基于稀疏点云的树木三维重建软件使用说明

树点云三维重建

在基于稀疏点云的树木三维重建软件中,选定输入点云数据后,用户可以在参数栏中设置不同参数值,控制树干生长角度,树枝密度,树枝光滑度等,可以对树干和树叶选择不同的颜色。软件中预置了不同树叶模型供用户选择,通过调整参数,可将树木模型调整的更真实。以下为软件使用过程展示。

步骤1: 打开Software文件夹,双击可执行程序3DTreeModelGen.exe,在Models栏目后选择导出的树木点云文件,进行模型重建。软件可通过 'W','A'键控制俯仰角, 'S','D' 键控制左右旋转,'Q','E'键控制左倾右倾角度,'Z','X' 键控制缩放。

步骤2:
  1. 在图2红色框内设置不同的参数值,控制树干生长,点击Reconstruct tree重建树木(图2)。

2. 在Tree control的栏目中手动调整树枝模型粗度以及叶片大小、密度等参数,可将模型调整的更具真实感(图3)。

3. 在Tree control的子栏目Leaf models中选取不同的叶片模型,使得重建出的树木模型具有不同风格。图4为枫叶模型对应的重建效果。
