Machine vision systems for automated inspection, sorting and parameters measurement have been focused in the manufacturing processes owing to the advantages of non-contact, high-speed and high-precision.A geometric shape recognition and geometry parameters measurement system is developed based on machine visionr.A new method of geometric shape recognition is suggested based on the integrated technologies of invariant moments, relative moments and corner detection.For geometric parameters measurement, a linear model calibration is realized to get the inner and outer parameters of camera for the actual geometric parameters.It is obtained from the experiments that the results are satisfied and the complexity of the method is greatly less than the common method which is called Hough Transform.
