Inertial motion capture system capable of collecting and capturing face expression of object at the same time and operation method thereof

Abstract

An inertial motion capture system capable of collecting and capturing the face expression of an object at the same time comprises at least one depth camera, multiple inertial motion collection nodes, a transmitting node, an aggregation node and a terminal. The depth cameras are connected with the transmitting node, the transmitting node is connected with the inertial motion collection nodes and the aggregation node, and the aggregation node is connected with the terminal. Compared with the prior art, the inertial motion capture system can effectively capture the limb motion and face expression of the human body at the same time. Meanwhile, because the single-person inertial motion capture equipment only needs one wireless receiving and transmitting module, compared with a traditional scheme needing 15-17 wireless receiving and transmitting modules, system complexity is reduced, data delay is reduced, and the data transmission rate is increased.

Description

technical field [0001] The invention proposes an inertial motion capture system capable of simultaneously collecting and capturing facial expressions of objects and an operating method thereof, belonging to the technical field of motion capture and image processing. Background technique [0002] Inertial Motion Capture System (Inertial Motion Capture System) is also called MEMS Motion Capture System. Since its appearance, the inertial motion capture system has been developing towards miniaturization and integration, and overcomes the problems of expensive equipment, complicated installation, susceptibility to ambient light, and occlusion of the widely used optical motion capture system. An inertial motion capture system is an implementation of a motion capture system. Since the motion capture system took shape in the 1880s, several universities and laboratories in the United States began to conduct theoretical research on the technology involved in it in the 1980s. With the...
