To solve the problem of low accuracy and low speed of linear flexible body segmentation,an improved DeepLabV3+network was proposed.The MobileNetV2,a lightweight and easy-to-converge feature extraction network,was utilized as the backbone network.The CA(channel attention)module was employed to concentrate on key information in the input features.A multi-scale atrous pyramid pooling structure was introduced to enhance the network's receptive field and training efficiency.In the decoding stage,an improved cascaded feature fusion module was proposed to fuse three shallow-level features,thereby improving the representation capability of semantic information.Experimental results show that compared with the non-improved network,the improved network improves MIOU and IOU by 2.82%and 3.46%,respectively,and reduces the prediction time by 5.2 ms,which can realize the accurate segmentation of deformable linear objects under complex background.
