Abstract: ILC-HiGrade-Report 16 pp., (2013).<br />A high resolution camera and sophisticated illumination system has been mountedin a robot that facilitates the acquisition of images of the inner surface of superconductingcavities, which otherwise are hardly accessible. The OBACHT (OpticalBench for Automated Cavity inspection with High resolution images on shortTimescales) system in use at DESY has been optimized for acquisition time andresolution. This note describes the algorithms used to recognize the characteristicwelding seam and adjust the focus.
