| 摘 要： | 提出利用尺度不变特征来描述三维模型的局部形状信息,设计出一种灰度体素模型上的基于三维SIFT算法的局部形状特征提取方法;得到三维模型的尺度不变形状特征后,采用BoF方法构建模型的形状特征向量,配合相应的距离函数实现三维模型"部分-整体"的匹配和检索。实验表明该方法具有比较好的检索性能。

| Abstract: | A scale-invariant shape feature was extracted on gray voxel models by a SIFT-like algorithm to describe the local shape information of 3D models of mechanical parts.Shape feature vectors were constructed by a BoF method and compared by a distance function that supported the part-in-whole matching.Experiments demonstrate that the proposed method achieves a satisfactory retrieval performance. |
