船体分段测量点数据与CAD模型自动匹配方法研究OA北大核心CSCDCSTPCD
Methods of automatically matching measurment points data with CAD model for hull blocks
为了能准确分析船体分段的建造误差,给出合理的建造精度评价,船体分段测量点数据与CAD模型的精准匹配是关键.针对目前船厂通常采用全站仪进行测量,提出一种以全站仪测得的船体分段测量点集为处理对象,自动进行测量点数据与CAD模型匹配的算法.该算法分粗匹配与精匹配两部分,粗匹配采用主元分析(PCA)法来缩小测量点集与CAD模型点集间的错位,通过搜索最近点法来确定对应点对；精匹配以粗匹配的结果作为初始位置,采用欧拉旋转理论对测量点集进行旋转和平移调整使匹配…查看全部>>
Precise matching of measurement data with a CAD model for hull blocks is the key to accurately analyze construction errors and rationally evaluate construction precision. An algorithm to automatically match measurement data with a CAD model was proposed. The measurement data was measured by a total station which is currently used in shipyards. The algorithm was divided into two steps. One was rough matching and the other was precise matching. Rough matching …查看全部>>
