A kind of detection method being suitable for mensuration cigarette tipping paper stamping area

A kind of detection method being suitable for mensuration cigarette tipping paper stamping area, it is characterized in that: by adopting two light-source illuminating system, CCD imaging system and Computer Image Processing analysis mode, thermoprint region is utilized to have properties of specular reflection, but not thermoprint region has irreflexive characteristic, by thermoprint region and non-thermoprint region segmentation out, and then calculate thermoprint region area and account for the number percent of the tipping paper total area, concrete steps are (1) sample preparation, (2) image acquisition and processing analysis, (3) result of calculation.The inventive method is by carrying out brand-new design to sample preparation, image acquisition and graphical analysis, compared with prior art there is following features and advantage: adopt two light-source illuminating system, thermoprint region is utilized to have properties of specular reflection, and the irreflexive characteristic in background area, accurately and effectively thermoprint region is extracted from background.The robotization completely of whole process implementation, effectively saves analysis time, significantly reduces the impact of human factor.
