Abstract: A surface-profiling system ( 20 ) and a process ( 32 ) for implementing same are presented. The system ( 20 ) incorporates a vehicle ( 40 ) configured to move upon a surface ( 24 ). A projector ( 38 ) is affixed to the vehicle ( 40 ) and configured to project two-dimensional patterns ( 22 ) at a first angle ( 52 ) substantially perpendicular to the surface ( 24 ). A camera ( 48 ) is also affixed to the vehicle ( 40 ) and configured to capture images ( 50 ) of the projected patterns ( 22 ) from a second angle ( 54 ) oblique to the surface ( 24 ) as the vehicle ( 40 ) moves over the surface ( 24 ). A computer ( 72 ) is configured to produce a transverse profile ( 26 ) of the surface ( 24 ) from each captured image ( 50 ) and configured to derive a longitudinal profile ( 28 ) of the surface ( 24 ) from a series ( 126 ) of the transverse profiles ( 26 ).
