本文就如何测绘圆形建筑物平面图形的问题,作者提出了两种计算方法,即极坐标测绘法和直角坐标法;并推导出了用这两种方法计算圆心位置和半径的公式。
In this paper, on the issue of how to map the circular building’s plane figure, the author proposes two kinds of calculation methods, namely the polar coordinate survey method and the Cartesian coordinate method; and the formula for calculating the center and the radius of the center of the circle using these two methods is deduced.
