1. A system comprising: a 3D digitizer comprising an attached light source and a sensor to obtain a plurality of images of an object and generate data representative of a surface of the object; and a processing system in communication with the 3D digitizer to receive the plurality of images and the data representative of the surface of the object, the processing systems generating a textured 3D model of the object from the plurality of images and the data representative of the surface of the object, where the processing system adjusts an intensity of the plurality of images using an intensity function that compensates for effects of the attached light source and maps textures from the plurality of adjusted images to corresponding points in the 3D model, each visible point in the 3D model corresponding to a texture from one of the plurality of images.
