The invention discloses a sport data analysis comparison method and device, and the method comprises the steps: obtaining the sport data of a target sporter in a specific time range; extracting the sport data of a target motion segment from the sport data of the target sporter; analyzing the sport data of the target motion segment, and obtaining the posture frame data of key parts of different parts of a human body in the target motion segment; converting the posture frame data of key parts of different parts in the target motion segment into the spatial motion parameters in a human body coordinate system; enabling the set of the posture frame data of key parts of different parts in the target motion segment to serve as the feature vector of the target motion segment, and obtaining a matched corresponding standard motion segment from a preset motion template library; comparing the posture frame data of key parts of different parts in the target motion segment with the posture frame data of key parts of different parts in the standard motion segment, and outputting a comparison result. Therefore, the method enables the key motion data in the sport data to be converted into spatial motion parameters which is small in calculation burden and is visual in expression for motion matching, and effectively improves the data matching efficiency.
Description
technical field [0001] The invention relates to the field of data analysis, in particular to a method and device for analyzing and comparing motion data. Background technique [0002] With the continuous development and improvement of digital technology, the digital rational analysis of sports data has become an important standard to measure the state of sports. By comparing the motion data in the user's motion with the standard motion data, the user can clearly understand the deficiencies of motion gestures in motion. The comparative analysis of action data is widely used in sports posture correction, personal sports exercise analysis, athlete training data analysis, sports competition data analysis and other fields. [0003] The comparison and analysis of sports data generally starts with modeling and identifying the type of action, and then compares the information between the standard action and the target action. In the traditional sports data analysis and comparison ...
