Virtual reality driving method and virtual reality system based on arm motion capture

Abstract

The present invention discloses a virtual reality driving method and a virtual reality system based on arm motion capture. The method comprises: when a human body wears a motion capturing system, initializing a preset posture to obtain initial posture data; capturing real-time posture data of the human body, and according to the real-time posture data and the initial posture data, determining a first arm posture by using a transformation matrix method between links of the arm; and according to a preset built-in model, converting the first arm posture into a second arm posture of a preset virtual character, and driving a preset virtual character according to the second arm posture. By using the technical scheme of the present application, according to the obtained initial posture data andreal-time posture data, the arm posture data can be determined by using an arm motion link structure in the form of a transformation matrix between the links, and the accuracy of the arm motion recognition can be determined; and based on the built-in model, the arm posture data is converted to drive the motion of a 3D virtual character, so that the arm spatial position of the virtual character isconsistent with the spatial position of the real character.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to a virtual reality driving method and a virtual reality system based on arm motion capture. Background technique [0002] Virtual reality (VR) is a new technology that "seamlessly" integrates real world information and virtual world information. Through cutting-edge technologies such as computers, it combines reality and illusion that could not be experienced in the real world. After the simulation is superimposed, the imaginary characters or objects are superimposed on the real world, which is perceived by human visual senses, so as to achieve an experience beyond reality. In this way, the real environment and illusory objects can be superimposed into the same space in real time. Existing virtual reality is generally based on the motion capture system to recognize human body movements, and control virtual reality characters according to human body movements, especi...

AI Technical Summary

Problems solved by technology

However, the effect of capturing arm movements in the above-mentioned way is not good. For example, the method based on computer vision is easily disturbed by the external environment, such as lighting conditions, backgrounds, and occluders; the method based on inertial sensors is affected by measurement noise and wandering. Influenced by factors such as errors, it is impossible to track accurately for a long time
