Triangular grid establishment based on disordered 3D laser scanning point of object surface
Yuntao Zhang · Engineering of Surveying and Mapping · 2004
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.
