Neural Implicit Surface Reconstruction using Imaging Sonar [PDF]
IEEE International Conference on Robotics and Automation, 2022 We present a technique for dense 3D reconstruction of objects using an imaging sonar, also known as forward-looking sonar (FLS). Compared to previous methods that model the scene geometry as point clouds or volumetric grids, we represent the geometry as ...

A Side-Scan Sonar Image Synthesis Method Based on a Diffusion Model
Journal of Marine Science and Engineering, 2023 The limited number and under-representation of side-scan sonar samples hinders the training of high-performance underwater object detection models. To address this issue, in this paper, we propose a diffusion model-based method to augment side-scan sonar

A Texture Feature Removal Network for Sonar Image Classification and Detection
Remote Sensing, 2023 Deep neural network (DNN) was applied in sonar image target recognition tasks, but it is very difficult to obtain enough sonar images that contain a target; as a result, the direct use of a small amount of data to train a DNN will cause overfitting and ...

SCENARIOS FOR BENCHMARKING RANGE-DEPENDENT ACTIVE SONAR PERFORMANCE MODELS
VALIDATION OF SONAR PERFORMANCE ASSESSMENT TOOLS 2010, 2023 A set of eight sonar problems, pertaining to man-made active sonar, with source frequencies ranging from 250 Hz to 3.5 kHz, is defined. The scenarios are designed to emphasize range dependent propagation aspects in coastal waters, with the aim of testing
