To solve the problem of contour reconstruction of moving vehicle on monocular vision, the authors propose a new algorism based on video sequence. In this paper, we obtain the motion parameters of unconstrained moving vehicle by solving the characteristic equations, and convert the contour reconstruction problem of unconstrained moving vehicle into the problem of constrained moving vehicle. Experiments show that the new algorism can reconstruct contour of different vehicle, and the error of vehicle height estimation is less than 4%.
