Beschreibung
Zusammenfassung:	A road surface area detection device, which is capable of accurately determining a road surface shape, includes: a data accumulator accumulating a ranging point sequence measured in a circumferential direction for each depression angle by a sensor; an adjacent point specifying processing circuitry extracting an attention point in one of the ranging point sequences, and adjacent points located on a large depression angle side and a small depression angle side with respect to the depression angle for the one ranging point sequence; an angle calculator calculating an angle formed by the adjacent points with respect to the attention point, as a difference angle; and a shape calculator classifying the attention point based on a shape determination result using the attention point and the adjacent points, and calculates a road surface shape based on the classification.
