Abstract
The apparatus includes: a frontward imaging unit configured to capture an image ahead of the moving body; a frontward division line detection unit configured to detect a shape of a division line of a road surface, from the captured image, and calculate reliability of a frontward division line shape; a periphery imaging unit configured to capture an image of a periphery of the moving body; a periphery division line detection unit configured to detect a shape of the division line on the road surface, from the captured image, and calculate reliability of a periphery division line shape; and a division line shape determination unit configured to determine the shape of the division line on the road surface where the moving body moves, by selecting one from or combining the frontward division line shape and the periphery division line shape, based on first reliability and second reliability.
