Human motion capture system and capture method based on dual somatosensory tracking system

Abstract

The invention discloses a human body motion capture system and a capturing method based on a dual somatosensory tracking system. The human body motion capture system based on a dual somatosensory tracking system includes two somatosensory tracking systems, a checkerboard, a data acquisition module, and a motion analysis module. . The human motion capture method includes the following steps: equipment placement, calibration image collection, human posture collection, somatosensory tracking system calibration, somatosensory tracking system synchronization, fusion filtering, and joint angle output. The invention has strong practicability, avoids the complicated operation of marking and sticking points on the subject, and can directly capture the three-dimensional coordinate position of the athlete's joint point; it is simple to set up, and only requires simple calibration picture collection to complete the setting; low cost Low, the cost is greatly reduced compared to traditional human motion capture equipment; the body posture capture of the somatosensory tracking sensor has been specifically improved to improve the accuracy and robustness of its human motion capture.

Description

technical field [0001] The invention relates to the field of motion image analysis, in particular to the field of human movement capture, in particular to a human body motion capture system and capture method based on a dual somatosensory tracking system. Background technique [0002] Human motion capture is one of the core issues in the study of sports biomechanics. Accurate and robust joint point positions and joint angle changes are reasonable prerequisites for subsequent kinematic analysis. The current mainstream human motion capture method has a series of defects such as high cost, complicated setting and unfavorable promotion and use. Further technical research is needed to solve and improve these problems. [0003] At present, human motion capture systems and methods commonly used in laboratory environments are human motion capture systems and methods with markers based on infrared light, and the typical representatives are Vicon system and Quallysis system. The coll...

Problems solved by technology

When Kinect is directly used for human motion capture, its accuracy is generally difficult to meet the requirements, especially when the human body does not face Kinect or there are many self-occlusion actions, it is difficult for Kinect to judge the specific position of some coordinate points, which in turn affects the entire human body posture identification
