Photometric stereo synthesizes a composite, enhanced-contrast image from a series of source images, using a powerful tool found in Matrox Imaging Library (MIL)—and soon, Matrox Design Assistant—software. This tool highlights changes to surface curvature and material, revealing raised or recessed defects like dents or scratches, or features like stamped or embossed symbols.
Join Pierantonio Boriero, director product management at Matrox Imaging, for a Q&A on how photometric stereo synthesizes images, reveals surface defects and anomalies, and employs appropriate directional lighting for optimized image capture.
