Moving posture capture system

Abstract

The invention relates to a moving posture capture system, which comprises a plurality of sensors used for measuring moving posture and a host computer used for processing posture data, wherein, an inertia posture measure sensor module enables bidirectional connection with a master control module through a USART communication cable, the master control module and the host computer enable bidirectional connection in a wireless mode, and the power supply management module is respectively connected to the inertia posture measure sensor module and the master control module. The system integrates a triaxial magnetic field sensor and a six spindle acceleration and angular velocity sensor, the inertia strapdown posture is used for resolving, Kalman digital filtering and data fusion algorithm are combined to accurately measure three-dimensional stereo, the collected data can be automatically corrected without the influence of environmental factors, the moving postures of human, animal and objects can be captured, the data output by the system can be directly used by the users, and high quality animation with vivid effect can be produced. The moving posture capture system can be used for dynamic simulation of role models of cartoon, movie and television and game, as well as scientific research of motion state of human, animal and objects.

Description

technical field [0001] The invention relates to data collection of motion postures, in particular to a motion posture capture system. Background technique [0002] 3D dynamic / static simulation is becoming more and more important in today's digital age. If the dynamic simulation of animation, film and game role models is made by using physical modeling or manual drawing, it is obviously not suitable for the trend, low efficiency, heavy workload and high cost. . As people's requirements for motion simulation of character models are getting higher and higher, the requirements for the efficiency, convenience of use, precision and cost of motion capture systems are also getting higher and higher, which requires the system to be low-cost, simple and Ease of use, high precision and high efficiency are developed. Motion capture systems are increasingly used in the production of 3D dynamic simulation of animation, film and television and games, and 3D dynamic simulation has become ...
