DYNAMIC CHANGE MONITORING OF QIANLONG GARDEN ROCKERY IN FORBIDDEN CITY BASED ON INSAR AND LIDAR TECHNOLOGY

Guo, M.; Zhou, Y.; Zhou, T.; Pan, D.

The traditional method of deformation monitoring involves a large amount of external field measurement and internal processing to obtain the deformation of the measured object. With the development of InSAR technology, deformation monitoring can now be completed more efficiently. In this paper, InSAR technology and LiDAR technology are used to detect the deformation of the Fuwangge Rockery in Qianlong Garden, InSAR technology can provide higher point accuracy and LiDAR technology can provide higher spatial resolution. After the deformation of the rockery is obtained by LiDAR technology, the InSAR experimental results are verified. It is expected that the error of deformation analysis by the two methods will be within 5mm. Finally, the detection results of the two are consistent with each other and complement each other. At the same time, InSAR technology combined with LiDAR technology also provides a new idea for deformation monitoring.
