Abstract
The purpose of the present invention is to provide an onboard environment recognition device exhibiting high accuracy of measurement in a wider range of view fields. The present invention pertains to an onboard environment recognition device () that utilizes two cameras () for sensing, wherein the onboard environment recognition device () is characterized in that: two camera view fields include a stereo-vision area and a monocular-vision area; and the device laterally searches for parallax images that are output results of the stereo-vision area, estimates a road surface distance in the stereo-vision area, and measures the distance of the monocular-vision area by using the estimated road surface distance after extending the same to the monocular-vision area in the lateral direction.
