LINE POSITION ESTIMATION DEVICE, METHOD, AND PROGRAM

The area recognition image generation means 81 generates an area recognition image including a road area from an area recognition image which is a captured image of the front of a vehicle. The overhead view image generation means 82 generates a first overhead view image obtained by converting the generated area recognition image into an overhead view image. The line position estimation means 83 estimates a position of line marked on a road surface from the road area identified by the generated first overhead view image, based on a principle of lane boundaries.
