Design of action correction assistant system in physical education teaching and training based on .NET platform

In order to improve the training accuracy of sports teaching and training, and promote the scientific and standardized sports teaching and training, a correcting assistant system based on. NET platform is designed. Based on the Microsoft. NET platform, a three-tier architecture is constructed. Among them, the data access layer uses the functions of ADO. NET and. NET XML to realize the exchange of database information, provides services for the business logic layer, designs the motion correction module of the business logic layer, uses Kinect to extract the skeleton angle data characteristics of the trainer's training actions in the motion collection module, adopts the dynamic time planning algorithm to match the corresponding frames, calculates the training scores, realizes the reappearance of motion correction through the 3D reconstruction module, and finally displays the motion correction through the user interface layer. Experimental results show that the system can collect training action and mark the key points, the average score is 8 points, the corresponding frame is matched accurately, and the training action with very satisfactory (A) level reaches more than 90%.
