APPLICATION OF 3D ANALYSIS TECHNOLOGY OF VISION SYSTEM IMAGE IN SPORTS MEDICINE

ABSTRACT Background: Objective: The study of sports biomechanics in medicine usually requires a special image analysis system (software) to obtain 3D kinematics data. Taking the swimming project as an example, water images have always been relatively complicated and difficult. As light travels different media, it will refract reflect. When testing underwater movements, if only land camera or is used for testing, error caused by refraction be larger, which affect accuracy test data even more. Methods: breaststroke movement three-dimensional measurement method based on Kwon3D introduced. This from simple test. It combining camera. Two cameras two were simultaneously calibrate space with same calibration frame experiment after analyzing verifying reconstruction. Results: comprehensive reconstruction small, average relative less than 1%. Conclusions: application technology vision systems reasonable worth promoting. Level evidence II; Therapeutic studies - investigation treatment results.
