Abstract: A Kinect-based auxiliary training system for basic badminton movements, includes a data collection module, a movement feature extraction and recognition module, and a movement standard degree analysis and guidance module. The data collection module is provided with a Kinect v2 somatosensory device for monitoring athletes in real time, and collecting 3D coordinate data of 25 joint points of athletes' whole body. The movement feature extraction and recognition module is provided for establishing a standard template, and obtaining a similarity between the movement data and the standard template. The movement standard degree analysis and guidance module is provided for determining a category of the current movement of the user to be tested according to the similarity, and further analyzing whether the current movement of the user to be tested meets a standard according to a threshold range of the bone included angle set by a technology evaluation rule.
