Abstract

The invention provides a motion capture system and method based on laser large-space positioning and optical inertia complementation. The system comprises a positioning base station, a positioning piece and a processing unit. The method comprises the steps of: constructing a local area network through the Bluetooth, the WiFi and the server; fixing the positioning base stations to the four cornersof the positioning space to scan the positioning space, and matching the positioning piece to collect optical positioning data of a captured object, wherein the positioning piece is arranged on the body of the captured object, collects optical positioning data and inertial motion capture data of the captured object, transmits the optical positioning data of the captured object through Bluetooth, and transmits the inertial motion capture data of the captured object through WiFi; and the processing unit receives the optical positioning data and the inertial motion capture data of the capture object acquired and transmitted by the positioning piece in real time through Bluetooth and WiFi, and fuses and solves the pose information of the capture object. The system realizes large-space multi-person positioning and motion capture based on laser large-space positioning, optical and inertial complementary motion capture, IK whole-body attitude calculation and other technologies.
