A lane recognizing device comprises: an image processing means which performs a process of estimating a lane of a road by processing an image of the road and outputs a result of the process as first lane information; a lane estimating means which performs a process of estimating the lane using a map data of the road and the current position information of a vehicle and outputs a result of the process as second lane information; and an actual lane recognizing means which recognizes an actual lane of the road on the basis of the first lane information and the second lane information. Thereby, even if there is an unpredictable skid mark or road repaired part, it is possible to detect the lane accurately while increasing the opportunities for detecting the lane as much as possible by processing the road image and obtaining the road information and the map data.
