To record height profiles, we use the Cognex In-Sight laser profiler. This system allows complex measurements and inspections of profiles and surfaces along a line. In contrast to conventional cameras, the height profile here is generated by a laser profile cut along the height of the component. Thus, the height information of the surface along the laser line of the considered workpiece is obtained.
Based on this information, various measurement and testing tasks can be performed. Evaluation is carried out via a VC200 Vision controller, to which up to two laser heads can be connected. For example, this controller can be connected to a higher-level control system via PROFINET. The measurement results are visualised via HMI and in a web browser.
