SSS Data Preprocessing
Raw Side-Scan Sonar (SSS) data often suffers from geometric distortions and intensity inconsistencies due to AUV movements, terrain undulations, and slant-range effects. This section reviews crucial preprocessing techniques like slant-range correction, which converts acoustic slant range to true horizontal ground range, and geometric distortion correction, which aligns acoustic data with AUV pose information to reconstruct accurate target imaging. Advanced methods include bottom tracking using AI-driven semantic segmentation and image mosaicking to create composite survey maps.
Autonomous Target Detection
Seabed target detection faces challenges like small sample sizes, lack of texture information in sonar images, and computational constraints on AUVs. This section compares traditional methods, relying on manually designed features and statistical modeling, with deep-learning based strategies. Deep learning approaches leverage Convolutional Neural Networks (CNNs) for automatic feature extraction, often employing transfer learning, few-shot learning, or data augmentation to overcome data scarcity issues, enabling more robust and accurate target recognition.
Path Planning Strategies
Effective path planning is critical for AUV-based seabed surveys, balancing coverage efficiency, energy consumption, and target identification. This section covers traditional predetermined paths (lawnmower, spiral) for wide-area coverage and data-driven adaptive methods that use environmental feedback and target probability maps for optimized path selection. Advanced strategies involve multi-AUV cooperation, multi-view optimization for 3D reconstruction, and adaptive switching between coarse and fine survey modes for high-precision tasks.
