【摘要】 随着光电测距仪的广泛使用,极坐标法已逐渐成为高等级公路曲线测设的一种简便、迅速、精确的方法。本文运用误差椭圆理论,对光电测距仪在各种置镜点上,以极坐标法测设曲线的点位精度进行了分析研究和比较。更多还原

【Abstract】 With the extensive application of the electro-optical range finders, the polar coordinate method is used as an easy, rapid and exact method for the curve survey of the high class highways. This paper analyzes the accuracy of the electro-optical range finders setted at various statios using the error-llipse theory. The point accuracy of the curve survey the polar coordinate method is also analyzed in this paper.更多还原
