A power chain quantitative evaluation index acquisition method, system, terminal and medium

Abstract

This invention discloses a method, system, terminal, and medium for obtaining kinetic chain quantitative evaluation indicators. The method includes: synchronously acquiring inertial data of the limb holding the device and the device; detecting whether a video frame sequence synchronized with the inertial data is acquired; if the video frame sequence is acquired, performing multi-source fusion calculation based on the inertial data and the video frame sequence to obtain the kinetic chain quantitative evaluation indicator; if the video frame sequence is not acquired, performing inertial calculation based on the inertial data to obtain the kinetic chain quantitative evaluation indicator. This invention effectively overcomes the shortcomings of insufficient accuracy of a single vision solution under high-speed motion and the lack of global reference in a single inertial solution by adaptively switching between multi-source fusion and pure inertial dual-modal calculation strategies. It achieves accurate, robust, and convenient quantitative evaluation of kinetic chain transmission efficiency under different equipment configurations and environmental conditions.
