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.
