Research on the Method of Underwater Swimming Motion Capture

With the development of virtual reality (VR) technology, immersive video content has gradually become a support for the improvement of traditional business processes in various industries. For swimming training, the integration of virtual reality technology to generate high-quality immersive content is useful for athletes to improve their personal sports level. Considering the influence of light refraction, this study proposes a calibration method of underwater 3D measurement system based on refraction compensation, which further improves the calibration accuracy of underwater motion capture and provides a new idea and method for the development of virtual reality technology in underwater.
