the video frame, and assigning a corresponding pedestrian identifier to the pedestrian bounding box; identifying an image in the pedestrian bounding box by using a third deep-learning model to identify feature information of the pedestrian; and writing a pedestrian historical data into a database, wherein the pedestrian historical data comprises a timestamp and an identifier of the video frame, coordinate information of the pedestrian bounding box, the pedestrian identifier and the feature information of the pedestrian.
