PROBLEM TO BE SOLVED: To solve the problems of a conventional road marking recognition device that divides the whole image captured by a camera into areas and then performs conversion such as projection to a two-dimensional plane, thereby increasing CPU load, and the problem of a calculation complexity reducing method for recognizing a road marking based on a brightness change position on a detection line, which cannot correctly recognize the road marking if the other vehicle in front of a vehicle hides a part of the road marking. SOLUTION: A monitoring area setting means sets a partial area in an image obtained by capturing a predetermined area including a traveling lane of a vehicle, which is obtained by an image input means, as a monitoring area. An image feature extraction means extracts an image feature from the monitoring area. An HMM identification means compares and evaluates the feature obtained by the feature extraction means and a road marking model stored in advance in a road marking model storage means by using HMM to recognize the road marking.
