植物叶片是植物最重要的器官之一，重建高精度的叶片模型对于后续研究具有重要意义。但由于室外椭圆形树叶的点云数据存在噪声和树叶边缘不光顺等问题，所以不易重建出高精度的叶片模型。本项研究提出了一种针对室外椭圆形植物叶片重建的方法。该方法首先根据噪声点特性和扫描线特性，对点云数据去噪。然后根据每条扫描线的端点，拟合出光顺的树叶边缘。最后采用三角剖分方法生成网格。实验结果表明该方法能够根据激光点云数据快速重建出椭圆形植物叶片的高精度模型。

Since leaf is one of most important organs of a plant , high-precision reconstruction model of oval leaf has significant meaning for further research.However , it is difficult to be reconstructed it due to be reconstructed noises and leaf edge which may not be smooth in the real point clouds data.A reconstruction method for out-door o-val plant leaves is proposed in this paper , and it is composed of de-noise processing of laser point cloud , fitting leaf edge , and Delaunay triangulation for generating mesh surface.The results of its test showed that this proposed method could quickly reconstruct high-precision model of oval plant leaves based on laser point clouds data.
