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。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 eases under this framework. This method is superior to the traditional method both in theory and practice.
