| Abstract: | A new center positioning algorithm of circular mark was put forward,which can fit the ellipse parameters by nonlinear least squares.It improved the ellipse edge detection method in the sub-pixel positioning algorithm.Moreover the estimating formula for mark location uncertainty was derived,and confidence interval in a certain confidence level was calculated by use of the Monte Carlo integration.An example certificates that the new location algorithm can achieve about 0.02 pixel positioning accuracy which ri... |
