摘要：Recent developments in non-contact industrial range imaging systems have generally focussed either on very high- precision, short range, active triangulation systems capable of detailing measurement volumes of a few sq uare metres or medium precision, time-of-flight systems with typical standoff distances of 2-50 metres. This paper will highlight a range of applications for medium precision (+/- 5mm) imaging of relatively complex, room-sized environments which are not currently well served by such systems. It will also suggest that the development of relatively short baseline active triangulation systems may lead to affordable, compact and robust short-range measurement systems capable of delivering range data suitable for such applications. A brief review of current systems for non-contact range-imaging will be followed by a detailed discussion of system trials undertaken with a modified Biris triangulation system in a typical engineering environment containing a wide variety industrial surfaces with a range of surface reflectivity characteristics. The authors will conclude that such a system may offer a compact and flexible alternative to competing technologies that could be readily deployed in co mplex small-scale industrial settings
