摘要
以体素构造三维模型原理为基础,阐述了体素的几何信息和体素间的拓扑关系及基准问题,建立了三维模型特征提取函数,并对其旋转、平移和尺寸变化进行了经典不变矩处理,提出了一种基于体素构造和遗传算法的三维模型检索方法。该方法通过对遗传信息编码,以及迭代中的遗传信息交叉与变异,减小了检索区域的收敛速度,提高了检索准确率和检索速度。
The voxels structure principle of 3D model as the foundation, expounds the voxel geometryinformation and body elements of topological relations and benchmark problems, establish the 3Dmodel feature extraction function and of its rotation, translation and size changes of classic momentinvariant processing, put forward a based on voxel structure and genetic algorithm of 3D modelretrieval method. This method reduces the convergence speed of the search area and improves theretrieval accuracy and retrieval speed by the genetic information encoding, the genetic information inthe iteration and the variation of the genetic information.
