融合Fuzzy拓扑关系与CRSC的三维模型检索方法
Method of three dimensional model retrieval based on Fuzzy topology and CRSC
摘要
Abstract
Three-dimensional model retrieval method based on Fuzzy topological relations and Corner Representative Shape Context(CRSC)is proposed in order to solve such problems as the expression of fuzziness and draw arbitrary when freehand sketch retrieves three dimensional models. For a topological characteristics description of the model, it extracts Fuzzy topological relations of binary primitive and optimizes the redundancy problem of binary primitive charac-teristic vectors. Then, the searchable recognition rate and robustness is increased by using CRSC. The neighbor node traversal algorithm is proposed according to multiple points of view rendering uniqueness. Simulation results show that this method has a high recognition rate, and the efficiency of the user draws is improved.关键词
