| The primary objective of this thesis is to evaluate the performance of state-of-the-art (SOTA) algorithms for the registration of concrete scan data. The focus is on assessing their accuracy, limitations, and robustness, particularly in the context of scan alignment and integration. A key outcome should also include an analysis of scan quality and a characterization of the scanner itself.
Dataset Description: The dataset consists of 15 representative videos in 4K resolution. Each video captures a full 360° rotation of a concrete sample (2.1 cm in diameter) under two illumination conditions: low-angle lighting (up to 15°) and nearly perpendicular lighting (above 82°). Thesis Tasks: - Register all video frames into a single 3D matrix of pixel intensities through image superposition. - Analyze the frame transformations, distinguishing between meaningful signal (e.g., controlled sample rotation) and noise (e.g., vibrations, lens distortion). - Identify suitable metrics for evaluating registration quality in the absence of ground truth data. - Summarize findings and propose recommendations for future research and improvements to the scanning system. Expected Deliverables: - Functional tools for converting video scans into aligned 3D matrix representations with applied transformations. - A comprehensive report detailing the methods used, their performance across the dataset, and insights into algorithm strengths and weaknesses. - Determination of the upper useful resolution limit in relation to achievable registration precision. - Recommendations for future research directions and potential adaptations or improvements to the scanning system. |

| The lifecycle of concrete has become a highly relevant research topic, particularly due to two key developments. First, the Fukushima incident highlighted the need to better understand how concrete properties change under intense gamma and neutron irradiation. Second, the extension of operational lifespans for nuclear power plants—especially across Europe—has intensified the demand for thorough evaluation of irradiated construction materials. In this context, the need for advanced concrete testing methods, particularly under irradiation exposure, has grown significantly.
To address this need, our team is developing a scanning system capable of efficiently processing a large volume of irradiated concrete samples with minimal manual handling. A fundamental component of this system is the production of high-quality, high-resolution scans of concrete samples under varying lighting conditions. |
