The establishment and application of measuring software system of coordinates

在测量软件中,坐标系的建立是后续测量和评价的基础。从坐标系建立原理出发,深入讨论了测量行业应用坐标系的理论方法,分析了测量行业的坐标系转换模型,并建立了矩阵理论模型,给出了矩阵理论公式。首先,按照测量软件功能对不同环境下的坐标系进行分类,深入分析不同类型坐标系的应用方法;其次,论述了不同坐标系的关系,按此分类搭建起软件合理的坐标系系统;最后,以模型坐标系为例,给出了坐标系数据的两种不同应用方式,以及不同方式产生数据的具体处理办法。按照所述原理和方法,可快速、高效地搭建测量软件的坐标系处理系统,对搭建类似CAD系统软件的坐标系模块有积极的借鉴作用。

In measuring software, the establishment of coordinate system is the foundation of the successive measurement and evaluation. Based on the principle of coordinate system, the theory and the method of measuring coordinate system in industrial application are deeply discussed in this paper. We make a deep analysis on the coordinate transformation model in measuring, and present a formula of matrix theory. In this paper, firstly, the coordinate systems in different settings are classified according to the functions of the measuring software, comparing the ap- plication methods of different kinds of coordinate system. Then the relationship in the different coordinate systems is discussed, and the reason- able coordinate system is built based on the classification. Finally, taking the model coordinate system as an example, the two different applications of the coordinate data are presented, as well as the corresponding specific data processing method it generates. In accordance with the principle and method proposed in this paper, a coordinate measuring software processing system could be quickly and efficiently built. It could be used for a reference for the development of other analogous CAD system.
