Abstract

A system and a method for transforming graphical images. Graphical images are adapted by the present invention to be applied to a three-dimensional topography of a substrate. After the image is applied to the substrate, the image then appears in proportion and conforms to the (topography of the substrate. In an embodiment, the present invention comprises a method for creating at least one transformed graphical image. The topography of a substrate is measured by using a digitizing apparatus to obtain at least one image of the topography of a measurement article. The digitizing apparatus comprises at least one sensor that is electronically interconnected with a computer memory. The at least one image of the measurement article is transmitted into the computer memory. A graphical image is transformed in computer memory in accordance with the measurements of the topography of the measurement article to result in a transformed graphical image.

Claims

1. A method for creating a transformed graphical image, the method comprising the steps of:

providing a measurement article having a three-dimensional topography, said measurement article comprising a plurality of measurement points, wherein said plurality of measurement points collectively are suggestive of at least part of said topography of said measurement article;

obtaining at least one electronic representation of said at least one of said plurality of measurement points with a digitizing apparatus, said digitizing apparatus comprising at least one sensor electronically interconnected with a computer memory, said digitizing apparatus adapted to relocate said at least one sensor, and said measurement article in relation to each other, wherein said electronic representation is obtained in a manner not involving contact between said at least one sensor and said measurement article;

transforming, in said computer memory, at least one graphical image into at least one transformed graphical image using said topography of said measurement article;

applying said at least one transformed graphical image onto a substrate; and

producing a three-dimensional part from said substrate, wherein the an appearance of said at least one transformed graphical image on said substrate is altered such that said at least one transformed graphical image takes on an appearance that more closely resembles said graphical image, wherein said alteration only includes deformation of said substrate.

2. The method of claim 1, wherein the step of obtaining at least one electronic representation comprises the steps of:

obtaining two or more separate electronic representations with said at least one sensor, each said separate electronic representation comprising at least one of said plurality of measurement points; and

combining said two or more separate electronic representations in said computer memory.

3. The method of claim 1, wherein said at least one sensor comprises at least one optical sensor.

4. The method of claim 1, further comprising, before the step of obtaining at least one electronic representation, the step of:

relocating said at least one sensor and said measurement article in relation to each other so that at least one of said at least one sensor is positioned to obtain at least one electronic representation of said at least one of said plurality of measurement points, said at least one sensor being adapted to obtain said at least one electronic representation from said changed relative position without the need for recalibration of said digitizing apparatus.

5. The method of claim 1, wherein said at least one sensor is not able to obtain at least one electronic representation of all of said plurality of measurement points simultaneously, the method further comprising the steps of:

(a) relocating said at least one sensor and said measurement article in relation to each other so that at least one of said at least one sensor is positioned to obtain at least one electronic representation of said at least one of said plurality of measurement points, said at least one sensor being adapted to obtain said at least one electronic representation from said changed relative position without the need for recalibration of said digitizing apparatus;

(b) obtaining said at least one electronic representation of at least one of said plurality of measurement points with said at least one sensor; and

(c) repeating steps (a) and (b) until at least one electronic representation of each of said plurality of measurement points is stored in said computer memory.

6. The method of claim 1, wherein the step of transforming at least one graphical image into at least one transformed graphical image comprises the steps of:

creating a three-dimensional grid in said computer memory, said three-dimensional grid being reflective of said topography of said measurement article;

combining, in said computer memory, said three-dimensional grid and said at least one graphical image; and

converting, in said computer memory, said three-dimensional grid into a two-dimensional grid.

7. The method of claim 6, wherein each of said at least one graphical images comprises at least one texture map, and wherein the step of combining said three-dimensional grid and said at least one graphical image comprises the steps of:

aligning said three-dimensional grid and at least one of said at least one texture maps in said computer memory; and

applying said at least one of said at least one texture maps to said three-dimensional grid in said computer memory.

8. The method of claim 7, wherein the step of aligning said three-dimensional grid and at least one of said at least one texture maps comprises the steps of:

selecting at least one registration point on said three-dimensional grid; and

selecting at least one registration point on at least one of said at least one texture maps, said at least one registration point on at least one of said at least one texture maps corresponding to said at least one registration point on said three-dimensional grid.

9. The method of claim 6, wherein said three-dimensional grid comprises a plurality of three-dimensional grid points, and wherein the step of converting said three-dimensional grid into a two-dimensional grid comprises the steps of:

providing planar grid data in said computer memory, said planar grid data comprising a plurality of planar grid points, said planar grid points being at least equal in number to said plurality of three-dimensional grid points in said three-dimensional grid;

corresponding, in said computer memory, said three-dimensional grid points and said planar grid points; and

causing said three-dimensional grid to take on a two-dimensional appearance by translating, in computer memory, each of said three-dimensional grid points into its corresponding said planar grid point.

10. The method of claim 1, wherein the step of applying said at least one transformed graphical image onto said substrate comprises the step of:

projecting said at least one transformed graphical image onto said substrate.
