坐标基准转换可通过空间的三参数和七参数及平面相似变换等方法实现。其中,七参数法最为常见。本文将对二维七参数模型的精度进行验证,并将二维七参数模型与标准七参数模型进行比较研究。
Coordinate reference transformation can be achieved by means of three parameters of space and seven similar parameters and plane similarity transformation. Among them, the seven-parameter method is the most common. This article will verify the accuracy of the two-dimensional seven-parameter model and compare the two-dimensional seven-parameter model with the standard seven-parameter model.
