主 题:side scan sonar images autonomous underwater vehicle multisize parallel convolution module attention mechanism
摘 要:Side scan sonar(SSS)is an important means to detect and locate seafloor *** underwater vehicles(AUVs)carrying SSS stay near the seafloor to obtain high-resolution images and provide the outline of the target for *** target feature information of an SSS image is similar to the background information,and a small target has less pixel information;therefore,accu-rately identifying and locating small targets in SSS images is *** collect the SSS images of iron metal balls(with a diameter of 1m)and rocks to solve the problem of target ***,the dataset contains two types of targets,namely,‘ball’and‘rock’.With the aim to enable AUVs to accurately and automatically identify small underwater targets in SSS images,this study designs a multisize parallel convolution module embedded in state-of-the-art *** attention mechanism transformer and a convolutional block attention module are also introduced to compare their contributions to small target detection *** performance of the proposed method is further evaluated by taking the lightweight networks Mobilenet3 and Shufflenet2 as the backbone network of *** study focuses on the performance of convolutional neural networks for the detection of small targets in SSS images,while another comparison experiment is carried out using traditional HOG+SVM to highlight the neural network’s *** study aims to improve the detection accuracy while ensuring the model efficiency to meet the real-time working requirements of AUV target detection.
