Landslide emergency treatment engineering exploration design method based on remote sensing assistance of small unmanned aerial vehicle

Abstract

The invention relates to a landslide emergency treatment engineering exploration design method based on remote sensing assistance of a small unmanned aerial vehicle. The method is characterized by comprising the following steps: rapidly acquiring a high-definition picture of a landslide engineering region in field by using a small unmanned aerial vehicle remote sensing system; generating an orthophoto remote sensing result of the landslide engineering region through digital photogrammetry software processing; making a large-scale line global map by using the orthophoto remote sensing result; carrying out indoor visual auxiliary engineering geological investigation based on an orthophoto and a three-dimensional model; programming a visual conventional engineering geological map according to an on-site engineering geological investigation result; carrying out an auxiliary treatment engineering design based on the visual engineering geological map; programming a visual and conventional landslide emergency treatment engineering design plane map.

Description

technical field [0001] The invention relates to an improved engineering survey and design method, in particular to a landslide emergency control engineering survey and design method based on the remote sensing assistance of a small unmanned aerial vehicle. Background technique [0002] The investigation and design of emergency control engineering is an important part of landslide disaster prevention and control engineering. It is generally an important implementation basis for carrying out emergency control projects in order to avoid the continuous development of disasters and eliminate disaster hazards as soon as possible after landslide disasters occur suddenly or in part. Therefore, on the basis of complying with the relevant norms of landslide prevention and control engineering survey and design, emergency control engineering survey and design should pay special attention to its timeliness, that is, to highlight the word "fast". At the same time, the investigation and de...

Problems solved by technology

[0004] 2. The efficiency of traditional large-scale topographic map on-site measurement is low, and the non-prism total station or GPS-RTK measurement technology is often restricted by the landslide environment and cannot be implemented. In addition, these topographic maps are generated based on discrete "point" measurement interpolation The overall mapping accuracy is not high

At the same time, a single line-drawn topographic map cannot intuitively reflect the comprehensive characteristics of landslides (including topography, vegetation, structures, etc.), which seriously affects the efficiency of engineering exploration, such as the one-time accurate layout of exploration profiles and exploration points cannot be satisfied; at the same time It also affects the accuracy of engineering survey and design results, such as inaccurate coordinates of geological surveying and mapping boundaries, geological feature points, and design plan layout

[0005] 3. The traditional survey and design of landslide emergency control is based on the line-drawn topographic map, and the follow-up work is carried out and displayed in a map. The intuitive visualization effect is poor, and it also affects work efficiency and accuracy.

[0006] Therefore, the traditional landslide emergency control engineering survey and design method is difficult to achieve the "fast" and "accurate" implementation goals
