Abstract
This paper presents an approach for the determination of surface parameters based on a
mesh calculated from identified features. The resulting mesh-based parameters are used to
assess the homogeneity of the feature distribution on the surface. The preparation of the
data is a prerequisite for creating the mesh. The input data of a surface has to be processed
in such a way that the features can be identified, which are the valleys for the examined
blasted surfaces. For this, areal measurements and the application of filters are necessary to
separate the features. In the next step a mesh is created. The simplest form is a triangular
structure, which has already been used to describe the homogeneity of surfaces with
particles. Based on this, various characteristics are evaluated and analyzed statistically. The
method has been applied to four surfaces blasted with different blast media as an example.
