Abstract

A method of performing a three-dimensional (3D) scan of an object includes applying an optical contrast powder to the object and illuminating the object with light. First and second two-dimensional (2D) color image data corresponding to the object is generated. First and second 2D monochrome image data corresponding to the object is generated using the first and second 2D color image data. 3D data corresponding to the object is generated using the first and second monochrome 2D image data. Color 3D image data corresponding to the object is generated by adding color information to the 3D data. The color 3D image data is displayed.
