【Abstract】 An electrv-optical measurement procedure based on CCD average output to aimoptical edges is described in this paper. The system, with the grating as measuring unit and themoving platform as scanning unit. can be used to measure optieal code lines automatically, especially for the measurement of satellite’ optical code plates.更多还原
