AbstractThis report documents the findings and the results of an engineering exercise to develop a process to measure the corrosion depth of buried samples from their scanned images before and after burial. The recommended method consists of 5 steps which combine the power of a Konica Minolta scanner, PolyWorks and software developed in Matlab. PolyWorks is mainly used as a human interface for manipulating and aligning point cloud data sets. The use of PolyWorks reduces software development to a minimum. Software developed in Matlab is mainly for image transformation and corrosion depth/volume calculation.
