Recently, methods for measuring kinematics in mechanical processes based on digital image processing have been gaining in popularity. These methods allow non-contact and simultaneous measurement of a large number of degrees of freedom. Also, with the development of information technologies, the availability of software tools in the form of web-based applications is increasing, which eliminates the need to install the software. We have presented the theoretical background of methods for identifying displacements based on digital image processing and tools for creating web applications. We also researched MIMO systems and developed a program to compute the frequency response function estimators of such systems and show the different effects on the estimator result. The main result of the thesis was a web application for computing displacements of structures based on digital image processing with the possibility of calculating frequency response functions.
