The invention discloses a CML-sinGAN-based side-scan sonar underwater target image sample amplification method, and belongs to the technical field of side-scan sonar image target recognition and amplification and deep learning. The method specifically comprises the steps that firstly, an eight-layer-scale pyramid network structure is designed according to the characteristics of a side-scan sonar image, and the diversity of a generated image is improved while image textures are fully learned; secondly, fusion is carried out in a generator, and information dispersion is reduced while target learning is enhanced; then, a loss function based on L1loss is introduced into the discriminator, the discrimination capability of the discriminator on the authenticity of the target is enhanced, and unreal false pictures are removed; and finally, based on the conversion model, carrying out high-quality amplification on the existing small sample side-scan sonar image, and carrying out YOLOv7 identification detection by using the amplified image. The method provides a new way for side-scan sonar small target sample amplification and a high-performance underwater target detection model.

This invention relates to an integrally woven pile sandwich mesh fabric and its weaving method. The integrally woven pile sandwich mesh fabric is woven in one piece using a warp knitting machine equipped with no fewer than seven ground comb bars. It includes a face layer, a middle layer, and a bottom layer. The face layer is woven using the chain blocks of the jacquard or ground comb on the machine in any weave pattern. The middle layer is woven using yarns connected to the face and bottom layers in a weave pattern. The bottom layer is woven using the chain blocks of the jacquard or ground comb on the machine in any weave pattern. This invention, through reasonable process design of each comb bar, fully utilizes the advantages of jacquard and ground combs, combines the variations in yarn threading of the comb bars, and employs precise design and the use of synthetic fibers to produce an integrally woven sandwich three-dimensional pile mesh fabric with characteristics of being skin-friendly and soft, lightweight, high-performance, and structurally stable.
