Research on Localization of Vehicle Backwindow for Binocular Distance Measurement
The scene distance information is obtained by disparity based on binocular stereo vision. It is widely used in scientific research and practical engineering. Two cameras which fixed on ahead of the vehicle are used to capture stereo image pairs. Then the backwindows of the two images are located using Hough transform. The top left corner of the windows can be treated as a pair of matching points to calculate the distance of the front vehicle according to the principle of binocular stereo vision. The distance measurement scheme is presented. The experimental results demonstrated that the algorithm provides accurate localization and can help driver to deal with traffic problem to some extent.
