摘　　要：针对传统人工违法建设巡查存在的不足,以广州市天河区为例,提出一种以倾斜摄影测量技术为基础,融合并行计算、建筑单体化建模、变化检测、二三维联动矢量提取技术为一体的违法建设巡查模式。实践证明本方法能快速获取复杂场景下的违法建设图斑及属性信息,制作指引图册、统计表格和专题数据库,为违法建设动态监测提供了有效手段。In view of the shortcomings of traditional artificial illegal construction inspection, taking Tianhe District of Guangzhou for example, we put forward an illegal construction inspection mode based on oblique photogrammetry technology, which integrated parallel computing, building monomer modeling, change detection and two or three-dimensional linkage vector extraction technology. The practices prove that this method can quickly obtain the information of illegal construction map spots and attributes in complex scenes, make guide atlas, statistical tables and special databases, and provide an effective means for dynamic monitoring of illegal construction.
