We have developed a new flow-motion generation method that links the scaling and translation parameters of multi-view images with the position of a moving object in those images. Instead of calibrating extrinsic parameters, we used homographies between flat floors in images taken by each cameras, vanishing points in the vertical and horizontal directions, and the size of a reference object which was shot beforehand. We combined our new system with a system that tracks the positions of moving objects from multi-view images and demonstrated the flow-motion of moving objects.
