The Arius three dimensional color laser scanner is based on 17 years of research by the National Research Council of Canada (NRC/CNRC) Institute for Information Technology. The NRC-IIT research team has built an international reputation and provided leadership in many key areas of research linked to the use of 3D technologies for cultural heritage and 3D imaging metrology.
The system consists of a laser scanner and a motion control system for moving the camera. The system characterizes each measurement point according to its color and location in 3 dimensional space using the principles of high resolution, low-noise, three-color laser triangulation and optically-synchronized scanning.
Each measurement point is described by three geometric values as XYZ and three reflectance values as RGB collected simultaneously from the target surface. Scanned data is recorded and processed by proprietary software to create high-quality 3D color images of real-world objects.
