Abstract
Provided is an object detection device capable of reliably recognizing a vehicle. This object detection device detects multiple three-dimensional objects from a left image and a right image captured with a left imaging unit and a right imaging unit (S), extracts, as combination candidates from among the multiple three-dimensional objects, two three-dimensional objects which exist with an interval to the left/right, and determines whether a sparse parallax region, which is a region having a smaller parallax density than left/right regions, exists in an intermediate region between the two three-dimensional objects extracted as combination candidates. Then, the regions of two three-dimensional objects (for which it has been determined that a sparse parallax region exists in the intermediate region, and which have tentatively been identified as a single three-dimensional object) are extracted respectively from the left and right images and compared to each other, a determination is made regarding whether the perspective is the same, and when it is determined that the perspective is the same, the two three-dimensional objects are determined to be a single three-dimensional object.
