Interest in computer vision reconstruction techniques using 2D forward-looking sonar (FLS) imaging for underwater environments with poor visibility has grown significantly over the past decade. In addition, an opti-acoustic stereo imaging paradigm developed more than 20 years ago is gaining renewed attention for its potential in novel scene reconstruction. With advances in deep learning frameworks and digital twin technology, this work explores the fundamental principles of computer vision, sonar image formation and processing, and sensor fusion techniques that combine 2D sonar data with optical imagery to address complex underwater perception challenges.Presenters
