Integrated precision evaluation method for three-dimensional optical measurement system

摘要

An integrated precision evaluation method (IPEM) for evaluating the capabilities of sophisticated optical measurement systems is proposed. The method, which has the advantages of the VDI/VDE2634 guidelines and the Standardization Project for Optical Techniques of Strain measurement procedure, is developed on the basis of three-dimensional (3D) optical measurement technology and statistical principles. The application of the IPEM to a combination of an in-house developed 3D optical measurement system and an in-house developed photogrammetry measurement system is investigated for the case of measuring features on a large-scale waterwheel blade. It is shown that the proposed method is appropriate and feasible for application in manufacturing industries.
