Summary:A machine vision-based method and system for locating an object within a scene are provided. The method includes uniformly illuminating a target surface of the object within the scene with light having an intensity within a relatively narrow range of wavelengths such that the light overwhelms the intensity of ambient light within the narrow range to obtain reflected, backscattered illumination. The method also includes sensing brightness of the surface due to a diffuse component of the backscattered illumination to obtain brightness information. Backscattered illumination from the target surface is inspected to obtain geometric information. Rotationally and positionally invariant surface albedo of the object is computed based on the brightness and geometric information. The surface albedo and the geometric information may then be used by a matching algorithm.
