Arithmetic of Coordination Transformation Parameters of Big Rotation Angle based on Bursa Model

在布尔萨模型基础上提出了一种适合大旋转角三维直角坐标转换的方法,解决了传统方法中的线性模型不适合大旋转角的问题。该算法具有计算简便、收敛速度快、不依赖转换参数初值、便于程序实现等特点。并通过模拟算例验证了该方法的正确性。

This paper puts forward a method adapting to big-rotation-angle 3D rectangular coordination transformation based on BURSA model.It resolves the problems that the conventional linear model is unsuitabal for big-rotation-angle 3D coordination transformation.This arithmetic has many characteristics,such as calculating simply,converging rapidly,not relying on the initial values of 7 transformation parameters,faciliting program realization.A simulation example proves its validity.
