摘　　要：基于全景摄影测量的原理,以全景共线条件方程为基础,结合广州市数字城管深化建设之部件普查任务的实际需求,提出并实现了车载全景影像双片测量、单片测量的具体方法;完成了基于二维部件采集成果与三维全景影像自动挂接的所见即所得的部件展示与管理。将全景影像双片量测、单片测量得到的部件采集结果与通过CORS_RTK外业测量模式得到的普查结果进行对比分析,全景测量部件的精度可优于0.5m。实验表明,车载全景摄影测量技术可用于城市部件普查,成为数字城管部件信息采集及更新的一种高效而准确的技术手段。Based on the principle of panoramic photography measurement and collinearity equation, this paper put forward and implemented the methods to measure using single vehicle panoramic image or a pair, and completed the automatic registration between 2D urban components and 3D panoramic ima- ges. By comparing and analyzing the results of panoramic measurement and the results of CORS _ RTK survey, it can be found that the accuracy of panoramic measurement is better than 0. 5 m. It is indicated that vehi- cle panoramic photogrammetry technology can be used in the survey of urban components, and it will be an effec- tive and accurate method for the information collection and updating of digital urban management components.
