Smart cameras tackle 3D industrial inspection

Abstract

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.
