Abstract
An object detection apparatus measures a distance to a detected object at each irradiation angle, based on reflected waves of electromagnetic waves irradiated from a laser light irradiating unit at each irradiation angle. The apparatus determines whether the measured distance remains unchanged for prescribed period of time, for each irradiation angle, and stores the determined distance in a storage unit as a stationary object distance in association with the irradiation angle. The apparatus compares the current measured distance and the stored distances, and determines whether a stationary object distance matching the current distance is present among the stored distances. The apparatus initially compares the shortest stationary object distance among the stored distances with the current distance, and upon determining that a stationary object distance matching the current distance is present, stops the comparison of the current distance and the stored distances that have not been compared with the current distance.
