Objectification of surface test methods through image processing

摘要

The invention relates to the objectification of surface test methods through image processing. Information z(x, y) is measured and recorded for each image point (x, y) of the measuring field of an examined specimen surface, and resultant magnitudes are calculated therefrom. An objective correlation of these resultant magnitudes occurs with a scale of so far subjectively measured quality characteristic numbers of a characteristic of the examined specimen. A method for an objective evaluation of a bending edge of metal bands and for a wear test on metal bands is described in detail.
