Abstract
The purpose of the present invention is to enable precise calculation of the distance to a moving object that is detected in a monocular area even in the case where the road height varies between an overlapping area and the monocular area. According to the present invention, provided are a parallax-information obtaining unit that obtains parallax information about an overlapping area of a plurality of images captured by a plurality of cameras installed in a vehicle; and an object-distance calculating unit that calculates the distance between an object detected in a non-overlapping area and the vehicle, the non-overlapping area being an area other than the overlapping area in the images, on the basis of parallax information obtained from the overlapping area in the past.
