The invention provides a lane deviation detection method and device. The method comprises the following steps: obtaining a video image of the condition of a road ahead of a running vehicle; obtaining an edge mapping image of the video image; obtaining multiple peak points in the edge mapping image; obtaining lane lines according to the multiple peak points; and detecting the lane deviation according to the lane lines. According to the method provided by the embodiment of the invention, the video image of the condition of the road ahead of the running vehicle is obtained in real time, the lane lines are obtained through computing processing, the lane deviation is detected and early warning is carried out according to the lane lines, the method can adapt to days and nights and various complex road conditions, is low in computation complexity, and good in timeliness, and driving safety is improved.
