摘　　要：三维模型数据应用广泛,但其结构复杂,每个数据应用平台都需要建立独立的数据库,甚至数据格式都不能兼容。为此,测绘单位需要根据模型数据情况对每个三维数据库分别进行更新维护。目前尚无多个三维平台之间数据维护与管理的解决方案。在三维模型批量单体化、BIM模型轻量化处理的基础上,提出了多个三维平台数据间高效转换算法,形成了一套综合性三维模型数据组织管理方法,实现三维模型数据的跨平台快速更新,为跨平台数据的协同更新和城市三维模型数据的系统性管理提供了一套全流程的解决方案。该方法在常州市新北区三维模型数据的组织管理工作中运用,大幅度提高了生产效率,效果良好。3 D model data is widely used, but its structure is complex. Each data application platform needs to establish an independent database, and even the data format is not compatible. Therefore, the surveying and mapping company needs to update and manage each 3 D database according to the model data structure. Currently, there is no solution for data organization and management between multiple 3 D platforms. Based on the batch of 3 D single-model and the simplified processing of BIM model, an efficient conversion algorithm between multiple 3 D platform data is proposed, forming a set of comprehensive 3 D model data organization and management method to realize the cross platform rapid update of 3 D model data, It provides a whole process solution for the collaborative updating of cross platform data and the systematic management of urban 3 D model data. It has been applied in the organization and management of 3 D model data in Xinbei district of Changzhou city, which has greatly improved the production efficiency and achieved good results.
