Embodiment

[0074] (1) Badminton recognition and trajectory tracking algorithm

[0075] For the case where there are background people moving in the image, we first obtain a set of frame-based badminton detection candidate regions DJ, where DJ={dmj}, Nj is the number of candidate regions of the detected ball j, and dmj∈R2 is the spatial position information of the mth candidate region of the detected ball j. For a specific individual A, these detected candidate regions need to be connected with A to form a complete badminton trajectory map. We define variables by to measure the distance between two detected candidates and Whether there is a connection, and for all possible connections Find the optimal connection scheme.

[0076] If considering the badminton pair j1 and j2 detected in the image, combining the affinity vector field to filter out the impossible connections in the object heat map points will turn the NP-hard graph matching problem into a maximum full bipartite graph...

Abstract

The invention discloses a badminton motion track monitoring and analyzing system and method. By using of an image detection technology, an image recognition technology, a wireless transmission technology and a data analysis technology, the badminton motion track monitoring and analyzing system and method can achieve real-time monitoring for information such as badminton motion tracks and motion speed, rotation and changing tracks in the process of ball games and continuous movement postures of athletes in the movement process in badminton competitions or in training process. The badminton motion track monitoring and analyzing system can carry out real-time video monitoring and recognition on the motion tracks of balls in the ball games and the movement postures of the athletes so as to facilitate scientific analysis on the ball games by coaches, develop targeted training plans and improve the effect of exercise training.

Description

technical field [0001] The invention relates to a badminton movement trajectory monitoring and analysis system, in particular to a badminton movement trajectory monitoring and analysis system and method. The invention belongs to the technical field of sports identification and analysis application. Background technique [0002] Among sports events, ball games have always been loved and widely participated by the public. As a sport that can show the unity, hard work and progress of a collective team, it has received more and more attention in recent years. Among many competitive sports, collective ball sports have significant characteristics such as high intensity, high skill, fierce confrontation, and teamwork. How to discover the laws of movement of different athletes through scientific testing techniques during competition or training, and then use targeted scientific Training to improve the team's technical and tactical ability is one of the key technologies to improve ...
