[0051] Example
[0052] Such as Figure 1 to Figure 3 As shown, the sit-up detection system based on the identification of key points of the human body and bones of the present invention includes:
[0053] The image acquisition module uses a high-definition camera to acquire the video image of the subject during the test period frame by frame;
[0054] The image recognition module extracts and recognizes the subject's human body frame and key points of human bones in consecutive frames. The line formed by the waist key points and the shoulder key points is used as the relative horizontal line during initialization; the specific initialization process is: one person goes up Lie flat on the back, the detected line connecting the key points of the waist and shoulders is used as the relative horizontal line of the test. Later, the line of other people during the test is compared with this relative horizontal line to calculate the angle;
[0055] The motion detection module detects the ch...
