Research On The Automatic Extraction Method For Highway Slide Scale Based On Image Processing

Landslide is a common and harmful geological disasters,not only after the occurrence of landslide will endanger people's life and property security,often also can cause buried houses,traffic block,and even cause secondary disasters such as quake lakes.Of highway landslide after the rapid repair is particularly important to restore the traffic as soon as possible,especially when landslides as secondary disasters to other natural disasters,the fast repair the landslide blocking traffic "lifeline" will be related to the rescue and relief of each link,so the first time for landslide scale information can provide effective data for the policymakers repair scheme.Based on their actual participation in emergency rescue mission experience and armed police traffic forces existing problems and difficulties in the process of emergency rescue,explore how to apply knowledge in actual rescue activities,promote forces under the new situation of emergency rescue ability.In this paper,based on the conventional calculation method for the landslide scale,addresses the automatic extraction method of landslide scale research,discussed the MATLAB software to carry on the basic principle of image segmentation method,on the basis of the original image segmentation method for different study the experiment of landslide did back together after improvement,proposed by region growing,k-means clustering method are edge region growing and image segmentation method mainly three kinds of combination,to achieve complete landslide region more accurately extract the purposes;The landslide area is calculated by the projection scale and the Imfill function,and the calculation results are compared.Based on Photoscan software as a massive landslide and unmanned aerial vehicle(uav)image,try to take advantage of volume calculation module and the known point in the software of GPS information of landslide volume calculation,achieve the goal of landslide scale automatic extraction;According to the combination of three kinds of image segmentation method is proposed in MATLAB GUI software platform in the design of the corresponding calculation program,and according to different instances of landslide landslide area through the automatic program of extraction and accuracy of the results.
