1. An object detection and ranging method for a motor vehicle, comprising the steps of: providing an imaging device; providing a data processor for interpreting a captured image of a field of interest provided by the imaging device; processing rows of pixels; comparing pixel data collected by said data processor to a pixel map of one or more surfaces to filter out and discard said surfaces; and reporting a real world translation to a vehicle operator, wherein said real world translation includes at least object dimensions and distance from the vehicle for all objects in said field of interest; wherein processing said rows further comprises a morphological erosion filter for filtering out and discarding pixel noise.
