Abstract

The invention relates to the technical field of artificial intelligence, and provides a video-based motion evaluation method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a first motion video of a user and a second motion video of a coach; identifying the motion type of the user according to the first motion video; extracting a first key frame image in the first motion video and a second key frame image in the second motion video according to the motion type; detecting a first human body key point in the first key frame image and detecting a second human body key point in the second key frame image; calculating the difference degree between the first human body key point and the second human body key point; and evaluating the exercise score of the user according to the difference degree and the exercise type. According to the method, the key frame image can be adaptively extracted according to the motion type, the difference degree iscalculated, the motion of the user is evaluated in combination with the motion type and the difference degree, and the accuracy is higher. In addition, the invention also relates to a blockchain technology, and the motion score can be stored in a blockchain node.

Description

technical field [0001] The invention relates to the technical field of video processing in artificial intelligence, in particular to a video-based motion evaluation method, device, computer equipment and storage medium. Background technique [0002] With the progress of society, people's awareness of fitness is gradually increasing, but due to the limitation of fitness venues and time, the demand for taking fragmented time to do fitness exercises at home is gradually increasing, and the teaching videos of body movements launched by various sharing platforms are also increasing. more and more. [0003] In order to evaluate the body movements of home users and allow home users to know their own sports effects objectively, in the prior art, the key frames in the user's sports video and the standard sports video are usually extracted, and then the key frames are compared by a body recognition model. Computes the user's athletic score. [0004] However, regardless of the type o...
