摘要: A method of copying a three-dimensional surface having X, Y, and Z dimensions forms a translucent impression of the surface to be copied and then captures a two-dimensional image of the translucent impression. The captured image has X and Y dimensions and a grayscale value for each X, Y coordinate of the image. Then, the method converts each grayscale value of the image to a Z height value, thereby generating a digital file of X, Y, and Z values. The digital file may then be provided as an input to a numerically controlled machine, which can be operated to reproduce the surface to be copied. The method of the present invention finds particular application in digitizing handcrafted emboss dies and the like.
