在外业测量中,尤其工程测量,所放样的两测量坐标点通常距离很远,这样我们就需要在其两控制点之间加密控制点,能有效的高精度的控制工程单体位置,有时我们内业已经计算好的控制点坐标在实地放不了(如水沟、障碍物等),这样我们都需要从新计算坐标。下面阐述已经有了已知两控制点,简单计算出其已知两控制点直线上的任意我们想要的放样点坐标值。 In field surveying, especially engineering surveying, the two survey coordinate points are usually far away from each other, so we need to encrypt the control point between two control points, which can effectively control the position of the engineering monomer with high accuracy. Sometimes we The coordinates of the control points already calculated in the field can not be put on the ground (such as ditches, obstacles, etc.) so that we all need to calculate the coordinates from the new one. Explained below already has two known control points, simply calculate the coordinates of any point we want to know the coordinates of the two control points on the line.
