Problems solved by technology

More importantly, the environment of the slope is changeable. If a single UAV is affected by the environment, it will inevitably lead to large errors in the detection results. Therefore, it is difficult to guarantee the accuracy of the monitoring results when using a single UAV for monitoring.

Abstract

The invention provides a slope monitoring method based on the multiple unmanned aerial vehicles. The slope monitoring method comprises the steps that multiple monitoring points can be arranged on a slope, all the unmanned aerial vehicles can pass through the slope according to a preset flight route and monitor passing monitoring areas in real time, and when the unmanned aerial vehicles monitor that an abnormal monitoring point with displacement exists in the monitoring areas, the unmanned aerial vehicles can broadcast the geographic coordinates of the abnormal monitoring point to other unmanned aerial vehicles. After other unmanned aerial vehicles receive the geographic coordinates of the abnormal monitoring point, the abnormal condition at the geographic position corresponding to the geographic coordinates can be verified, a verification result is broadcasted to all the unmanned aerial vehicles, and after all the unmanned aerial vehicles receive the verification result broadcasted bythe other unmanned aerial vehicles, whether the monitoring point corresponding to the geographic coordinates truly shifts or not can be judged by integrating the verification results fed back by all the unmanned aerial vehicles. Thus, the verification results can be verified from different positions, directions and the like through the multiple unmanned aerial vehicles, the abnormal monitoring point can be accurately recognized, and the accuracy of the monitoring results is ensured.

Description

technical field [0001] The invention relates to the technical field for measuring ground deformation and movement, in particular to a slope monitoring method based on multiple unmanned aerial vehicles. Background technique [0002] In order to grasp the movement of slope rocks and find signs of slope failure, it is necessary to monitor the speed and direction of slope displacement. UAVs can also be used for slopes because they have a wide monitoring range and are not affected by the geographical environment. monitor. For example, the patent "UAV-Based Highway High Slope Inspection Method" (publication number CN109695260A) specifically discloses a method for monitoring highway slopes by using an unmanned aerial vehicle. The patent "A System and Method for Monitoring Slope Deformation" (Notice No. CN110453731B) discloses a technical means of monitoring dam deformation using unmanned aerial vehicles. The patent "A Method for Three-dimensional Visual Modeling of Highway Slopes...
