摘要
从空间几何角度出发,利用空间向量的关系研究坐标转换,提出一种新的三维基准转换模型。通过模拟算例和在工程中的实际应用证明:该模型不受坐标转换旋转角大小的约束,能适用于任意角度;计算结果可靠,精度较高,与现有模型相比,有着简便、效率高的特点。
Through studying the relationship between space vectors of different coordinate systems, a new model of three-dimensional datum transformation is proposed. Taking a simulation example, the comparison between this model and a traditional model proves that this model can simplify the complex calculation of traditional models and is suitable for any rotation angle. Besides, a project example is given to illustrate the reliability and feasibility of this model.
