A Method of Position Sense for Encoding of Virtual Space Information

Abstract

Recently, establishment of real time encoding and transmission techniques of real space 3D information is required in MPEG-4 and so on. In this report, we report a sense method of moving object position as its basic technique. We developed a method of position sense based on four directions video focused on a moving object using the multiple cameras system. By using image processing PCI board, the video images of the moving object are separated to background and foreground, and rectangle coordinates of foreground are calculated rapidly. High accuracy position sense of the moving object is calculated by camera calibration using 3D position sensor and rectangle coordinates of foreground. Besides we report "IPT" virtual reality system using these position data and video images.
