Multi-person mixed human body tumble detection system and method based on double cameras

The invention discloses a multi-person mixed human body tumble detection system and method based on double cameras. The system comprises an image acquisition module, a target recognition module, a joint extraction module and an action recognition module. The image acquisition module is used for acquiring a real-time video stream and preprocessing the video stream to obtain an acquired image; the target recognition module is used for performing human body target recognition based on the acquired image to obtain a human body target image; the joint extraction module is used for extracting human skeleton joints based on the human target image to obtain human joint data; and the action recognition module is used for generating a human body action sequence based on the continuously collected human body joint data, and performing human body action recognition based on the human body action sequence to obtain a recognition result. By adding the YOLO model, the accuracy and efficiency of detecting a plurality of huma
