Research on Oblique Photography Modeling and Building Deformation Monitoring Methods
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 u-sing the method of comparative analysis of the accurate point position data of special points collected by the two periods of high-accu-racy oblique photography model and the NTS-A11R10 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 horizon-tal and vertical displacement at the special points of the target building.This method can preliminarilyidentify the deformation and dis-placement of the building,analyze the safety degree of the building according to the comparison results,and ensure the safe operation of the building.
