1. A lane recognition apparatus for a vehicle, comprising: an image picking-up section picking up a road image ahead of the vehicle; a lane-marker detecting section detecting a plurality of lane-marker candidate points on the road image; a road model parameter calculating section calculating a road model parameter representative of a road shape ahead of the vehicle on the basis of the lane-marker candidate points; a deviation calculating section calculating a deviation between the lane marker candidate point and an estimated candidate point estimated from the road model parameter; and a lane marker detection feasibility determining section determining whether the road image is employed for detecting the lane marker, on the basis of the deviation.
