Abstract
Robotic systems are at forefront for doing dull, dangerous and dirty tasks in place of humans. Th e days of employing humans
to risk their lives for inspecting infrastructure are numbered. In this presentation, the author will talk about the laser optics
technology he has developed in his research lab for: (1) Inspecting tubulars in Evraz, one of the largest pipe manufactures in the
world, (2) Non-intrusive 3D profi ling of the deposited material in pipes for cleaning purposes, and (3) In-motion image-based
3D modeling of the vehicles passing through a smart inspection station. Th e common tread among all the aforementioned
projects is the use of imaging sensors and structured light (i.e., collimated laser fringes) for metrology and inspection. A
guideline for design of an omni-directional imaging system yielding optimal spatial resolution using a Catadioptric camera
and a laser ring will be provided. Th is will fi t into the image-based QC of tubular at a high resolution with a very modest
budget. Furthermore, author will provide details on 3D profi ling of the deposited material in pipes and also in-motion imagebased
3D modeling of vehicles using a perspective camera and two collimated laser lines
