ABSTRACT
Load tests of building components are mostly metric documented by the methods of
length difference measurement. The most often used instruments are various types of
dilatometers. Modern types of electronic dilatometers offer excellent precision about
level of micrometers. But problems such: contact measurement, measurement only one quantity (length), limited number of sensors located on object, need of cabling,
possibility of instrument damage, high price of instruments, influence of other physical
quantity of object (humidity, temperature) can be well eliminated by the non-contact
optical methods. In our contribution we use methods of digital photogrammetry for
documentation of static deformation in discrete epochs as well as videogrammetry for
documentation of dynamic deformation processes. Accuracy at submillimeter level was
reached and advantages of this measurement techniques are commented.

Keywords: videogrammetry, building components, dynamic deformation processes.
