Calibration and Comparative Analysis of Forward-Looking Sonar and 3D Sonar for Enhanced Underwater Object Recognition
Aditya Penumarti, Khanh Dong, Zi-Hao Zhang +6
Sonars generate a significant amount of noise. With the advent of new technology capable of producing full 3D point clouds, the noise is amplified in sparse point clouds, making it…
uScenes: A Multimodal RGB and 3D Sonar Dataset for Underwater Robot Perception
Trung Tien Dong, Zhenqi Wu, Aditya Penumarti +4
Robust perception is essential for the deployment of autonomous underwater robots. However, optical cameras become unreliable under poor illumination and backscatter. Forward looki…
A Hybrid Model-Based and Model-Free Framework for Active Multi-View Viewpoint Optimization in Sonar Target Recognition
Yongkyoon Park, Jane Shin
This paper presents a hybrid model-based and model-free framework for active multi-view target recognition using forward-looking sonar. A convolutional neural network (CNN) provide…
Point Cloud Structural Similarity-based Underwater Sonar Loop Detection
Donghwi Jung, Andres Pulido, Jane Shin +1
In this letter, we propose a point cloud structural similarity-based loop detection method for underwater Simultaneous Localization and Mapping using sonar sensors. Existing sonar-…
