3D Motion Capture using Rigid Body Models
In this study, we developed a 3D measurement system for capturing the movement of an object with numerous markers by mounting a space conversion optical system on a high-speed vision platform, H3 Vision system. This system measures the 3D translation and rotation of an object with hundreds of markers in real time. Here we introduced several rigid body models for stable 3D motion trackingeven when several markers are occluded. Actually we conducted real-time 3D motion measurement experiments at 1000fps for several quickly moving and rotating objects. and showed the validity of our system. It proves the effectiveness of the high-speed vision for multipoint 3D motion capturing at high speed in real time.
