由于现阶段对于花朵三维点云的特征提取研究还不充足,以及三维点云数据的无序性,文章旨在提出一种基于圆柱坐标系的花朵点云特征提取方法,以单个百合花点云数据为研究对象,利用圆柱坐标系的半径、角度和高度等参数来建立与点云中点之间的拓扑关系,从而更好地进行点云特征提取。经实验分析,该方法能有效提取出百合花朵点云的6个花瓣和1个花心特征,极大程度上为后续点云分割奠定基础。

Due to the insufficient research on feature extraction of 3D point clouds of flowers at the current stage and the disorder of 3D point cloud data, this paper aims to propose a flower point cloud feature extraction method based on the cylindrical coordinate system. Taking the point cloud data of a single lily flower as the research object, the method uses parameters such as radius, angle and height of the cylindrical coordinate system to establish the topological relationship between points in the point cloud, so as to achieve better point cloud feature extraction. Experimental analysis shows that this method can effectively extract the features of 6 petals from the lily flower point cloud, which largely lays a foundation for subsequent point cloud segmentation.
