Abstract：This paper discusses the application of Building Information Modelling(BIM)technology and UAV oblique photography technology in the deformation monitoring of steel structure operation and maintenance stage,and the main steps include BIM modelling and selection of reference base points,UAV oblique photography parameter setting,field flight,internal data processing,comprehensive application of point cloud model and BIM model,etc.The results show that the combination of BIM modelling and UAV oblique photography can effectively monitor the deformation of steel structures and provide accurate and efficient monitoring data.Comparing the point cloud model obtained by the drone with the BIM model,the abnormal deformation and potential safety hazards of the building can be found in time.This technology is helpful to summarize the temperature strain law of steel structure,realize intelligent deformation diagnosis and early warning,and provide a new method and a new choice for steel structure deformation and safety monitoring.
