Abstract
A camera and a beam-scan type laser radar whose optical axes are coincident are mounted on a vehicle. A lane detector detects the vehicle's own lane on a display image by processing an image picked up by the camera. A coordinate transforming device transforms the coordinates of positional information of an object, most likely a vehicle, detected by the laser radar in conformity with coordinates on the image of the camera. Another detector compares a position of the vehicle's own lane with a position of the detected object, judges whether or not the detected object is within the vehicle's own lane, and separates the detected object within the vehicle's own lane from objects detected outside the vehicle's own lane. A failure detection method and a corresponding apparatus are provided to determine whether the optical axes of the camera and the laser radar are coincident.
