　　树木的形态结构可视化是当前计算机图形学的难点之一。本文以杉木为例，提出基于图像的造型方法，实现对树木的形态结构的三维重建。具体做法是：首先，用单数码相机拍摄两幅图像，从图像上提取树木主干的相关信息(主要包括树高、根径和胸径等参数)；然后，分析实测数据，得到树木的分枝信息；最后，结合两组信息重建树木的形态结构。

　　Morphology visualization of the trees is one of the difficulties of the current computer graphics.In this paper,we put forward an image-based modeling method to come true the 3D reconstruction of the morphological structure of the trees.First,shooting two images with a single digital camera and extracting the relevant information (including tree height,root diameter diameter at breast height,and other parameters) on the tree trunk from the images.Then,analyze the measured data for get the information of the branches of trees.Finally,combine two sets of inform...
