3D Imaging and Modeling Metrology
Main Objective
The long term objective is to perform research in three-dimensional (3D) imaging and modelling metrology that will lead new standards and traceable 3D measurements. This will be accomplished by expanding the use of Digital 3D Imaging and Modeling technologies and developing improved non-contact visual inspection methods in support of NRC’s R&D priorities in Health/Wellness, the environment and in the strategic sector of Manufacturing. These priorities are important for Canadian industries that are competing in a global context.
Context
In recent years, sensors and algorithms for digital three-dimensional (3D) imaging and modeling (3D imaging for short) of real objects and sites have received significant attention, not only at the academic levels, but also increasingly as an important tool for documentation, analysis, inspection and visualization in application fields as diverse as manufacturing, construction, medical and cultural heritage.
Many of the traditional measurement instruments are being complemented with or even replaced by 3D imaging scanners based on either triangulation or time of flight technology to measure complex freeform surfaces. The opportunities for increased productivity and quality using the latest 3D imaging technologies are visible in many sectors. Unfortunately, wide spread adoption is hindered by the fact that many industries are unwilling to invest in these technologies because of a lack of standards, reliable inter-comparison information, adequate training in universities and colleges and independent test laboratories.
Supporting new advances in manufacturing
Freeform metrology will need to support rapidly developing advances in manufacturing processes by establishing a much needed specialized and impartial metrology measurement facility, transfer artefacts, traceability mechanisms and a knowledge-base centre at NRC-IIT. This sudden change in process design and quality assurance practices needs to be addressed by a research organization like NRC. In particular, targeted research and applications are required in areas like freeform metrology using 3D imaging. We have at VIT the demonstrated expertise in 3D imaging, modeling and visualization. Furthermore, having already a clear R&D plan to promote and create synergy in this area of national importance is a definite advantage to help Canadian industries compete in a global context.
NRC-IIT facilities and expertise
The 3D imaging and modeling metrology research project includes an environmentally (temperature as per ISO 1) controlled Metrology Laboratory facility as well as different sub-projects and activities with NRC institutes, industrial collaborators and external international partners. NRC-IIT’s aims at developing standards with industrial partners and new optical measurement methods to further develop the "next generation" of 3-D technology. Along with our own laser scanners designed and built at NRC-IIT, state of the art high-quality metrology equipment and other laser scanners are also used.
NRC-IIT is currently collaborating with a number of (National Metrology Institute) NMIs like the National Institute of Standards and Technology (NIST), USA and the National Physical Laboratory (NPL), UK. The NRC-Institute for National Measurement Standards (INMS) Dimensional Metrology group is also a partner in our research project. A number of research institutions are already collaborating with us (e.g. UCL, UK) and many Canadian companies.
