This　paper　introduces　a　new　correction　method　for　laser　scanner　system.　Based　on　image　recognition,　the　laser　marking　result　which　includes　a　crossed　matrix　is　grabbed　as　matching　pattern.　A　algorithm　is　presented　to　locate　all　crosses　and　measure　their　positions,　and　a　correction　data　is　generated　automatically　for　laser　scanner　system.　This　method　makes　the　correcting　process　be　much　faster　and　more　accurate　than　conventional　manual　measurement　way.
