Live-action navigation system based on automobile data recorder

The invention discloses a live-action navigation system based on an automobile data recorder, the automobile data recorder is provided with a camera module for acquiring video information in front ofa vehicle, the camera module transmits acquired signals to an image processing module, and the image processing module transmits processed data to a video compression module and a display processing module respectively. The video compression module transmits a compressed video stream to the operation control module, the display processing module transmits a video signal to the LVDS decoding moduleof the IHU host through the LVDS encoding module, the LVDS encoding module transmits a decoded video signal to the operation processing module, and the operation processing module acquires a navigation signal of the BD/GPS positioning module. And the operation processing module integrates the navigation signal and the video signal and then transmits the integrated signals to the display screen for displaying and realizing
