Study on CCD Measurement System Based on Image Processing
Zhao Wen, Zhen Yun Duan, Ping Zhao, Wen Zhen Zhao · Advanced materials research · 2012
The measurement system based on industry CCD and image processing was established to measure 2D sizes of parts. The CCD sensors, lenses, illumination and image acquisition modes were chosen to establish hardware part, according to the requirement of views and precision. The software system was developed to extract the edge of the part from the digital image and transform it to a polynomial. The actual sizes of the part were measured with relative comparison calibrating method. Tests and analyses show that it is an untouched, automatic 2D Measurement system with high accuracy.
