Description
Summary:The underwater detection imaging technology mainly includes sonar imaging and underwater optical imaging. In order to overcome the disadvantages of low resolution of sonar imaging and short detection range of traditional optical imaging, optical gating technology is applied to underwater fishing net detection. This technology has higher resolution compared to sonar imaging, and its detection range has also been shown to be three times larger than that of conventional optical imaging. However, underwater range gating imaging can suffer from large random noise and low signal-to-noise ratio. In order to solve this problem, this paper proposes a convolutional sparse coding denoising neural network based on deep learning to improve image quality. This network consists of a local residual channel and a global convolutional sparse coding channel. Compared with DnCNN, ECNDNet and other methods, the average Peak signal-to-noise ratio of the proposed method is improved by 1.57~2.11dB, which can effectively remove random noise and reconstruct clear underwater fishing net range-gated images.
