Automated detection of surface defects on power transmission belts

Development of a new method for an automated detection of surface defects on synchronous belts is presented and demonstrated on a group of samples with typical surface defects. Three-dimensional shape of the belt teeth is initially measured by a laser scanning system and further processed using a novel approach based on deviation map analysis. A deviation map shows deviations between the measured surface and a predefined reference surface of the tooth. Defects are detected and classified on the base of the deviation parameters calculated from the deviation map. The developed method produces results that correspond well with the results of the visual inspection.
