  • Patent number: 11804059
    Abstract: The present disclosure provides a pedestrian re-identification method and apparatus. The pedestrian re-identification apparatus detects a pedestrian to be identified in a specified video frame, and within a specified time period before the capture time of the specified video frame, extracts all pedestrians appearing in the captured video frame and taking them to be historical pedestrians; calculating the feature distances between the pedestrian to be identified and the historical pedestrians; in order of feature distance, from small to large, extracting historical pedestrian identifications corresponding to a predetermined number of feature distances, and clustering the extracted historical pedestrian identifications so as to re-identify the pedestrians to be identified. The present disclosure effectively suppresses external noise interference and improves the success rate of pedestrian re-identification.

  • Publication number: 20230206642
    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.

  • Patent number: 11257293
    Abstract: The invention discloses an augmented reality method and device, and relates to the field of computer technology. A specific implementation of the method includes: acquiring video information of a target, and acquiring real image information and real sound information of the target from the same; using the real image information to determine at least one image-based target state data, and using the real sound information to determine at least one sound-based target state data; fusing the image-based and sound-based target state data of the same type to obtain a target portrait data; and acquiring virtual information corresponding to the target portrait data, and superimposing the virtual information on the video information. This implementation can identify the current state of the target based on the image information and sound information of the target, and fuse the two identification results to obtain an accurate target portrait.

  • Publication number: 20210201009
    Abstract: The present disclosure provides a pedestrian re-identification method and apparatus. The pedestrian re-identification apparatus detects a pedestrian to be identified in a preset video frame, extract all pedestrians appearing in video frames shot in a preset time period before a shooting time of the preset video frame as historical pedestrians, calculate a feature distance between the pedestrian to be identified and each historical pedestrian of the historical pedestrians, extract historical pedestrian IDs corresponding to a preset number of the feature distances in ascending order of the feature distances, and cluster the historical pedestrian IDs to re-identify the pedestrian to be identified.
