THREE-DIMENSIONAL OBJECT DETECTION DEVICE, AND THREE-DIMENSIONAL OBJECT DETECTION METHOD

摘要

The present invention is provided with: a camera (10) for imaging the rear of a vehicle; a three-dimensional object detection unit (33) for detecting a three-dimensional object at the rear of the vehicle on the basis of the acquired image; a lens cleaning device (100) for cleaning the lens (11) of the camera (10) by using a cleaning solution in accordance with a predetermined lens cleaning process; a lens state determination unit (38) for determining whether the state of the lens (11) is in a predetermined state to be controlled on the basis of the timing at which the cleaning solution is sprayed on the lens in the lens cleaning process; and a control unit (39) for preventing a three-dimensional object from becoming detected by suspending the detection immediately before it is determined that the lens state is in the state to be controlled or by retaining the aforementioned determination result for a predetermined time when it was determined that the lens state is in the state to be controlled.
