中文摘要： 三维建筑综合是三维地图综合研究的重要组成部分，对于建立三维城市的多尺度细节层次模型具有重要作用。基于质量控制思想研究三维建筑几何模型的自动综合，对于提高三维建筑综合算法的设计效率和稳定性，改善综合所生成的三维建筑多尺度模型质量具有重要的理论意义和实用价值。研究具体内容包括：1）在分析三维建筑综合约束的基础上，研究综合约束条件的生成方法，实现部分综合相关语义信息的自动提取，并基于双重约束实现三维建筑综合区域的层次划分；2）建立综合算子几何约束与单尺度控制参数之间量化对应关系，实现基于多重约束的三维建筑几何模型综合算法，并引入过程控制和综合中间结果的反馈机制，以提升算法稳定性和综合结果可靠性；3）从拓扑一致性、位置精度和几何形态等方面出发研究三维建筑几何模型综合结果的质量评价方法，通过细化评价指标，基于应用目标量化评价综合总体质量，建立较为完善的综合质量评价体系。

英文摘要： 3D building generalization is a main part of 3D map generalization,and plays an important role in establishment of 3D city model. Study on automatic generalization of 3D building geometry model based on quality control method is of great theoretical significance and practical value in improving design efficiency and stability of generalization algorithm, and the quality of generalized model. The main contents include: 1) based on the analysis of 3D building, constraints in 3D building generalization is analyzed and the generation method is studied in this part. Part of semantic information used in generalization is automatically extracted and 3D building generalization areas are generated under dual constraints. 2) Quantitative relationship between geometric constraints of different generalization operator and single scale control parameters are establish, and then algorithm under multiple constraints is realized in generalization of 3D building models. Process control and feedback mechanism are introduced in the algorithm to enhance stability and achieve better generalization result. 3) Quality evaluation method of generalized 3D building geometry mode is studied based on topological consistency, position accuracy and geometry forms, and comprehensive quality comprehensive evaluation system is established by us
