In this paper the development of the Sub-pixel gray-scale Hough transform as a method of detecting the positions of lines is presented. The algorithm is part of an electronic interface created for the Nikon 6B/6D autocollimator. This interface allows for an increase in final resolution of measurements and a reduction of the vignetting and distortion effects produced by this optical instrument's lenses. The electronic interface consists of a Basler ACE HD camera and its positioning devices, and a computer with a sub-pixel digital image processing package.
