摘要:The paper presents a modular photogrammetric recording and image analysis system for determining the 3D shape of Ethylen- TetraFluorEthylen-Copolymer (ETFE) foils, including their evolution over time when put under increasing air pressure. Determining the time-variable 3D shape of transparent material imposes a number of challenges – especially, the automatic point transfer between stereo images and, in temporal domain, from one image pair to the next. We developed an automatic approach that accommodates for these particular circumstances and allows to precisely reconstructing the 3D shape for each epoch as well as determining 3D translation vectors between epochs by feature tracking. Examples including numerical results and accuracy measures prove the applicability of the system
