Matrix barcode having a plurality of colors and an infrared layer for conveying spatial information
A matrix barcode on a surface may comprise a plurality of colors and an infrared layer. The matrix barcode may be a fiducial marker for conveying spatial information. The conveyed spatial information may stem at least in part from the infrared layer.
1. An article of manufacture comprising:
a matrix barcode on a surface, wherein the matrix barcode comprises a plurality of colors and an infrared layer, wherein the matrix barcode is a fiducial marker for conveying spatial information, and wherein the conveyed spatial information stems at least in part from the infrared layer.
2. The article of manufacture of claim 1 , wherein the surface is configured to reflect infrared light, and wherein the infrared layer reflects infrared light.
3. The article of manufacture of claim 2 , wherein the surface is a computer display that displays the matrix barcode.
4. The article of manufacture of claim 3 , wherein the plurality of colors are associated with at least three color channels, wherein the matrix barcode is embedded with computer data, wherein the computer data is represented by a plurality of pixels associated with the at least three color channels, and an infrared channel associated with the infrared layer.
5. The article of manufacture of claim 4 , wherein the matrix barcode contains at least four bits of information.
6. The article of manufacture of claim 5 , wherein the infrared layer is a top most layer of the matrix barcode.
7. The article of manufacture of claim 6 , wherein the spatial information is to be conveyed to at least one of: i) a computer system, ii) a vehicle, and iii) an individual.
8. The article of manufacture of claim 4 , wherein each one of the plurality of colors are at least one of i) an absent color in relation to an environment containing the matrix barcode and ii) at least one least prevalent color of a plurality of prevalent colors associated with the environment.
9. The article of manufacture of claim 1 , wherein the matrix barcode is based at least in part on a conversion from a first colorspace to a second colorspace.
10. The article of manufacture of claim 1 , wherein each of the plurality of colors comprise non-black or non-white colors.
11. The article of manufacture of claim 1 , wherein the matrix barcode includes a combination of four or more constituent matrix barcodes each associated with a distinct color channel, including an infrared color channel associated with at least one layer of at least one of the four or more constituent matrix barcodes.
