Problems solved by technology

[0004] Due to the complex road conditions in mountainous areas, when natural disasters such as landslides and mudslides occur in mountainous areas, the failure of rescuers to rush to the accident site in time is one of the main reasons for casualties in the area where the accident occurred; because the natural disaster itself is the structure of the mountain Due to the complex road conditions, it is impossible to manually determine and judge the specific location of rescuers at the scene of the accident; rescuers need to spend a lot of time searching and rescuing to determine the location of rescuers, wasting a lot of rescue time and energy, and getting twice the result with half the effort; at the same time, due to the Internal transportation is inconvenient, and rescuers cannot determine the specific affected area of ​​the landslide and mudslide area, and cannot plan a reasonable search and rescue route and rescue plan based on the affected area

Embodiment 1

[0024] Embodiment 1: a kind of method based on unmanned aerial vehicle monitoring mountain landslide, mud-rock flow, comprises the following several steps:

[0025] a) When a landslide or mudslide accident occurs in a mountainous area, use known information and computer technology to draw the accident area and flight route for the first flight of the UAV;

[0026] b) According to the initial flight route formulated by the computer, the UAV performs its first flight. During the flight, the UAV is equipped with imaging equipment. When it enters the estimated accident area, the imaging equipment is turned on, and the whole process of the UAV is taken with the positioning equipment. On-site mountain conditions in the flight area;

[0027] c) According to the video recorded during the first flight and the coordinates recorded by the positioning equipment, the images and data obtained by the aerial photography of the drone are imported into the 3D simulation computer for manual comp...

Embodiment 2

[0033] Example 2: During the initial flight of the UAV in step b), the UAV flies along the sideline of the planned accident area to confirm the specific scope of the accident area; if the actual area of ​​the accident area is found in step c) If it is larger than the planned accident area, step a) needs to be re-executed;

Embodiment 3

[0034] Example 3: During the actual manual comparison in step f), when people are found to be calling for help or victims of a disaster during manual observation and comparison, cooperate with the positioning equipment carried by the drone to determine the location information of the personnel, and re-execute d )-f) steps, in the process of repeated flight, it is necessary to send rescue to the designated location for rescue.

Abstract

The invention discloses a method for monitoring landslides and debris flows in mountainous areas based on an unmanned aerial vehicle. The directional cruise of the unmanned aerial vehicle and the imaging equipment and positioning equipment carried by the unmanned aerial vehicle are used for shooting, and the collected data are carried out by computer software. Analyze and formulate accurate rescue methods and route methods for landslides and debris flows in mountainous areas; the present invention can accurately determine the disaster-affected area in the area where landslides or debris flows occur by applying UAV remote sensing technology to the field of emergency rescue in mountainous areas, Through computer modeling and planning, UAVs can be used to search seamlessly, quickly and comprehensively monitor the disaster situation in the disaster-stricken area, and send the information to the rescue command office in time, so that rescuers can plan and accurately plan in time The rescue route greatly improves the rescue efficiency; it is suitable for the detection of disaster-stricken mountainous areas in various complex situations.

Description

technical field [0001] The invention relates to the field of emergency rescue in mountainous areas, in particular to a method for monitoring landslides and debris flows in mountainous areas based on an unmanned aerial vehicle. Background technique [0002] Landslides and mudslides refer to special natural disasters caused by torrential rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain, which carry a large amount of sediment and stones. Landslides and debris flows have the characteristics of suddenness, fast flow, large flow, large material capacity and strong destructive power. Traffic facilities such as roads and railways and even villages and towns are often washed away, causing huge losses. [0003] UAV remote sensing systems mostly use small digital cameras (or scanners) as airborne remote sensing equipment. Compared with traditional aerial photographs, there are problems such as small image size and large...
