同心圆拟合法在海洋钢结构测量中的应用

Application of Concentric Circle Fitting Method in Offshore Steel Structure Surveying

在海洋钢结构测量中,圆管端部坐标是需要精确控制的重要位置之一。为提高圆管杆件的端面圆心的测量精度,提出一种同心圆拟合法。算法同时加入圆管内皮和外皮测量点坐标数据,较传统方法增加了测量点数量,而且测量点分布更广更合理,大大提高了圆心的精度。

In offshore steel structure surveying,the coordinate of pipe end is one of the most important positions which should be controlled accurately.In order to improve the accuracy of the circle center at the pipe end,a new method,the concentric circle fitting method,is introduced in this paper.With the coordinate data of survey points both inside and outside the pipe wall added to the algorithm,the method has more survey points with more extensive and reasonable distribution than the traditional method,thus greatly improving the accuracy of the circle center.
