Description
Technical Field

Background
The dam is an important basic project for optimizing water resource allocation by adjusting the space-time distribution of water resources, and plays an important role in various aspects of power generation, shipping, irrigation, industry and the like. However, due to the influence of geological environment, construction quality, water flow flushing and the like, the dam may deform, cause uneven settlement, crack and the like, and if such problems cannot be found and handled in time, the safe operation of the dam is difficult to ensure. The safety monitoring of the dam is an effective means for knowing the running state of the dam and evaluating the health condition of the dam, and proper maintenance plans and maintenance measures can be formulated through monitoring data, so that the structural safety of the dam is ensured.
The surface deformation of the dam is the most intuitive reaction and is also the most important monitoring index. The current common dam surface deformation monitoring technology mainly comprises manual observation and automatic monitoring. The manual observation method mainly comprises a macroscopic geological monitoring method, a simple monitoring method, a station setting observation method, a geodetic precision measurement method, an instrument monitoring method and the like, but is limited by single monitoring content, large influence by meteorological and topographic conditions, low precision, large labor intensity, complex operation, poor stability and difficult continuous monitoring, so that the monitoring effect is poor. The automatic monitoring method is mainly applied to an automatic system based on a measuring robot and a GNSS system based on a global satellite positioning technology, the technical cost of the measuring robot is high, equipment is difficult to protect, and the equipment is greatly influenced by weather factors; GNSS has high requirements on the arrangement points, shielding and interference of high-voltage power, signal towers and the like cannot be caused around, and the difference algorithm is adopted for resolving, so that the data has certain hysteresis.
The machine vision technology is a new technology developed in recent years, and mainly simulates and recognizes the vision ability of a person through a computer, and then obtains various parameter information of a target structure through an image processing algorithm. Therefore, machine vision is widely used in deformation monitoring of infrastructure. However, for a dam with a longer dam body or a curved dam, the following disadvantages are also caused by the application of the visual technology for monitoring: firstly, the dam is large in volume, a single camera machine vision monitoring system is limited by the field of view of image acquisition equipment, and the whole dam is difficult to monitor in a whole coverage way; secondly, the visual monitoring equipment is limited by physical factors such as a lens, and the range of clear observation is limited, and when the visual monitoring equipment exceeds the zoom range of a camera, the accuracy of the monitoring equipment is reduced to some extent; thirdly, because the monitoring device needs to be installed on a fixed position with higher stability requirement and needs to be manually adjusted when displacement occurs, the feasibility of monitoring the dam by installing a plurality of cameras is limited; fourth, the reliability of the monitoring data cannot be checked in real time by the existing equipment.
In view of the foregoing, there is a need in the art to provide a dam monitoring apparatus and system that overcomes the shortcomings of the prior art.
