For the hyper accuracy interpolation technique , which resolves the accuracy limitation of pixel physical size , derives out the star spot interpolation accuracy limitation based on the star spot mathematical model and photoelectric statistics 針對克服像元尺寸對測量精度限制的超精度內插細分技術,在建立了星點光斑數學模型的基礎上,利用光電統計理論,推導了星點光斑內插細分精度的極限公式。

Two kinds of interpolation algorithms are analyzed and concluded that the centroiding algorithm is better for star spot position estimation . the noise effects on the centroding are analyzed by numeric simulation , educes the noise rms model 利用誤差統計理論,采用數值模擬的方法,分析了各種噪聲對矩心法質心計算精度的影響,推導整理了噪聲誤差模型。
