Abstract

The basic steps of automatic surface reconstruction from digital images are briefly outlined, with attention to the factor determining the final quality of the process. The reconstruction of the deformation surface of a metal plate stressed to failure is then presented. The automatic search of the interesting points, the identification of conjugate pairs, and the least squares matching are described, outlining limits and characteristics peculiar to the chosen method. The results are also discussed in comparison with a previous photogrammetric survey by analog imagery.
