Laser beams and sensors are used for measuring the exact profile, height difference and geometry of workpieces.
More focus is being put on the quality management and quality control of production processes. Manufactured products must undergo final inspection and testing. Industrial image processing is becoming an increasingly popular tool for this purpose because it is fast and highly reliable.
The light section method is a key image processing technique that is used to measure profiles, differences in height, and shapes. This technique is based on the principle of laser triangulation. A complete measurement system consists of an illumination source, a camera, and analytical software.
