Realization of a hybrid human motion capture system

In this paper, we propose a hybrid human motion capture method that combines the advantages of optical motion capture device and sensor type motion capture device. First, calibration of multiple cameras is performed to obtain position and attitude information of a rigid body composed of markers. Then, 15 AHRS sensor modules were attached to individual segments of the human body, arms, legs, and body to reproduce human skeletal movements by analyzing the kinematic relationship of joint rotation information. By overcoming the disadvantages of motion capture method of optical and sensor type, many people can simultaneously capture motion. From our experiments, an actor was asked to hold different poses with this system and then the motion capture was conducted. It resulted in a 3D character can reproduce the motions of the actor.
