6 CONCLUSIONS
The Biris system has demonstrated that it is capable of range data recovery from a variety of common surfaces
encountered in an industrial setting. Whilst its short baseline configuration means that it will never be capable of
millimetric precision over 2-3m stand-off distances it does, never-the-less, enable surface recovery with similar
precision to those quoted by the manufacturers of time-of-flight systems. It's compact, robust construction together with
lightweight means that such a system would form a very useful additions to the industrial surveyors toolbox.
The recovery of geometric entities from these range images still remains a semi-automatic task. However, the random-
sampling strategy describe appears very robust to the noise typically found in such systems when used on a wide variety
of surfaces. With the ever-increasing power of desktop computers such ‘brute-force’ strategies offer considerable
potential for further development.
