Title:
THERMAL INFRARED VISION-BASED PARKING APRON HUMAN BODY ACTION RECOGNITION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/087420
Kind Code:
A1
Abstract:
Disclosed are a thermal infrared vision-based parking apron human body action recognition method and system. The method comprises: obtaining a plurality of video sequences from an infrared monitoring video; performing target frame labeling on a set target in each image frame in the video sequences; for each image frame in the video sequences, capturing an enlarged region of a target frame according to the labeled target frame; adding position information of labeled images of the target frames to the enlarged regions of the target frames to obtain three-way channel sub-images; the three-way channel sub-images forming a three-way channel sub-image sequence according to a time sequence; training an action recognition model by using the three-way channel sub-image sequence corresponding to the plurality of video sequences as a training set; obtaining from the infrared monitoring video a video sequence to be recognized, and obtaining a three-way channel sub-image sequence corresponding to the video sequence to be recognized; and inputting the three-way channel sub-image sequence corresponding to the video sequence to be recognized into the trained action recognition model to output a target action type. In the present invention, the recognition precision of human body actions in a complex environment is improved.
