| 摘 要： | 精确的植物三维形态结构模型可用来研究与植物空间结构相关的性质,是虚拟植物、植物建模等相关研究的一个重要方面。该文主要研究了采用基于结构光技术的三维信息采集系统,结合必要的旋转装置,快速无损地获取植物点云数据,从而获取植物三维形态结构的方法。为解决这种三维信息采集时点云数据无法良好配准的问题,该文提出了一种基于改进的外部附加结构的配准技术,使得配准精度、稳定性及处理速度都有显著提高。该研究结果可为深入研究植物虚拟生长建模技术奠定良好的基础。

| Abstract: | Plant three-dimensional information acquisition technology can accurately reproduce the morphology of specific plants, and can be used to study the spatial structure related properties of plants. The paper mainly studied how to obtain complete plant point cloud data by using a three-dimensional data acquisition system and rotating device, and then to obtain the three-dimensional information of plant spatial entities quickly and non-destructively. A rectification technology was proposed based on external additional structure, which partly solved the problem that the point cloud cannot be registered well. The results can provide a reference for the modeling technology of the virtual plants growth. |
