瞳孔直径估算模型
|
摘要
在对已有瞳孔直径估算模型研究分析的基础上,测量了不同光环境下受试者瞳孔直径的变化,利用实测数据对现有模型进行了对比分析。利用角膜通量密度建立了亮度、视角与瞳孔直径的关系,并以Stanley-Davies模型为基础对原有计算关系式进行了修正与优化,提高了模型的计算精度。通过实验拓展了Stanley-Davies计算方法的适用视场范围,将最大适用视场拓展到40°。
On the basis of the analysis of the existing pupil diameter estimation models, the changes in pupil diameter of all subjects under different light environments are measured. The comparison among all existing models are made by use of the measurement data. The relationship of luminance and visual angle with pupil diameter is established according to the corneal flux density. Moreover, based on the Stanley-Davies model, the original calculation formulas are corrected and optimized, and thus the calculation precision of this model is improved. Via experiments, the field of view area is extended and the maximum field of view is increased to 40 degrees.
