ON-VEHICLE OBJECT DETECTION DEVICE

An object of the present invention is to provide an on-vehicle object detection device, which achieves both reduction of the load of image processing and reduction of erroneous detection of non-solid objects. A processing candidate Q is selected based on the distance from an own vehicle 70 to an object P, and a forward-view image 60 of the own vehicle 70. Then, based on the distance to the selected processing candidate Q, and the forward-view image 60, it is determined whether or not the processing candidate Q is a predetermined solid object P1 which is set in advance. This reduces the number of executions of the processing for determining the solid object P1, which has a heavy processing load, and also reduces the processing load of a device 3. Further, the solid object P1 is determined by image-processing a high-resolution image, and thereby erroneous detections are reduced.
