Abstract

For the PCB inspection by computer vision, in some cases, the MRLC file should prepared. The MRLC file contains a RLC(Run Length Code) and a direction flag. In this paper, a generating method of MRLC is described. It is composed of two procedure as followings; (i) rasterizing Gerber file which is a vectorized image of PCB panel, and (ii) calculating a MRLC that is useful for the inspection as a template image. The suggested procedures are written in C-language and executable on Windows 95 and Windows NT.
