Abstract [en]

This master thesis describes the development of an application for texture mapping. Itspurpose is to simplify quality assurance for carbon fiber workpieces. Thermographic images are captured of the same and mapped to a 3D model, this way it can be examined ina convenient and interactive manner. The Direct Linear Transformation (DLT) is used for2D-3D assignments. Contents are the mathematical background of the DLT, the graphicalvisualization via OpenGL and the detailed explanation of the mapping process. The visualization part dives deep into the components of a graphics engine and explains how toimplement decent and efficient scene rendering. CUDA and OpenCL are addressed as wellto demonstrate the possibilities of performance improving for highly parallelized tasks. Aconcluding experiment is conducted, proving operational reliability and only small deviations. The reasons for some deviations between the mapped images are discussed andrecommendations for solving them are offered.
