Vehicle speed sensor for real-time video stream matching method based

The present invention discloses a method based on real-time vehicle speed sensor matches the video stream, the number of two-vehicle camera to take an image of the target object in the same corner of the pixel movement in the reverse thrust of the vehicle travel time interval the two images displaced to obtaining the vehicle speed, thereby providing real-time speed information for the driver, using this method only need to install an on-board camera monitoring vehicle speed can be achieved, the impact of the vehicle manufacturing and assembly errors and the tire wear problems of the measured vehicle speed does not exist, convenient and feasible.
