Early prototype

A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

3D RTI Images taken with our system can be used for quick high resolution 3D scanning; for example quick quality analysis and digitisation of objects.


Our 3D RTI Dome allows us to relight photo's after they are taken, and allows us to construct a 3D image and model the surface reflectance. We do so by computing image's appearance as a function of the position of the light on the object.


Our method will allow rapid capture in 3D, that can be used for shape, material or quality analysis. Such RTI images are easy to publish on-line and allow relighting of objects. We intend to use it to scan the entire numismatic collection of the Federal Reserve in the USA.
