三维模型搜索通用支撑平台的设计与实现*

为满足模型搜索研究领域对数据管理、算法配置和算法验证等工具的集成需求，提出一个模型搜索支撑平台框架。利用面向对象技术，构造一个包含应用程序表现层、应用程序工具层、算法逻辑层、数据抽象层、数据访问层和数据层的多层体系结构；基于“一具体类一表”映射策略实现对象型数据与关系型数据的映射；采用策略模式实现了算法组合和替换的动态配置机制。实际应用表明，该平台可为模型搜索研究提供工具支持。

Design and implementation of supporting platform for 3D model retrieval

Due to the requirement of integrating tools for model retrieval-related data management,algorithm configuration and algorithm validation,this paper proposed a general supporting platform for 3D model retrieval.Through object-oriented design and analysis technology,established a multilayer architecture including applications,tools,algorithm,data abstraction,data accessing and data layer.Based on one inheritance path one table mapping strategy,mapped object-oriented model to relational data model,and constructed mechanism of dynamic configuration for displacement of algorithms by adopting strategy pattern.Results of application instance reveal that the platform provides necessary tools for 3D model retrieval.
