Abstract

At present, most of the semantic segmentation algorithms for road scenes are aimed at visible images, but the visible images collected in dark and other special conditions will seriously affect the accuracy of semantic segmentation, so to enhance the ability to understand the night road scene, this paper obtains the infrared image of the night road scene, based on the improved DeepLabV3+ network structure, so that the network takes into account both segmentation accuracy and real-time performance. First of all, MobileNetV2 is used as the backbone network to reduce the amount of computation and the number of parameters in the network. Secondly, the channel and spatial attention modules are used in the encoding and decoding stages to obtain rich context information, filter background information, and reduce the loss of detailed information. Finally, the tightly connected atrous spatial pyramid pooling (ASPP) module is introduced, which not only expands the receptive domain but also extracts more abundant multi-scale features. The experimental data show that the average intersection-merge ratio of this algorithm is obviously better than that of the DeepLabV3+ algorithm on infrared data sets, and the average intersection-merge ratio can reach 81.45, showing better accuracy and real-time performance.
