中文摘要：

为线片断的不确定性模型的数学理论被总结完成一个一般概念，并且ε_σ 的线错误乐队模型是当ε_ m 和错误熵的模型能被认为是它的补充时，能高效地描绘线精确性和质量的一个基本不确定性模型。错误乐队模型将在多角形不确定性上反映并且描述线不确定性的影响。因此，线错误的统计特征被分析线错误掉进的概率深深地学习某个范围。而且，理论一致在选择被完成为线特征的错误缓冲区和错误指示物。为有为一条多角形边界的错误环的一个多角形的区域的精确性的关系被推出并且计算。

英文摘要：

The mathematic theory for uncertainty model of line segment are summed up to achieve a general conception, and the line error hand model of εσ is a basic uncertainty model that can depict the line accuracy and quality efficiently while the model of εm and error entropy can be regarded as the supplement of it. The error band model will reflect and describe the influence of line uncertainty on polygon uncertainty. Therefore, the statistical characteristic of the line error is studied deeply by analyzing the probability that the line error falls into a certain range. Moreover, the theory accordance is achieved in the selecting the error buffer for line feature and the error indicator. The relationship of the accuracy of area for a polygon with the error loop for a polygon boundary is deduced and computed.
