Semantic segmentation plays a crucial role in autonomous driving systems, serving as a key technology for understanding and interpreting the road environment. Most existing semantic segmentation networks strive for high accuracy, but achieving true real-time performance while maintaining high accuracy remains a challenge. However, autonomous driving systems require extremely high reaction speed and real-time processing capabilities, and any processing delay may lead to safety risks. To solve this problem, this paper proposes a lightweight dual-branch multi-scale network (LDMSNet) to achieve real-time semantic segmentation. First, the effective dilated bottleneck (EDB) is proposed to efficiently extract semantic information and spatial information using complementary dual-branch structure and depth-wise dilated convolution. Second, the multi-scale pyramid pooling module (MSPPM) is proposed, which uses a hierarchical residual structure and combines with dilated convolution to extract detailed information from low-resolution branches. Third, the polarized self-attention mechanism (PSA) is introduced to further enhance the interaction and correlation between features and improve the ability to perceive global information. The experimental results show that LDMSNet achieves 74.46% MIoU at 113FPS on the Cityscapes dataset, 71.51% MloU at 153FPS on the CamVid dataset and 77.41% MIoU at 170FPS on the StreetView dataset, effectively balancing speed and accuracy compared to state-of-the-art models.
