| 摘 要： | 研究了一种基于多视图SIFT特征的三维模型检索算法。首先对三维模型进行多视图投影，得到其余方位的三维投影深度图，并在各投影深度图上提取SIFT特征。分别利用按模型特征数比例分次建立码本及建立模型库整体码本这两种方式建立了模型库的码本，继而将模型的SIFT特征聚类量化，并用一个多维向量将其表示出来。通过计算三维模型特征向...

| Abstract: | A 3D model retrieval algorithm based on multi-view scale invariant feature transform(SIFT) feature is researched.By carrying on the multi-view projection of a 3D model,the omnidirectional 2D projection depth maps are obtained,from which SIFT features are extracted.Individual-k-means and Whole-k-means are used to establish the codebook for shape benchmark respectively.Using the feature quantization codebook,all the features are clustered and generated the histogram as the 3D model feature vector.The similari... |
