Intelligent identification of landslide disaster based on deep learning of UAV images
An open-pit mine landslide identification method was proposed based on object-oriented annotation datasets and the Res-U-Net model to realize accurate identification and early warning of open-pit mile landslide disasters.Firstly,the mine landslide image data in the study area were obtained by UAV aerial survey.Secondly,the multi-scale-spectral segmentation method and threshold separation principle were applied to divide and classify the open-pit mine landslide data,and the landslide dataset was developed based on the object-oriented method.Then,the U-Net network was used as the infrastructure to propose a landslide identification semantic segmentation model based on Res-U-Net by integrating the residual module into each convolutional layer.Finally,the datasets constructed by different methods were used to identify landslides,and the Res-U-Net model was compared with the widely used semantic segmentation models,Fully Convolutional Networks(FCN),and U-net.The results indicated that the landslide data set based on object-oriented annotation had better landslide identification performance when compared to the traditional manual annotation dataset,resulting in improvements in identification accuracy,recall rate,F,score,and kappa coefficient of more than 12%.The landslide identification accuracy of the Res-U-Net model was more than 0.8,realizing the accurate landslide open-pit mine disaster identification.
