摘　　要：介绍了海洋结构物建造过程中的常用测量方法,着重介绍了三维测量过程中数据匹配的原理。采用VB6.0语言编制了海洋结构物三维测量的误差检验程序,程序通过坐标变换和优化算法可以实现测量点坐标位置与设计点坐标位置的最佳匹配,并给出最佳匹配状态下各关键点的误差值;同时,根据坐标变换关系可以对区域进行误差预报,为今后实现大型海洋结构物高精度化建造提供了参考。In this paper, an introduction is presented to describe common measuring methods for marine structure construction with the principle of mentioned data matching especially. Based on relevant theory, an error checking program for spatial measurement of marine structure is developed and written in VB 6.0, which enables to achieve optimal matching between the coordinate position of measurement and the one at design point, while error value at each key point under optimal matching states is given using methods of coordinate transformation and optimization algorithm. Meanwhile, errors in certain regions can be forecasted according to the coordinate transformation principle, which may benefit and provide references for the construction of large marine structure with high precision in the future.
