基于物体表面散乱三维激光扫描点的三角形格网建立

Triangular grid establishment based on disordered 3D laser scanning point of object surface

针对物体表面的散乱三维激光扫描点数据,提出了借助柱面坐标系统将三维激光扫描点转换为三角形格网构造系坐标,并根据转换后的坐标利用在平面内计算狄罗里三角形的方法建立三维物体表面格网模型。建立格网模型的效果表明,借助柱面坐标系统构造狄罗里三角形的方法可以作为三维物体表面三角形格网模型的一个重要的基本方法。

The cylindrical reference frame that is used for triangular grid establishment with disordered 3D laser scanning point is proposed in the paper. The method of building triangular grid model of 3D object surface with plane Delaney triangle is introduced. After collecting the surface points of the Confucius statue and the tunnel of mineshaft with 3D Laser Scanner, author realized the modeling of Confucius statue and the tunnel of mineshaft by programming. The effect of model indicates that the Delaney triangle method of constructing using cylindrical reference frame is an important basic method of constructing triangular grid model.
