- Abstract:
-
Based on Google and UAV remote sensing images,the D-LinkNet neural network was used to extract the information of the damaged buildings in Longtoushan Town caused by the 2014,Ludian,Yunnan MS6.5 earthquake.Then the intensity in Longtongshan Town was calculated according to the statistical value of the mean earthquake-damage index.A detection of the advances in the reconstruction of the buildings in Longtoushan Town was carried out based on D-LinkNet model.Then the extracted results of the damaged buildings were intersected with the detection results of the reconstructed buildings,and the evaluation coefficients of building reconstruction were set up and the reconstruction degree of the damaged buildings was determined.The results showed that Longtoushan Town was located both in Intensity Ⅷ area and Intensity Ⅸarea.In 2015,the buildings in Longtoushan Town wereevaluated as “basically restored”,while in 2018,they were evaluated as“completely restored”.The extracted results and evaluated results in this paper were compared with the information released by the China Earthquake Administration and other relevant departments.The consistency of the results given in this paper with the results released by authorities proved that the proposed method in this paper is accurate.
