Swing attitude correction method, device, equipment and medium based on inertial motion capture

Abstract

Embodiments of the present disclosure relate to a swing posture correction method, device, equipment and medium based on inertial motion capture. Among them, the swing posture correction method based on inertial motion capture includes: in the process of the golfer swinging the baseball bat, using the inertial sensor installed on the baseball bat to collect the club movement data; based on the club movement data to determine Real-time attitude data of key points; wherein, the key points include at least one of the starting point, the highest point of the swing, the hitting point and the end point of the swing; based on the real-time attitude data, the golfer's swing attitude is corrected . Adopt the above-mentioned technical scheme, capture the motion data of the baseball bat through inertial motion capture technology, determine the posture data of the baseball bat at key points, and determine whether the swing posture of the golfer is correct by analyzing the posture data of the key points, thereby improving Accuracy of judging swing posture.

Description

technical field [0001] The present disclosure relates to the technical field of inertial motion capture, and in particular to a swing posture correction method, device, equipment and medium based on inertial motion capture. Background technique [0002] Baseball swing has strict requirements on the repeatability of movements. To achieve a perfect swing, players not only need to refine their swing movements, but also need to compete with masters under the guidance of coaches, so as to discover their own strengths. insufficient. Usually, coaches guide golfers based on experience and the swing posture seen by the naked eye. It is difficult to accurately quantify the data, and it is not easy to find small irregular swing postures. [0003] At present, optical motion capture technology, such as an optical motion capture system based on mark points, is used to capture the golfer's swing posture. Specifically, mark points are pasted on the golfers’ joints, multiple motion capture...

AI Technical Summary

Problems solved by technology

However, the amount of signals collected by the optical motion capture system based on mark points is large, and the space calculation algorithm is complex, and its real-time performance is related to the calculation speed of the data processing unit and the complexity of the calculation algorithm.

And when the system captures the movement of the object, the limbs will block the marker points, which will affect the accuracy of the capture system and even lose the capture target.
