Problems solved by technology

[0004] In the method of automatic detection of road differences, the following two methods are mostly used to determine the difference area: first, the direct difference method, which needs to pre-set the road width threshold, and then cover the road width of the navigation road network in the trajectory image The part of the area within the threshold range is deleted, and the part of the track image that covers the navigation road network outside the road width threshold range is used as the difference area; because the width of different roads is different, the preset road width threshold is different. It is suitable for all roads, so it is prone to accidental deletion or wrong deletion, and the difference area determined by this method is not accurate enough; second, the method of refining the track image and then making a difference adopts the method of morphology, statistics or image gradient , first refine the trajectory image to a certain number of trajectories; if the refined trajectory is small, the road information display will not be comprehensive; Factors will form strong noise, which will seriously affect the detection effect of the difference area
