摘　　要：为了真实虚拟黄瓜叶片形态和叶片纹理,实现黄瓜的动态生长三维虚拟,提出了用图像处理提取黄瓜叶片边缘特征点进行叶表面重建,借助粒子系统思想构造叶片纹理并与叶表面合成的叶片三维重建方法,用曲面投影法实现叶片的弯曲变形。结果表明,该方法较好地保持了黄瓜叶片边缘形状,真实地反映了叶片纹理的细节特征以及叶片在空间的弯曲变形。A 3D reconstruction method of cucumber leaf is presented to simulate the morphology and texture of leaf veritably and implement 3D virtual dynamic growing of cucumber leaf.The reconstruction was implemented by employing image processing method to extract cucumber leaf edge data based on which leaf surface was reconstructed using triangle faces and employing the thought of particle system to model leaf texture.Furthermore,leaf surface and leaf texture was synthesized and bended by projecting them to curved surface based on the method.The results show that the method keeps the natural edge shape of leaf,reflects the detail character of leaf texture actually and works well on simulating bending deformation of leaf in space.
