Abstract
In the paper we present different problems which may occur during measurements of displacements/strains and shape of engineering objects including the necessity of recalculating of coordinates of measurement results and performing measurements in climate chambers. The first example refers to metal plates segments that are objects of complex geometry and are di cult to be measured with a single 3D DIC setup from only one direction, the second one is a composite cylindrical container with programmed faults, while the third one is a mirror subjected to thermal load in a climate chamber. Presented applications shows a flexibility of the method in different measurements tasks, however in each of these cases, an individual approach to experiment preparation and planning was required.
