Three-dimensional surface test with “Shape-from-Shading“
15.03.2007 - Photonik international /2007 | [ deutsche Version lesen ]
By analysing the shading of continuous surfaces with smooth contours, information on three-dimensional object shapes can be extracted. Using advanced algorithms and special illumination geometries, braille dots and similar types of embossed structures may be checked in an easy and inexpensive way.
