图像处理中圆心算法研究

Arithmetic of Computing Center of Circle in Computer Image Processing

根据计算机处理中求取高精度圆心的要求,对计算机处理图像圆心的多种算法进行研究和比较,分析产生误差的来源和解决的方法,提出采用约束条件预处理的最小二乘计算圆心的方法。采用径向误差作为约束条件选择有效的图像边界点,既可避免不必要的计算,又提高了精度,是一种准确有效的算法。

In order to solve the problem of computing center of circle with high precision,this paper discusses the processing of image circle, a least square arithmetic of computing the center of circle with restrained condition is presented. The approach of choosing available dots with restrained condition is not only for avoiding the unnecessary accounting but also for improving processing precision.
