Abstract

The embodiment of the invention provides a human body action data acquisition method and device. The method comprises the following steps: collecting optical motion capture data, collecting inertial motion capture data, and calculating to obtain human body motion data by adopting the optical motion capture data and the inertial motion capture data, so that the finally obtained human body motion data is more stable, data errors caused by a single motion capture system is eliminated to a certain extent, and advantage complementation is formed at the same time; and obtaining more accurate human body motion data by combining the accuracy of the spatial position in visual information and the characteristics of high sensitivity and good dynamic performance of the inertial sensor.

Description

technical field [0001] The present invention relates to the technical field, in particular to a method and device for acquiring human motion data. Background technique [0002] In recent years, with the rapid advancement of the commercialization and popularization of VR (Virtual Reality) around the world, the VR interaction method has also developed from a flat interface to a virtual space tracking interaction, which places great emphasis on immersion. "In the virtual world, a motion capture system is essential. [0003] VR motion capture technology is the process of accurately measuring and recording the trajectory and posture of real people in real-time three-dimensional space, and restoring the motion state at each moment to the virtual three-dimensional space, so that the movements and expressions of virtual characters can Natural and realistic like a real person. The motion capture system used in VR is divided into two categories: inertial motion capture and optical m...
