ABSTRACT:
A monitoring apparatus for monitoring the periphery of a motor vehicle in which patterns painted on the surface of a road are eliminated to shorten a time required for calculation to determine a position of a subject by processing image data generated by two cameras, whereby image data of the object having a height is derived by subtracting image data generated one camera from image data generating by the other camera after transferring either of image data to the other image coordinate by assuming that the transferring image data have a height of zero (0) for canceling road surface images and sounding an alarm whenever it is determined that the position of the object causes an obstacle of the moving vehicle.
