摘要
提出一种基于数字图像技术的零件尺寸的测量方法,从数字图像测量系统的建立、图像预处理、直线的Hough变换、圆的最小二乘法拟合、亚象素定位、系统标定等几个方面进行探讨,给出测量方法。从理论上和实践上证明本方法的可行性和正确性。
The article introduces a measurement method of mechanical parts based on digital image process. Through the establish of digital image measurement system, image processing, Hough transform of line, least-square fitting of circle, sub-pixel locating and system demarcating, giving the measurement method and practice, proves the feasibility and exactness of this method on the theory and practice.
