Embodiment 1

[0053] Please refer to figure 1 , figure 1 It is a flowchart of an embodiment of the temperature deformation analysis method based on radar interferometry provided by the present invention. The temperature deformation analysis method based on radar interferometry comprises steps:

[0054] S100. Acquire a radar image sequence of a target facility, and extract a target image pair from the radar image sequence.

[0055] Radar images are micro-collected images by radar. When analyzing the deformation of the target facility, the radar image sequence of the target facility is first obtained. Specifically, each image in the radar image sequence can be obtained by analyzing the target facility The radar image in the area is cropped and obtained, such as figure 2 shown.

[0056] In order to eliminate the difference of radar images caused by other factors affecting the analysis accuracy of the deformation of the target facility, in this embodiment, a target image pair is selected i...

Abstract

The invention discloses a temperature deformation analysis method based on radar interferometry. The temperature deformation analysis method based on radar interferometry includes: acquiring a radar image sequence of a target facility, and extracting a target image pair from the radar image sequence; The target image pair is used to obtain a target interferogram; and the temperature deformation of the target facility is determined according to the target interferogram. The temperature deformation analysis method based on radar interferometry obtains the temperature deformation of the target facility by using the interferogram generated by the target image pair in the radar image sequence of the target facility, and analyzes the temperature deformation in the facility deformation separately, which can improve the facility deformation analysis. accuracy.

Description

technical field [0001] The invention relates to the technical field of facility monitoring, in particular to a temperature deformation analysis method based on radar interferometry. Background technique [0002] At present, there are a huge number of various facilities such as bridges and buildings, which play an important role in economic and social development. After these facilities are built and used, they will deform with the continuous increase of operating time and environmental loads, which will affect the facilities in severe cases. The normal use of the facilities will not only cause economic losses, but also threaten the safety of the people. Therefore, the deformation analysis of facilities is very necessary. However, the current facility deformation analysis is often to analyze the overall deformation of the facility, and the deformation caused by the temperature change has a strong periodic trend, and sometimes the magnitude of the temperature deformation will ...
