Abstract

In this paper, we describe a high speed optical motion capture method that has a simple mechanism. We use a light shielding filter using a pattern of Single-Track Gray Code (STGC) [1] absolute encoder to take location of IR light marker tags instead of high-speed camera or row of binary coded masks. Therefore, this system can convert the position coordinate of tags into the digital signal directly, and it can track faster than the traditional method, with only the combination of inexpensive optical parts.

Using motion capture for interactive motion editing
VRCAI '14: Proceedings of the 13th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and its Applications in Industry

Motion capture technology has been widely used for creating character motions. Motion editing is usually also required to adjust captured motions. Because character poses which include joint rotations, body positions, and orientations are high-...
Comparing two methods for acquiring 3D data of motion capture system by using PSD camera and CCD camera
ICHIT '09: Proceedings of the 2009 International Conference on Hybrid Information Technology

This paper presents a monocular PSD-based motion capture system and CCD camera based system. The first system includes a PSD (Position Sensitive Detector) and active infrared (IR) LED markers that are placed on the object to be tracked. The PSD sensor ...
Accurate realtime full-body motion capture using a single depth camera

We present a fast, automatic method for accurately capturing full-body motion data using a single depth camera. At the core of our system lies a realtime registration process that accurately reconstructs 3D human poses from single monocular depth images,...
