This　paper　introduces　a　solution　for　laser　scanning　system,　which　utilizes　machine　vision　technology.　It　includes　algorithm　for　positioning　and　matrix　for　scanning　control.　The　system　can　be　used　to　detect　an　object　and　laser　mark　on　specific　position.　This　work　explains　how　to　use　one　CCD　to　catch　an　object＇s　position　variation　relative　to　a　reference　point,　and　how　to　translate　the　different　coordination　systems　for　laser　scanner　etc.
