D reconstruction of tree like objects is always a very interesting problem. Using the image based modeling technique, this paper presents a method of reconstructing 3D model of the tree, based on two images at different viewpoints. First, a scheme is introduced to automatically acquire the 2D skeleton data of main branches. Then, the 2D skeleton points in the two images are corresponded with the epipolar line constraint. Finally, the 3D skeleton points are reconstructed, simplified and the surface meshes of the tree are created. Experiment results show that the method presented in this paper is practical and effective.
