Abstract. Over the last years, High-Definition (HD) video cameras have made visual inspections of subsea assets more efficient and a source of massive and critical information. But in many cases, this visual information is incomplete without dimensions and geometry and can be biased by the wrong optical perspective, the lack of scale, or bad water clarity.

This paper will describe the development of a new Technology, called Video Laser Scan™ (or VLS™), based on the combination of Photogrammetry and Laser Triangulation techniques, that provides additional Intelligence to such subsea inspections. In addition, we will highlight the innovation recently brought by Artificial Intelligence and 3D Holograms.
