Abstract

The invention discloses a rigid body recognition method, device and system, terminal equipment and computer readable storage medium, and the method comprises the steps: obtaining the coding information of a corresponding rigid body according to the image data, transmitted by a camera, in one recognition period; and identifying the rigid body according to the encoding information and preset rigid body encoding information. According to the technical scheme provided by the invention, the production efficiency of the rigid body and the recognition capability of the active optical motion capture system for the rigid body can be improved.

Description

technical field [0001] The present application belongs to the technical field of motion capture, and specifically relates to a rigid body recognition method, device, terminal equipment, system, and computer-readable storage medium. Background technique [0002] Motion capture is a high-tech technology that measures and records the trajectory or posture of an object in a real three-dimensional space, and reconstructs the state of a moving object in a virtual three-dimensional space. [0003] Existing optical motion capture systems can be divided into active and passive. Passive rigid body optical markers are easy to wear out, and due to problems such as heat dissipation, power supply, and reflective optical path, the brightness of the light source received by the camera is not high, which reduces the ability of the camera to filter external redundant information, and also reduces the camera. working distance. In addition, passive rigid bodies need to be set in different thr...
