OVERTAKING VEHICLE DETECTION USING IMPLICIT OPTICAL FLOW

In this paper, the authors present an optical flow-based detection system which can be used for detecting vehicles approaching the blind spot of a vehicle. A predicted image, given camera parameters and vehicle velocity, is first computed. The image is the compared against an actual image, with non-matching areas presumed to be caused by an obstacle. This technique is advantageous in that an optical flow field does not need to be explicitly calculated. Additionally the techniques is sensitive to vertical obstacles but is able to ignore lane markers and shadows cast by stationary objects.
