RELIABILITY DETERMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reliability determination device capable of determining reliability with respect to the detection result of a compartment line.SOLUTION: A reliability determination device (1) includes: light emission parts (3, 5) disposed in a vehicle (201) for irradiating a road surface (203) and a reference part (205) as a part of a vehicle with an electromagnetic wave; light reception parts (9, 11) for receiving a road surface reflection wave formed when the electromagnetic wave is reflected on the road surface and a reference reflection wave formed when the electromagnetic wave is reflected on the reference part; a compartment line detection part (15) for detecting a compartment line on the road surface on the basis of the road surface reflection wave; a variation calculation part (15) for calculating variation in the intensity of the reference reflection wave; and a reliability determination part (15) for determining reliability with respect to the detection result of the compartment line detection part on the basis of the variation.
