The invention provides a road extraction method and device applied to a remote sensing digital image, applied to the technical field of remote sensing image processing, and the method comprises the steps: obtaining a current remote sensing digital image; processing the current remote sensing digital image by using a pre-trained road extraction model to generate a road extraction image; and processing the road extraction image by using a pre-trained road optimization model to generate a road optimization image. By means of the road extraction method applied to the remote sensing digital image, semantic segmentation can be achieved, the road extraction image is repaired without depending on the remote sensing image, road detail information presented in the high-resolution image can be fully utilized, and the road extraction efficiency is improved. And interference caused by shielding and shadow due to high resolution can be removed. 本公开提供了一种应用于遥感数字图像的道路提取方法和装置，应用于遥感图像处理技术领域，所述方法包括：获取当前遥感数字图像；利用预先训练的道路提取模型对所述当前遥
