摘要：

In　order　to　detect　the　overprint　deviation　in　color　printing,　the　article　brought　forward　a　method　based　on　computer　vision　and　established　its　algorithm.　The　image　of　the　measuring　mark　of　plate　captured　by　CCD,　recognized　and　analyzed　the　registered　mark　by　the　statistic　character　of　hue　in　HSI　space,　and　segmented　the　color　image　by　the　2　paramaters　of　hue　and　intensity,　measuring　data　about　the　registering　quality　can　be　obtained　by　hue　projecting　integral　method　after　color　image　segmentation.　Experimental　results　show　that　the　system　can　fast　enough　measure　the　exact　overprint　deviation　in　color　printing　and　have　used　to　examine　the　overprint　precision　in　Beiren　Printing　Machinery　Co.,　Ltd.
