摘要
为降低三维模型检索的时间复杂度,提出一种基于同心球面分割的三维模型检索方法。通过预处理、设置同心球半径、模型分割,提取特征向量,对提取的特征向量做相似性匹配,计算特征比较值,得到检索结果。对比实验表明,该方法可以在较短的响应时间获得较优的检索性能。
In order to reduce the time-complexity of 3D model retrieval, puts forward an approach based on concentric sphere segmentation for 3D model retrieval, achieves the result of retrieval by means of the operation of processing, setting radius of concentric sphere, segmentation model, feature extraction and matching. Comparative experiments show that the method can be obtained in a shorter response time on better retrieval performance.
