摘要
根据苏通大桥主梁施工期GPS实时监测系统的建立要求,为解决GPS实时、全自动监测的坐标成果至工程施工坐标系的转换问题,介绍了2种常用坐标转换模型。通过实测数据对比分析表明,采用三维空间转换模型的应用效果较好,据此设计并编程实现了该系统的坐标转换过程,运行状况稳定、可靠。
In accordance with the requirements for establishment of the GPS real-time monitoring system for main girder of Sutong Bridge at construction stage and in order to achieve solution to the transformation from coordinate results of the GPS real-time and automatic monitoring to the local grid coordinate system of engineering construction, two kinds of commonly-used models for coordinate transformation are introduced. The comparative analysis of field measurement data indicates that the effect of utilization of the 3-dimensional coordinate transformation model is rather good and according to the model, the coordinate transformation of the GPS real-time monitoring system is designed, programmed, realized and the transformation works normally and reliably.
