    摘要: A system for estimating the specular roughness of points on a surface of an object may include a lighting system, an image capture system and a computer processing system. The lighting system may be configured to illuminate the surface of the object at different times with different illumination patterns. Each illumination pattern may illuminate the surface from a plurality of different directions and form an intensity gradient having an order of no more than two. The image capture system may be configured to capture an image of the surface of the object when illuminated by each of the different illumination patterns at each of the different times. The computer processing system may be configured to compute the specular roughness of each point on the surface of the object based on the images captured by the image capture system.
