摘要
应用误差椭圆的基本理论 ,由两个任意方向的位差和协方差导出了计算任意方向位差的基本公式 ,并以此为基础 ,非常简洁而新颖地得出了前方交会、侧方交会、后方交会、单三角形和测边交会点在任意方向上的位差和点位误差的公式。这对于交会点误差估算的理论和实用都有较大的意义。
Through displacement error and mutual square error of any two directions, the author gives a general formula of displacement error of any direction by using basic theory of error ellipse. Meanwhile, it also gives the formula of displacement error and point error of any directions in forward intersection, lateral intersection, three point intersection and sides intersectional point. This helps understanding the theory and application of intersection point error estimate.
