Abstract
A pattern includes a spatial configuration of color codes. Each color code is a unique configuration of colors selected from a number of basis colors. The color codes each include the same number of colors.
Claims15
A method comprising:
- generating, by a processor, a pattern comprising a spatial configuration of a plurality of color codes, each color code including a unique configuration of colors selected from a number of basis colors, the color codes each including a same number of colors;
- and,
- outputting the pattern, by the processor.
A non-transitory computer-readable data storage medium storing a computer program for execution by a processor to perform a method comprising:
- determining a correspondence mapping between spatial coordinates of a pattern as detected within an image captured by a camera and reference spatial coordinates of the pattern as known beforehand,
- wherein the pattern comprising a spatial configuration of a plurality of color codes, each color code including a unique configuration of colors selected from a number of basis colors, the color codes each including a same number of colors.
A system comprising:
- a processor;
- a computer-readable data storage medium to store a computer program executable by the processor;
- and,
- a pattern detection component implemented by the computer program to detect a pattern within an image captured by a camera, the pattern comprising a spatial configuration of a plurality of color codes, each color code including a unique configuration of colors selected from a number of basis colors, the color codes each including a same number of colors,
- where the pattern encodes both geometric information and color information.
