摘　　要：提出利用全站仪免棱镜对边测量功能来间接精确、快速获取楼高数据的方法。根据测量平差原理推导出该法的精度以确定其适用的精度范围和应用领域，应用该法及传统悬高测量、影像测量的方法，对广西南宁市10座不同高度的建筑物进行实测，将所测数据与经典的坐标测量数据进行比较，全站仪免棱镜对边测量其精度范围在1／175～1／556，大大优于悬高测量（1／14～1／232）与影像测量（1／51～1／263）结果的精度。对边测量具有自由设站的优点，使其能在任意位置量测高层建筑的高度，极大的提高了作业的效率。By the method of non-prism MLM function, precise and fast acquisition can be obtained from the building height data. Based on the principle of the survey adjustment, the precision of this method is deduced , the scope of precision range and the application field are also determined. Non-prism MLM, REM and the image survey method are applied to 10 buildings in Nanning. Compared with the classical coordinate survey, the precision of the non-prism MLM ranges from 1/175 to 1/556, better than REM （1/14 to 1/232） and image survey （1/51 to 1/263）. The advantage of free location and non-prism MLM method improves the efficiency greatly in high building height survey.
