决定一个线片断的位置的错误的分发, MonteCarlo 途径被使用与在一个线片断的端点的错误跟随的假设模仿一个线片断的概率密度功能二维的正常分布。为如此的目的,与 thetwo 维的正常分布为不明确的端点使用的一个随机的发电机被介绍。这为一个整个线片断的错误模型的模拟形成随机的线片断的产生的基础。错误模型盖住二个端点对对方独立或依赖的盒子,也包括在在一根线的二个随机的端点之间的距离分割的一种特殊情况是足够靠近的。
To determine the distribution of positional error of a line segment, Monte Carlo approach is applied to simulate the probability density function of a line segment with the assumption that the error of endpoints in a line segment follows a two-dimensional normal distribution. For such purpose, a stochastic generator used for uncertain endpoints with the two-dimensional normal distribution is presented. This forms the basis of the generation of random line segment for the simulation of the error model of a whole line segment. The error models cover the cases where two endpoints are either independent or dependent to each other, also including a special case that the distance between two random endpoints in a line segment is close enough.
