[0001] The present invention relates to the technical field of building settlement, and in particular to a building settlement observation device and a use method thereof based on image recognition. Background Art

[0002] Building settlement refers to the phenomenon that the foundation moves vertically downward during the construction or use period of the building due to the weight of the building or other external forces in extremely bad weather. During the construction or use period of existing buildings, settlement observation devices are usually installed to observe whether the building moves up or down and the range of the up or down movement, so as to improve the safety of the construction or use of the building. The existing building settlement observation devices still have the following disadvantages when used:

[0003] First, the existing building settlement observation device is usually fixed to the building, and settles with the building. The settlement distance is judged by observing the displacement of the device. This observation device has great limitations, low observation accuracy, and large errors in the observation results.

[0004] Second, the building settlement observation device cannot determine whether the observed settlement data is caused by ground settlement or building settlement, and the observed results are unstable.
