Abstract

This paper discusses some accuracy related problems of a vision inspection system which were studied in developing such a system for a drill inspection. A structured illumination device was designed to obtain high quality image of a drill. The errors in image conversion was studied and it was found that the variation of the illumination intensity changed the dimension of the parts due to the quantization effect of the digital computer. A CCD linear array based light monitoring system was proposed to provide the information about the light distribution of the image. Several possible control schemes upon the output of the monitoring system are discussed.
