Abstract

Claims (28)

1. A position determination system, comprising:

a two-dimensional code arrangement;

a sensor unit; and

an evaluation unit;

wherein:

the sensor unit is configured to capture an image of the two-dimensional code arrangement;

the evaluation unit is configured to process the image of the two-dimensional code arrangement; and

the processing of the image of the two-dimensional code arrangement includes:

identifying a first region of the two-dimensional code arrangement as being a first predefined area dedicated to a first data category and identifying a second region of the two-dimensional code arrangement as being a second predefined area dedicated to a second data category, each of the first and second predefined areas including basic symbols arranged on a surface; and

based on the identification:

decoding the basic symbols arranged in the first predefined area to identify a position of a component with respect to each of six degrees of freedom in a space outside of the two-dimensional code arrangement; and

decoding the basic symbols arranged in the second predefined area to identify data other than a positional orientation of the component in the six degrees of freedom.

2. The position determination system according to claim 1 , wherein, with the decoding of the basic symbols arranged in the second predefined area, the evaluation unit identifies an item of application information, and/or identification information, and/or device information, and/or function information.

3. The position determination system according to claim 1 , wherein, with the decoding of the basic symbols arranged in the second predefined area, the evaluation unit identifies size information, and/or scaling information, and/or calibration information, and/or scale information.

4. The position determination system according to claim 1 , wherein, with the decoding of the basic symbols arranged in the second predefined area, the evaluation unit identifies a release status and/or an item of security information and/or database information and/or address information and/or link information and/or authenticity information item and/or key information.

5. The position determination system according to claim 1 , wherein the evaluation unit is configured to process the two-dimensional code arrangement in order to identify a position and/or location and/or orientation of each of one or more of the predefined areas in the two-dimensional code arrangement.

6. The position determination system according to claim 1 , wherein the basic symbols arranged in the first predefined area differ from the basic symbols arranged in the second predefined area with respect to shape.

7. The position determination system according to claim 1 , wherein the basic symbols arranged in the first predefined area differ from the basic symbols arranged in the second predefined area with respect to color.

8. The position determination system according to claim 1 , wherein the arranged basic symbols include and/or form a QR code and/or a dot code and/or a barcode and/or ArUco code.

9. The position determination system according to claim 1 , wherein the two-dimensional code arrangement includes a third predefined area that includes at least one symbol that specifies a reading order and/or encoding order of the basic symbols in the first and/or second predefined areas, the first predefined area including an X defined region and a Y defined region, the evaluation unit being configured to identify an X coordinate value using the basic symbols in the X defined region and to identify a Y coordinate value using the basic symbols in the Y defined region.

10. The position determination system according to claim 1 , wherein the basic symbols arranged on the surface form a two-dimensional periodic grid.

11. A method for component position identification using a two-dimensional code arrangement, a sensor unit, and an evaluation unit, the method comprising:

capturing, with the sensor unit, an image of the two-dimensional code arrangement; and

processing, by the evaluation unit, the image of the two-dimensional code arrangement, wherein the processing of the image of the two-dimensional code arrangement includes:

identifying a first region of the two-dimensional code arrangement as being a first predefined area dedicated to a first data category and identifying a second region of the two-dimensional code arrangement as being a second predefined area dedicated to a second data category, each of the first and second predefined areas including basic symbols arranged on a surface; and

based on the identification:

decoding the basic symbols arranged in the first predefined area to identify a position of a component with respect to each of six degrees of freedom; and

decoding the basic symbols arranged in the second predefined area to identify data other than a positional orientation of the component in the six degrees of freedom.
