| 摘 要： | 该文主要研究了根据三维散乱点云重构管道曲面的一种算法.首先将散乱的数据点分块,计算得到对应管道曲面的中心轴线上的点,然后将其作为控制顶点拟合成光滑的B样条曲线,再以B样条上的点为圆心绘制圆,最后连接所有圆生成光滑的管道曲面.该文利用散乱点的微分几何性质及最小二乘拟合算法,局部拟合最佳的圆柱面,准确计算管道面的中心轴点,...

| Abstract: | This paper presents a method for reconstructing accurate canal surface from an unorganized point clouds.The mainly idea is that,segmenting the unorganized point clouds and computing the point on the central axis of corresponding canal surface,then setting the points as control points of B-spline and drawing a B-spline,drawing circles and center of circles being located on the B-spline,connecting all the circles to reconstruct the canal surface.This paper uses differential quantities on point clouds and the ... |
