摘　　要：针对建筑物在建设期可能出现的沉降、变形等问题,本文通过对某项目进行倾斜摄影数据采集,采用Context Capture软件进行模型生产,利用两期高精度的倾斜摄影模型点位与NTS-A11R 10 S全自动伺服马达全站仪采集的特殊点精准点位数据对比分析的方法,对比两期模型点位与全站仪测量点位对特殊点进行水平、垂直点位变化,实现对建筑物自身变形判断。结果表明:目标建筑物特殊点位未产生明显水平与垂直位移,该方法能够初步判断建筑物的形变位移情况,根据对比结果分析建筑物的安全程度,保证建筑物的安全运行。In view of the settlement,deformation and other problems that may occur during the construction period of the building,this paper collects oblique photographic data for a project in the study area and uses ContextCapture software for model production.By using the method of comparative analysis of the accurate point position data of special points collected by the two periods of high-accuracy oblique photography model and the NTS-A11R 10 S automatic servomotor total station,the horizontal and vertical point position changes of special points were analyzed by comparing the two periods of model point positions and the total station measurement point positions,so as to realize the determination of the deformation of the building itself.The results show that there is no obvious horizontal and vertical displacement at the special points of the target building.This method can preliminarilyidentify the deformation and displacement of the building,analyze the safety degree of the building according to the comparison results,and ensure the safe operation of the building.
