In the context of developing automated optical inspection system, this work brings into focus the aspect of de-velopment of evaluation algorithms for thickness distribution extraction from the object model reconstructed after surface scanning. Within this work an algorithm for the evaluation of local differences between two triangle meshes is presented. The pair of triangular meshes is representing the front and backside of a scanned 3D-object. The resulting array of differences vector corresponds to the shortest local distances (i.e. local thickness) between sides of object.
