Embodiment

[0053] Such as figure 1 and figure 2 As shown, the mobile phone is placed on the front to shoot the video, and the distance between the key points of the human wrist bones and the crossbar in the continuous frames is detected to determine whether it is in the process of pulling up. By extracting the key points of the face and the key points of the chin The change of the position of the rod, and the change of the included angle between the upper arm (the connection line "shoulder bone key point - elbow bone key point") and the forearm (the connection line "elbow bone key point - wrist bone key point") To judge its effectiveness in the process of ascent, descent and completion of the action.

[0054] The invention provides a pull-up detection system based on key points of bones and faces, including:

[0055] An image acquisition module that processes images collected by the camera to obtain image recognition information;

[0056] An image recognition module that extracts the...

Abstract

The invention discloses a pull-up detection system and method based on bone and face key points. The pull-up detection system comprises an image acquisition module for processing an image acquired bya camera to acquire image recognition information; an image recognition module which is used for extracting face key points, human skeleton key points and cross rod positions; an action detection module which is used for judging whether the pull-up behavior starts and ends or not according to the relative positions of the wrist skeleton key points and the cross rod, judging whether the human bodyascends or descends according to the included angle between the big arm and the forearm, calculating the relative position of the cross rod and the jaw, judging whether one pull-up action is completedor not according to the ascending and descending states and judging the action completion effective degree;; an action counting module which is used for recording the pull-up action completion times;and a data display module is used for displaying the pull-up action completion times.

Description

technical field [0001] The invention relates to a pull-up detection system and method, in particular to a pull-up detection system and method based on bone and human face key points. Background technique [0002] Pull-ups, sometimes referred to as pull-ups, refer to hanging exercises that rely on one's own strength to overcome one's own body weight and do work upwards. It mainly tests the development level of upper limb muscle strength, as well as arm strength and waist and abdomen strength. It is a multi-joint compound movement exercise and a better way to exercise upper limbs. It is one of the test selection items for the high school entrance examination and high school physical education examination. One of the important reference standards and items of physical fitness. [0003] The existing continuous pull-up performance test method is to specify the initial position and the end position of each pull-up. The initial position is when the body is straight, the bar is he...
