Vehicle-mounted control device, and three-dimensional information acquisition method

Abstract

To provide a vehicle-mounted control device that suppress a ranging error by controlling an imaging start timing of a rolling-shutter type camera according to a situation when acquiring the three-dimensional information around the vehicle based on a pair of still images captured by a pair of the cameras including at least one rolling-shutter type camera. The vehicle-mounted control device communicates with a plurality of cameras including a first camera with a rolling-shutter type image sensor. The vehicle-mounted control device includes: a ranging unit that measures a distance to a ranging target using a plurality of images captured with a first camera and a second camera, the second camera being capable of capturing a same ranging target in at least part of an image capturing region of the first camera; and an exposure timing adjusting unit that adjusts an exposure timing of at least one of the first camera or the second camera based on a ranging position of at least one of the plurality of images.
