Research on Thickness Measurement of Transparent Object Based on CCD Vision System

Novel thickness measurement of transparent object based on line-structured laser and CCD vision technique is present in this paper. The measurement of light stripe image distance is transformed from the measurement of thickness. This article focuses on the experiment design, and the factors that influence accuracy of measurement are discussed as well. The research with positive laboratory verification has proven the feasibility and validity of photoelectric measurement of transparent object thickness. The resolution of thickness measurement can be 8.2 mum.
