Intelligent training system for snowboard big air

In this study, an intelligent training analysis system for snowboard big air was established. Based on the non-contact measurement method of vision, the system used high-speed cameras to build a multi-camera array, combined with 3D space camera calibration technology, human body projection matching, and tracking algorithm to track athletes' movements, capture, identify, and analyze athletes' gestures. In addition, based on the technology of kinematic calculation of external force, this study calculates the kinetics parameters of athletes in the process of take-off through the kinematic parameters of the human body, such as the moment of inertia, rotational kinetic energy, ground reaction force and so on. Finally, it establishes the calculation and analysis system of the kinetics parameters of the snowboard big air at the take-off stage. The system is of great significance to monitoring snowboard big air training.
