Abstract

In order to adapt to the trend of surface quality assessment, the 3D topography measurement becomes more and more important. In metallurgy industry, the topography of roller affects that of cold-rolled steel sheet mainly, which makes it necessary to measure the topography of roller. On the base of traditional light section method and light scanning technique, the triangular light beam scanning method is designed and adopts linear structured light to scanning test surface and acquire height data through demodulating the surface 3D information carried from observation field. Applied with the TLBS surface topography measuring system, some 3D topography examples are given to verify the correctness and feasibility of it.
