Abstract
A first light projector projects first slit light that spreads in the width direction of a vehicle in a direction other than a direction parallel to a contact ground surface. A second light projector projects second slit light that spreads in the width direction of the vehicle in a direction parallel to the contact ground surface. An obstacle detection unit detects an obstacle using a captured image of an area surrounding the vehicle where the first slit light and the second slit light are projected.
