Claim Text:
1. A method for mapping a sensor pixel array to an illumination pixel array according to a surface, comprising: forming a group map by assigning each pixel in a plurality of pixels on the sensor array to a corresponding group of an ordered set of groups on an illumination pixel array, wherein each group is defined by a set of p adjacent pixels on the illumination pixel array and wherein each group is defined by a group boundary by: projecting and recording at least p different multiline images onto the surface, wherein each multiline image projects a line within each group; correlating lines in the recorded multiline images with lines in the projected multiline images according to the group map; and using the recorded at least p multiline images to form a surface contour image of the surface, wherein n and m are integers greater than or equal to 1 and p is an integer greater than or equal to 2.
