摘要：In automotive industry, an increasing demand on 3D surface reconstruction from high-speed camera images can be observed, e.g. in car safety testing environments. The paper deals with the automatic photogrammetric measurement of free-form surfaces from synchronous stereo and multi-image sequences as they are required for dynamic area-based deformation analysis. Firstly, instrumental solutions for synchronous acquisition of multi-image sequences are discussed. For surface reconstruction different image-based matching methods are evaluated and compared with an object-based matching method based on the FAST Vision principle. For each step of the sequence, a three-dimensional surface model is generated, that can be enhanced to a 4D deformation model with time as fourth dimension. For visual analysis the photogrammetrically oriented image sequences can be resampled to sub-pixel accurate anaglyph movies
