Abstract
A vehicle-installed obstacle detection apparatus includes a forward-view camera, and processes resultant image data to detect objects as possible obstacles. A size value such as tail lamp spacing, transmitted from a preceding vehicle, and a corresponding size value as measured in a captured image, are used to calculate the distance of the preceding vehicle. This is used together with a height value transmitted from the preceding vehicle and a corresponding height value measured in the captured image, to calculate the relative height difference between the vehicles, which is then used to discriminate between detected objects which are actual obstacles and objects such as road surface markers.
