A Collision Detection and Motion Image Synthesis Between a Background Image and a Foreground 3-Dimensional Object

Abstract

In Virtual Reality , it is important to merge an image from the real camera and a synthetic object from computer graphics. For examples, a panoramic image enables user to pan inside its imaging world. But the user can't interact the world, only view around. We introduce the background image and a frontal CG object synthesize method considering with their interactions. The method detects a collision between the background image and the frontal CG object pixel by pixel comparing two depth maps. And, we simulate collision between a synthetic spheral object and a captured room image using this method.
