| 摘 要： | 54北京坐标系与80西安坐标系转换计算，属54系与80系不同参考椭球下高斯—克吕格投影数据转换计算，因全国不同区域重力场的变化而无法用一个固定的参数或公式推算，能否另辟途径实现其精确算法。应用多元统计分析基础理论，研究二者互换随机数学模型，以福建省区域为例，成功实现大批数据坐标转换。

| Abstract: | Because of the varieties of different regional gravitational fields in whole country, there are no fixed parameters and formula in the conversion of the 54 Beijing Coordinate System and 80 Xi'an Coordinate System.The paper introduces a mathematics conversion model of the accurate calculation of conversion values. The model is based on the multiple statistical and analysis basic theory and the analysis results of the random mathematics conversion models of two coordinate systems. According to the model, a batch of coordinate data can be transformed successfully. The paper presents the conversion results of two coordinate systems in Fujian Province by using the about-mentioned mathematics conversion model. |
