Originální abstrakt
The aim of this paper was to test the suitability of using photogrammetry for metal additively manufactured parts with respect to metrology applications. Another aim was to test the influence of the chosen parameters on the quality indicators of the measurement data and the suitability of using single and stereo camera setups. The parameters of the measurement system whose influence was assessed were the exposure time, number and resolution of images taken. The individual measurements were evaluated in terms of the computational complexity, number of points obtained, part coverage ratio and the standard deviation of the distances of all points from the surface of the reference model. By comparing the results, a matrix of optimal parameters for the given part types was created and further trends describing the influence of individual parameters on the results were observed. The experimental comparison performed shows the possibilities of photogrammetric measurements, gives an idea of the appropriate parameters settings and has also shown that photogrammetry can be a competitor to fringe projection scanning of metal additively manufactured parts. The main drawback of this method is still the computational time and the need for a distinctive surface texture.
