Abstract

The invention discloses a method for post-disaster damage assessment of buildings by using unmanned aerial vehicles, and relates to the field of disaster assessment. Multiple unmanned aerial vehicles(UAVs) are used to shoot the images of the disaster area, and then TIFF format remote sensing images of the disaster area are quickly constructed on a GPU server by using the photographed high-definition images transmitted from the UAVs. the neural network image segmentation model is used to extract the intact houses from the remote sensing images and compare them with the remote sensing images before the disaster, the block is taken as the unit to record the damaged data and corresponding GPS coordinates, and the geographic coordinates polar spherical projection is used to draw the distribution map of the damaged houses on the map of the disaster area. The invention can quickly evaluate the disaster situation, and the detection result has high credibility.

Description

technical field [0001] The invention relates to the field of disaster assessment, in particular to a method for evaluating damaged buildings after a disaster by using an unmanned aerial vehicle. Background technique [0002] Disaster assessment is the judgment and estimation of disaster situation. The mainstream means of disaster assessment in modern society is through satellite remote sensing images. Moreover, there is a shortcoming of too long evaluation period for disaster assessment through satellite remote sensing images. After the disaster occurs, people hope to provide a reference for the next dispatch of personnel and materials for earthquake relief by quickly assessing the disaster situation. [0003] Therefore, those skilled in the art are devoting themselves to developing a new system that can quickly assess the disaster situation after the disaster occurs. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, the technica...
