Use of close range photogrammetry for documentation of structure parts deformation monitoring

Popis výsledku v původním jazyce

This paper presents an application of photogrammetrical methods for measuring the deformation of timber beam at sequential loading. Several load conditions were documented using correlation techniques and intersection photogrammetry. The progress of deformation was measured with a non-contact photogrammetrical method with the use of the image correlation technique. In this first experiment, a calibrated digital middle format camera Pentax was used for taking of photos. Agisoft Photoscan software was used for the deformation documentation. In the second experiment, three calibrated digital high resolution Canon cameras were used. The cameras were installed about 2 m from the measured object with the camera base approx. 3 m away. A computer controlled both cameras remotely and the images were saved to the hard drive in raw format. The images that were taken were synchronized in several intervals. On the object, cca 50 measured points were monitored for dynamical deformation. Photomodeler software was used in this case. As comparative models, measurements by the precise laser scanner Surphaser were done such as the direct measurement of deformations by potentiometers. The outputs shown, which all used non-traditional technology, are good enough for deformation measurement in sub-mm range.
