Application of the three-dimensional digital image correlation technique (3D DIC) to the accurate measurement of full-field surface profile of a 730 mm-diameter carbon fibre composite satellite antenna is investigated in this article. The basic principles of the 3D DIC technique are described. The measured profile was compared with the one measured with a three-dimensional coordinate measuring ...

Many types of three dimensional mechanisms (3Dmechanism) are used in modern industry. Specially, in automation technology, product engineering and robotics, 3D-mechanisms play the key roles of complicated manipulation, 3D positioning and 3D measurement. Usually, the repeatability of 3D-mechanism is tested and evaluated. However, when we use 3D-mechanism in wide purposes and in wide conditions, ...

This paper describes a multi-sensor measuring system for reverse engineering applications. A sphereplate artefact is developed for data unification of the hybrid system. With the coordinate data acquired using the optical system, intelligent feature recognition and segmentation algorithms can be applied to extract the global surface information of the object. The coordinate measuring machine (C...
