Abstract

An apparatus and method for indicating a contour of a surface relative to a vehicle, in which a first electromagnetic radiation source projects a first beam to create a first reflection pattern on the surface. A second electromagnetic radiation source projects a second beam to create a second reflection pattern on the surface. An apparatus is provided for coupling the first and second electromagnetic radiation sources to the vehicle, such that a movement of the vehicle results in a movement of the first and second reflection patterns on the surface.
