| 摘 要： | 对传统的光点信号定位方法作了理论分析,讨论了各种方法的目标函数与优化过程。在此基础上,提出了一种基于最优加权的光点定位方法,使得像素的灰度对光点定位的贡献达到最佳。传统的方法均可看作是此方法理论框架下的特例。理论和实验表明该方法优于传统的方法。

| Abstract: | Traditional methods of light-spot positioning were analyzed so that their objective functions and the corresponding optimization processes were discovered.Based on this analysis,a novel method called optimally nonlinear weighting was proposed.In the proposed method,the contribution of each pixel was determined in the optimal manner.The proposed method provides a theoretical framework with traditional methods being special cases under this framework.This method is superior to the traditional method both in theory and practice. |
