1. A method of 3D measurement, evaluation and grading system for fabric/textile structure/garment appearance, the method comprising using a fixed digital camera positioned above a piece of the fabric, shining at least two different parallel light beams from inclined directions on to the surface and capturing different reflected images of the surface with the camera, analysing the captured images to derive values of parameters of the surface based on the intensities of light reflected from a number of evenly distributed points of the surface.
