DETECTION OF ADJACENT VEHICLES' MOTION USING OPTICAL FLOW

This paper describes a new approach to detect adjacent vehicles' motion using optical flow and implementation on an on-board vision system that monitors the motions of adjacent vehicles to help fully-automated vehicles take safer and smoother maneuvers. CCD cameras are placed under both side rear-view mirrors for getting rear-view images. The 3-D translational motion parameters are effectively estimated using optical flow vectors generated by vehicles approaching from behind. In general, optical flow calculation imposes heavy computational loads on an image processor, while precise estimation of motion parameters requires usually many exactly-calculated flow vectors over a whole image.
