Abstract

An apparatus and process for automatic error recognition for testing for tears in a magnetic-powder process during in-process control of image processing, whereby image recording units together with a downstream image processing unit evaluate areas with different optical characteristics from selected sample surface segments. In the process, a robot gasps at least one of the passing samples in precise position and brings the sample into a three-dimensional testing apparatus with image recording units arranged three-dimensionally, whereby the robot places the sample in precise position into the three-dimensional testing apparatus. The sample is then photographed by the image recording units which then transmit the obtained image information to a computer for evaluation. This computer is able to direct the robot accordingly based on its evaluation.
