The Measurement of Small Cylindrical Pieces Based on Digital Image Processing
This paper establishes a monitoring system suitable for online measurement of dimentional parametres of small cylindrical pieces. The system ,which is based on digital image processing ,consists of optical light sources, a CCD camera, PC, and MATLAB digital image processing toolbox. The image acquired by CCD is pre-processed through the procedure of image gray enhancement, image equalization, image binarization and dimentional parameters extraction interface to achieve online measurement. The smallest rectangle method is used to obtain the dimentional parameters. An automatic detection interface of dimentional parameters measurement based on MATLAB is compiled which can provide a solid foundation for the online and fast detection of dimentional parameters based on image processing technology.
