Lou, Shan, Jiang, Xiangqian and Scott, Paul J. (2014) Applications of Morphological Operations in Surface Metrology and Dimensional Metrology. Journal of Physics: Conference Series, 483. 012020. ISSN 1742-6596
Abstract

In contrast to the widely used mean-line based evaluation techniques, the
capabilities of morphological methods are not fully recognized in practice. Morphological
operations, e.g. dilation, erosion, closing and opening, are useful tools in surface metrology and
dimensional metrology. This paper presents a variety of novel applications of morphological
operations in association with several of existing critical cases to demonstrate their usability
and capability. These applications include scanning process analysis, real mechanical surface
reconstruction, freeform surface deviation evaluation, open surface and roundness filtration,
form approximation, contact phenomenon simulation, establishment of uncertainty zone for
continuous surface reconstruction and stratified functional surface evaluation.
