摘要
在道路工程测量中,直线坐标方位角反算是最基础的计算之一。从向量观点出发,通过借助向量内积、外积,推导出反余弦函数计算坐标方位角的方法。该推导过程直观形象,易于理解和掌握,为计算坐标方位角提供了一种新思路,具有重要的参考价值。
In road engineering survey, the inverse calculation of the linear coordinate azimuth is one of the most basic calculations. From the viewpoint of vector, by using vector internal and external product, the calculation method of co?ordinate azimuth was derived by computing the inverse cosine function. The derivation process was visual and easy to understand and master. A new idea was provided for calculating coordinate azimuth. The research is of great referen?tial value.
