Paper Abstract

The optical system proposed combines together the axial motion technique (where the camera remains motionless during the experiment measuring absolute range) with the triangulation technique giving relative range with respect to a reference point. The characteristics of this optical system, such as standoff distance and range resolution, are theoretically determined. Experimental results are shown for ranges varying from 50 cm to 1.50 m with a depth resolution increasing from 1 mm to approximately 10 mm.
