Abstract

Aiming at the problems of low accuracy and missing of some details in road extraction by existing road extraction methods, this paper proposes a road extraction method integrating improved PSPNet. This method mainly improves the original PSPNet model by embedding SGE attention mechanism in the convolutional neural network stage to enhance the extraction accuracy. In pyramid pooling, Hybrid Dilated Convolution is used to replace global mean pooling to enhance the attention to details. In order to verify the effectiveness and feasibility of the proposed method, the improved model in this paper was compared with other common road extraction models. The experimental results show that compared with other methods, the proposed model has higher accuracy and integrity for road segmentation, and has certain practical application value.
