Research on fan blade segmentation algorithm based on improved DeepLabv3+ network

Abstract： In order to improve the segmentation quality of fan blade image, this paper proposes a fan blade segmentation algorithm based on improved DeepLabv3+ network. Due to the problems of background assistance and large difference in the proportion of blades collected by UAV, the algorithm proposed in this paper improves the ASPP module and decoder module based on the DeepLabv3+ network. DSAPP concatenates multiple hole convolutions, and transfers the output of each hole convolution layer to the subsequent hole convolution layer by using dense connection. Through a series of feature connections, DSAPP encodes intermediate features of different scales, and obtains a larger range of receptive fields. In the decoder stage, multi-layer feature fusion is added to recover the detail information and all levels of features lost in the down sampling process. Through the experiment of fan blade data set, the MIoU value reaches 0.991 3, PA value reaches 0.996 8. The experimental results show that the segmentation effect of the algorithm designed in this paper is better than that of DeepLabv3+network, and has better detail information.
