Camera-Sonar Combination for Improved Underwater Localization and Mapping
Cardaillac, Alexandre; Ludvigsen, Martin (Journal article; Peer reviewed, 2023)Taking advantage of the complimentary properties of sonars and cameras can improve underwater visual odometry and point cloud generation. However, this task remains difficult as the image generation concepts are different, ... -
A Communication Interface for Multilayer Cloud Computing Architecture for Low Cost Underwater Vehicles
Cardaillac, Alexandre; Ludvigsen, Martin (Journal article; Peer reviewed, 2022) -
Marine Snow Detection for Real Time Feature Detection
Cardaillac, Alexandre; Ludvigsen, Martin (Peer reviewed; Journal article, 2022)Underwater images are often degraded due to backscatter, light attenuation and light artifacts. One important aspect of it is marine snow, which are particles of varying shape and size. Computer vision technologies can be ... -
Modular Multi-Sensor Fusion for Underwater Localization for Autonomous ROV Operations
Scheiber, Martin; Cardaillac, Alexandre; Brommer, Christian; Weiss, Stephan; Ludvigsen, Martin (Chapter, 2022)Localization filters for underwater vehicles are mostly tailored for specific sensor suites, environments, or missions. It is also well known that the underwater environment can evolve over time and throughout the mission, ... -
Semantic Segmentation in Underwater Ship Inspections: Benchmark and Dataset
Waszak, Maryna; Cardaillac, Alexandre; Elvesæter, Brian; Rødølen, Frode; Ludvigsen, Martin (Journal article; Peer reviewed, 2022)In this paper, we present the first large-scale dataset for underwater ship Lifecycle Inspection, Analysis and Condition Information (LIACI). It contains 1893 images with pixel annotations for 10 object categories: defects, ... -
Towards autonomous underwater navigation and perception for end-to-end ship hull inspection
Cardaillac, Alexandre (Doctoral theses at NTNU;2024:68, Doctoral thesis, 2024)This thesis presents an innovative and integrated solution for end-to-end underwater ship hull inspection using a small and low-cost Remotely Operated Vehicle (ROV). In a world where maritime activities have significant ...
