Vehicle movement path prediction method of an in-tunnel

The present invention provides a vehicle movement path prediction method of an in-tunnel, which first of all to a period designated by the user from a plurality of cameras are arranged, and take a number of pictures designated by the user every time inside the tunnel, the photo processing result and Photos library matching information of the vehicle is determined sign; then dividing the threshold value of the photo, and a series of median filtering process, in conjunction with the motion vector to update the next target position of the vehicle in the tunnel, complete tracking and dynamic prediction of the vehicle. The present invention can effectively get the information inherent in the photo, and this information timely feedback to the driver, providing a wealth of content basis for analyzing the running condition of the vehicle in the tunnel accurately.
