DimEye Corp. Introduces the Revolutionary VLS (Video Laser Scan) to the Subsea Survey IMMR audience in Galveston Texas (November 2013). VLS™ (Video Laser Scan) by DimEye Corp. is a revolution in Optical 3D Measurement. VLS Provides High Definition Visual Inspection, As-Built 3D Modeling of Industrial/Subsea Equipment, 3D High Density Mapping of Deformations and Defects (for example: Cracks, Dents, Bulges, Corrosion) VLS™ is a unique combination of photogrammetry and Laser Techniques which provides the Advantages of both technologies without the disadvantages. VLS™ can also be operated by your existing technicians. VLS™ is a High Accuracy Metrology Tool Linked to NIST (National Industry of Standards and Technology) that provides High Redundancy through volume of data collected (1000s of stills can be captured from HD video in seconds rather than individual photos taken manually at each location). VLS™ provides Reliable Accuracy Estimates (thanks to advanced processing and calibration algorithms developed by DimEye after years of industry experience in multiple measurement environments and scenarios).
