NUMERIC ENGINEERING'S PATENTED COMPUTER VISION TECHNOLOGY

Numeric Engineering has a patented computer vision application that is able to track 6 degrees of freedom (DOF) motions of structures in challenging offshore environments (Patent Number: US 11,461,906 B2).

Computer vision is a field of artificial intelligence (AI) that enables computers and systems to derive meaningful information from digital images, videos and other visual inputs — and take actions or make recommendations based on that information.

Indirect estimation of the physical displacement of a component of an offshore structure may be used to assess the structural integrity of the component. For example, physical displacement of a component of an offshore structure may be estimated indirectly from acceleration measurements collected from accelerometers and/or strain measurements from strain gauges attached to the component. Laser scanning may also be used in some applications to estimate dynamic displacements of a component of an offshore structure at a significantly higher cost, system complexity, power consumption, and excessive data generation relative to other indirect techniques such as accelerometers and strain gauges. Consequently, laser scanning is generally only suitable for short-term solutions. In yet some other cases, visual inspection of a component via a remotely operated vehicle (ROV) or personnel of the offshore structure may be relied on to estimate physical displacements. A single high resolution subsea camera and a pre-determined image pattern that is attached on the location of interest may be sufficient to track the movements of the object of interest at a reliably high accuracy.
