The dataset comprises a set of images that includes different man-made objects considered critical in underwater operations. Anchors, buoy, chain, flutuation module, 3D marker, mine and pipeline were selected to represent some common objects that are presented in water scenarios. The data were acquired with a monocular camera in diverse conditions of the luminosity and perspectives of the objects. Moreover, the objects were captured in pure and turbid water and with white and coral reef background, to simulate real environments. Nowadays, the online available datasets are incomplete for this type scenarios and so, datasets as the UWObjects@CRAS are important to validate new perspectives and to answer to challenges, because to allow the development and validation of systems able to object identification, manipulation and obstacle avoidance, for example.
