[0044] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0045] A hyperspectral remote sensing image classification method based on a dense residual three-dimensional convolutional neural network (DR-3D-CNN) according to the present invention, the schematic diagram of the network structure is as follows figure 1 shown, including the following steps:
[0046] Step 1, using the original sample of the hyperspectral remote sensing image to construct a virtual sample, mixing the original sample and the virtual sample to form a training sample, the training sample is a three-dimensional data cube; the details are as follows:
[0047] Using the original sample data of the hyperspectral remote sensing image through simulated imaging, random factors and random noise are added to the original sample to form a virtual sample. The virtual sample is a pseudo sample transformed from the original ...
