Abstract
3D photogrammetry measuring systems using LED targets and CCDiCMOS
Cameras are gaining wider application in metrology fields. They are often
used as portable CMMs in different industry sectors. Because of the
similarities between these camera systems and conventional CMMs in
dimensional measurements, the accuracies of these optical systems are
normally specified using the well-established methods for conventional
CMMs. However, the analytical and experimental results introduced in ths
paper show that the current accuracy specification methods are not well
representing the accuracy of these camera systems. They show quite different
field performance than conventional CMMs, due to the systems' specific
characteristics. As a possible solution, in the latter
