Measurement strategy impact on dimensional inspection by portable camera-based measuring systems

摘要

In dimensional inspection of large objects, portable measuring systems are greatly involved in a wealth of applications, such as automotive, motorsports and aerospace industries. Metris K-series Optical CMM (Coordinate Measuring Machine) system is one of the metrology solutions with relatively high accuracy and flexibility. This paper focuses on measurement strategy via repeatedly measuring a length using Metris K610 camera system. The paper proposes a link between measurement strategy and the system performance that can be achieved. The result of the statistical analysis are also given based on the uncertainty propagation of the CMM.
