Embodiment 1

[0042]An inertial motion capture system capable of simultaneously collecting and capturing facial expressions of an object, comprising at least one depth camera, several inertial motion acquisition nodes, a transmitting node, a converging node and a terminal, the depth camera is connected to the transmitting node, the The transmitting node is connected to several inertial action collection nodes, the transmitting node is connected to the sink node, and the sink node is connected to the terminal;

[0043] The depth camera is used to collect information on the facial area of ​​the captured object, and establish a three-dimensional model for the facial area of ​​the captured object;

[0044] The inertial action collection node is used to collect the local position acceleration, angular velocity and magnetic strength of the capture object itself;

[0045] The transmitting node is used to collect the information collected by the depth camera and the information collected by the ine...

Embodiment 2

[0052] According to the inertial motion capture system described in Embodiment 1, the difference is that the depth camera is connected to the transmitting node in a wired manner.

[0053] The advantage of the design here is that the depth camera is connected to the transmitting node in a wired manner, which provides a higher data transmission rate than the wireless solution, and due to the reduction of wireless transmitting nodes, the collision of data in the wireless channel is reduced, improving The overall data transmission rate is improved, so that the sink node can obtain higher frequency human body posture data updates.

Embodiment 3

[0055] According to the inertial motion capture system described in Embodiment 1 or 2, the difference is that the transmitting node is connected to several inertial motion acquisition nodes via USB.

Abstract

An inertial motion capture system capable of simultaneously collecting and capturing facial expressions of an object, comprising at least one depth camera, several inertial motion acquisition nodes, a transmitting node, a converging node and a terminal, the depth camera is connected to the transmitting node, the The transmitting node is connected to several inertial motion collection nodes, the transmitting node is connected to the converging node, and the converging node is connected to the terminal; compared with the existing technology, the present invention can effectively simultaneously capture the body movements and facial expression. At the same time, because the single-person inertial motion capture device only needs a set of wireless transceiver modules, compared with the traditional scheme of using 15 to 17 wireless transceiver modules, it reduces system complexity, reduces data delay, and increases data transmission rate.

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...
