Abstract
In accordance with a first aspect of the present disclosure, a method for providing a code pattern which is readable by a sensor is conceived, the method comprising: defining a plurality of coding positions as a subset of positions in a two-dimensional matrix; including in said subset a plurality of positions which are diagonally adjacent to each other; selectively creating coding marks, such as coding dots, at the coding positions. In accordance with a second aspect of the present disclosure, a corresponding code pattern is provided.

A method for providing a code pattern which is readable by a sensor, comprising:
- defining a plurality of coding positions as a subset of positions in a two-dimensional matrix;
- including in said subset a plurality of coding positions which are diagonally adjacent to each other and a plurality of coding positions that are not adjacent to other coding positions;
- removing one coding position of a pair of coding positions in the subset that are vertically adjacent to each other;
- removing one coding position of a pair of coding positions in the subset that are horizontally adjacent to each other;
- and
- selectively creating coding marks only at the diagonally adjacent coding positions and at the coding positions that are not adjacent vertically or horizontally to other coding positions.
A code pattern which is readable by a sensor, the code pattern comprising:
- selectively created coding marks at a plurality of coding positions;
- wherein the plurality of coding positions is defined as a subset of positions in a two-dimensional matrix;
- and wherein said subset of positions only includes a plurality of coding positions which are diagonally adjacent to each other and a plurality of coding positions that are not adjacent to other coding positions either vertically or horizontally.
