Graduate of technical higher education (minimum master's / doctoral / doctoral student), experience in 3D modeling, 3D scanning, UAV piloting, digital photography and generation of 3D models using the photogrammetry method.
The position is open in the frame of project ass digitization of cultural heritage: between myth and reality. Evaluation of the accuracy of 3D models generated using photogrammetry method in the case of cultural heritage.
The main objective of the project is to evaluate the performance accuracy and uncertainty of photogrammetry in the case of digitizing cultural heritage represented by artefacts and monuments using standalone and cloud software. From the scientific point of view, this research will be among the first which will evaluate the accuracy of photogrammetry in comparison with state of the art structured light and laser scanners using “calibrated reference gauges”. Most of the current research is focused on comparison between photogrammetry and terrestrial laser scanners, and additionally we will use handheld scanners and state of the art Coordinate Measuring Machines (CMM). Photogrammetry results will be evaluated in the laboratory using “reference gauges” and in situ by using real artefacts and monuments. Our experiments will be focused on software which uses the structure from motion (SfM) algorithm and monocular photogrammetry. In the first stage of the project a series of “reference gauges” will be designed and manufactured for studying the accuracy of photogrammetry. This gauge will include standard geometric elements which can be recognized automatically in reverse engineering software. In the second stage of the project the experiments will be conducted in order to determine the contribution to the uncertainty budget for each factor that can affect the results: different camera set-up (ISO, aperture, lens, etc.); distance to object; light condition; color versus black & white; with imagine stabilization on and off; insufficient overlap of the imagines; resolution of the imagine and shooting positions. In the third stage of the project for each parameter studied there will be estimated the contribution to the uncertainty budget in a manner similar to that of CMM measurements. Based on the values obtained a series of recommendations will be made in order to reduce the negative effects of each parameter.
