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…
Performance Assessment of Feature Detection Methods for 2-D FS Sonar Imagery
Hitesh Kyatham, Shahriar Negahdaripour, Michael Xu +3
Underwater robot perception is crucial in scientific subsea exploration and commercial operations. The key challenges include non-uniform lighting and poor visibility in turbid env…
Object Modeling from Underwater Forward-Scan Sonar Imagery with Sea-Surface Multipath
Yuhan Liu, Shahriar Negaharipour
We propose an optimization technique for 3-D underwater object modeling from 2-D forward-scan sonar images at known poses. A key contribution, for objects imaged in the proximity o…
MARVIS: Motion & Geometry Aware Real and Virtual Image Segmentation
Jiayi Wu, Xiaomin Lin, Shahriar Negahdaripour +2
Tasks such as autonomous navigation, 3D reconstruction, and object recognition near the water surfaces are crucial in marine robotics applications. However, challenges arise due to…
