摘　　要：3D SLAM移动测量系统采用了全新的数据采集方式,本文在城市测绘具体项目中,运用该系统进行测试应用,并通过采集的三维点云数据与传统全站仪采集的数据进行精度比对分析,结果表明室内测量中,相对精度为2.5 cm,在室外测量绝对坐标系下,道路竣工为14 cm,小区竣工18 cm,建筑竣工为9 cm,能满足大部分城市测量要求。A new data collecting method is carried for the 3 D SLAM mobile surveying system. In this paper,the system is used in Urban Surveying,the accuracy analysis result is given,based on the data collected in the traditional way with total station and 3 D SLAM surveying system. It is showed that relative accuracy of indoor surveying is 2.5 cm,the road final acceptance is 14 cm,the subsidence final acceptance is 18 cm,the normal building final acceptance is 9 cm. So the system meet the most urban surveying demand.
