Shape-from-Shading – Illuminating 3D Surface Inspection with Integrated Multi-Light Control

Shape-from-shading (SFS) is a computer vision technique that draws upon light and shadow patterns to reconstruct an object’s 3D shape from a single 2D image. As an inspection tool, SFS can be highly effective at identifying and measuring surface defects on an object such as scratches, dents, pores, and grinding marks that are often invisible in typical machine vision setups.
