Abstract:Through studying the relationship between space vectors of different coordinate systems, a new model of threedimensional 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.
