For the quality inspection K+P uses industrial image processing, with which devices are used, which capture, analyze and evaluate visual information. By means of these systems test procedures can be automated, otherwise a "human eye" would require. Image processing systems consist of a lighting and an image sensor, which captures images digitally and analyzes it by means of a so-called vision software. The resulting information can be now evaluated automatically and transferred to another device (e.g. PLC or PC). The recorded images can be displayed on a screen and quality problems can be represented for the employees. Vision systems are available in various designs, from PC-based systems to intelligent vision sensors.
