摘要
根据信息论基本原理,提出了二维随机点的熵误差指标。该指标与以往的误差指标不同,它是一个在熵意义下唯一确定的、与置信概率无关的客观指标。把它作为二维点位置不确定性的度量指标具有特殊优越性。
A new error index is bought up on the basis of united entrop in the paper.This index is different from existing other standard,such as CSE,CPE,CMAS and so on,and independent of a certain confidence limit and very suitable to uncertainy measure standard.
