Remote sensing image instance classification method and system, terminal and storage medium

The invention provides a remote sensing image instance classification method and system, a terminal and a storage medium. The method comprises the steps: acquiring a high-resolution panchromatic remote sensing image and a multispectral remote sensing image of a target geographic area; carrying out instance labeling on the acquired high-resolution panchromatic remote sensing image and the acquired multispectral remote sensing image to obtain a labeled high-resolution panchromatic remote sensing image and a labeled multispectral remote sensing image; respectively carrying out image feature extraction on the labeled high-resolution panchromatic remote sensing image and multispectral remote sensing image to obtain a panchromatic image feature map and a multispectral image feature map; carrying out feature fusion on the obtained panchromatic image feature map and the multispectral image feature map to obtain a fused feature map; and inputting the fused feature map into a classification convolutional neural network
