Purpose
The purpose of this paper is to review the technology and applications of 3D visual measurement systems.
Design/methodology/approach
A particular line profile sensor is used to explain the principle of laser triangulation, and further profilers are described. A grid projection technique is presented. Finally, a series of industrial 3D vision devices from SICK are described.
Findings
3D vision is becoming as convenient as 2D as a factory integration tool. Very high‐speed laser‐scan systems are now available, making up to 35,000 profiles per second. Grid projection systems can measure to 10 μm resolution.
Originality/value
The value of this paper is to make scientists and engineers aware of advances in the practicality of 3D vision systems.
