3D Machine Vision Using Laser Triangulation

摘要

Laser triangulation is a flexible approach that is often the best solution to the growing need for 3D vision for process monitoring in numerous industries. While a laser line generator and camera is the simplest and most common implementation, the uniformity of the line is not a trivial consideration; it determines the quality of the data. This, in turn, strongly depends on the type of beam shaping optics used, which must be matched to the specifications and budget of the particular application.
