In this paper, a novel corner matching algorithm is presented. Gradient operator in Harris corner detector is directly used to compute the similarity between corners. Then initial matches are obtained. The algorithm is contrasted with normalized cross-correlation. Its computational complexity is reduced and matching speed is improved effectively because this method only adopts the addition and subtraction...
In this paper, an application of stereo vision on traffic accident investigation is presented. Self-calibration of the stereo rig is utilized to get affine reconstruction. The external parameters between the two cameras are pre-calibrated which help us upgrade the affine structure to Euclidean. So the system not only can measure the real distance in Euclidean space, but also can be a varying focus...
