Paired Sonar / Optical Video Dataset

<p>This dataset was collected for L. Viney's undergraduate engineering honors thesis at UNSW in collaboration with Reach Robotics.&nbsp;<br>It features paired forward facing multibeam sonar and optical video recordings gathered using an Oculus M series sonar mounted on a FUSION ROV in Sydney Harbour.&nbsp;<br>Reach Robotics retains rights and ownership of the data, which is released under a Creative Commons CC BY-NC-SA license.</p> <p>Dataset Contents<br>Sonar Recordings: Proprietary-format sonar files compatible with Oculus Viewer software.<br>Optical Video Recordings: Synchronized optical video files paired with each sonar recording.<br>Bounding Box Labels: A limited number of sessions include bounding box annotations for sonar data, provided as CSV files.</p> <p>Prerequisites<br>To view and analyze the sonar data, download the Oculus Viewer software from Blueprint Subsea:<br>https://www.blueprintsubsea.com/oculus/support</p> <p>Folder Structure<br>The dataset is organized with each session containing both sonar and optical video files. Sessions with annotations also contain CSV files for bounding box labels.</p> <p>dataset/<br>├── session1/<br>│ &nbsp; ├── sonar.oculus<br>│ &nbsp; ├── optical.mp4<br>│ &nbsp; └── labels.csv &nbsp; &nbsp; &nbsp; &nbsp;# Bounding box annotations (if available)<br>├── session2/<br>│ &nbsp; ├── sonar.oculus<br>│ &nbsp; ├── optical.mkv<br>│ &nbsp; └── labels.csv &nbsp; &nbsp; &nbsp; &nbsp;# Only in labeled sessions<br>└── README.md</p> <p><br>Data Annotations<br>Annotations are provided as CSV files in specific sessions. Each CSV file includes bounding box coordinates for objects in the sonar frames, with columns typically structured as:</p> <p>frame_id, object_1_x_min, object_1_y_min, object_1_x_max, object_1_y_max, object_2 ...</p> <p>Usage<br>Sonar Data: Use the Oculus Viewer software to load and view .oculus files.<br>Annotations: Use the CSV files for supervised learning or object detection by overlaying bounding boxes on sonar data.<br>Optical Video: Optical video files are compatible with standard video analysis tools.</p> <p>License<br>This dataset is licensed under the Creative Commons CC BY-NC-SA license.
