In the paper vision techniques connected with the static and dynamic parameter measurements of constructions are presented. Displacements of measurement points of the analyzed object resulting from a load were computed by means of image correlation coefficient. Image registration techniques were introduced to increase the flexibility of the method. The application of homography matrix enabled the deflection field to be obtained from two images of the structure acquired from two different points in space. Introduction of image mosaicing techniques increased the accuracy of the measurement system.
The mentioned second approach enables obtaining amplitudes of vibrations of analyzed scene objects (measurement points) along with their structure based upon data derived from fast one or more digital cameras. For this purpose procedures and algorithms for two and three-dimensional image processing employing epipolar geometry were developed. As a result two- and three dimensional measurements of vibration amplitude components of selected construction points.
The developed methodology and experimental results obtained from tests made on synthetic data generated by developed software tool are discussed.
