Physical education teaching auxiliary system and method based on human body posture recognition

Abstract

The invention discloses an interactive physical education teaching auxiliary system and method based on human body posture recognition. The system comprises a depth camera device, which is used for acquiring a user action depth image sequence and a standard action depth image sequence; a conventional camera device for acquiring a standard motion demonstration image sequence; A standard movement training unit for establishing a standard movement model; a standard action storage unit for storing a standard action model and a standard action demonstration image sequence; a display terminal for displaying a standard action demonstration image sequence to a user; An action comparison unit configured to compare a user action depth image sequence at a predetermined time point or time period witha standard action model at a corresponding time point or time period, and obtain a difference between the user action and the standard action model; a presentation means for outputting action evaluation or action correction presentation information to the display means according to the difference. The invention does not require a user to wear a special identification device, and the system manufacturing cost is reduced and the user experience is improved.

Description

technical field [0001] The invention relates to computer vision technology, in particular to a physical education teaching auxiliary system and method based on human body posture recognition. Background technique [0002] Traditional physical education requires venues and coaches, and is limited by trainers' economic conditions, training venues, training time, etc., which is not conducive to most users meeting their learning goals. Learning with the help of teaching videos is not interactive, nor can you evaluate your actions, and you cannot get timely corrections when you make mistakes. Choose to watch games or performance videos to learn by imitation. Although users can complete it at any time and in any environment, there is a lack of guidance, no evaluation system for actions, and the training effect cannot meet the needs of users. [0003] The prior art discloses a device and a corresponding method for obtaining human body motion-assisted physical education teaching by...

Problems solved by technology

[0004] However, this type of teaching assistance system that uses a recognition device that needs to be worn by the human body requires the user to wear a special recognition device. Although it can also realize the learning and competition of sports with simple movements, it cannot be used to learn sports with more movement changes. high system cost
