This report highlights the potentials and capabilities of a robotised fringe projection system. Its objective is to verify the performance of such a system located in Advanced Remanufacturing and Technology Centre (ARTC), in terms of accuracy and repeatability. The available types of measurement techniques in the market are also studied upon. Definitions for the digitising needs are discussed as well. By understanding the working principle of a fringed projection system, an artefact with intended features are designed and fabricated. The measurements done on the artefact is used to make comparison between the robotised fringe projection system and a highly précised Coordinate Measuring Machine (CMM) instrument. Finally, from the data evaluation, a quantitative understanding of the system’s performance is obtained. The results show that the robotised fringe projection system’s performance is comparative to the CMM. The ATOS Triple Scan is capable of giving high precise non-contact measurement with accuracy of 41 μm and standard deviation of 23 μm. For benefit of future measurement, good practices and recommendations during the course of this study are noted and tabulated.
