Peculiarities of flat cam measurement by results of digital photo shooting

Abstract

During technical diagnosis it is often needed to determine object dimensions remotely by results of some optical data. The digital photography is the perspective method for non-invasive measurement of industrial machinery objects. But the peculiarities of equipment and digital photo process bring some important restrictions and constraints to measurement process. We tried to explain the peculiarities and unite the advantages of different methods of photographical non-invasive measurement for easy flat cam mechanism to recover the cam profile and estimate precision of measurements. © Springer Science+Business Media B.V. 2010.
