The Shipwreck-Dataset
The Shipwreck-Dataset was found to contain several synchronization errors between the video data and the sonar data. We prefer to temporarily remove it in order to make the necessary corrections before putting it back online or releasing a new dataset. We apologize to any colleagues who may have been affected by these synchronization errors.
Acoustic images, monocular vision, IMU and depth
"Basile" ROV
