Abstract

An apparatus for angle-based localization of a position on a surface of an object includes an orientation sensor configured to be arranged in a known relationship relative to a position, to be identified, on a surface of an object at at least one measurement time and to capture angle information items in respect of the current orientation thereof at the measurement time, and a programmable device, with a processor and a memory, wherein the memory contains instructions and at least one assignment prescription for the object with the surface, where angle information items are assigned associated positions on the surface of the object, and wherein the instructions cause the programmable device to receive the angle information items captured at the measurement time by the orientation sensor and to establish the position to be identified by an assignment to the captured angle information items on the basis of the assignment prescription.

First claim

The invention claimed is:

1. An apparatus for angle-based localization of a position on a surface of an object, comprising:
an orientation sensor arranged in a known relationship relative to a position to be identified on a surface of an object at a measurement time and to capture angle information relating to its current orientation at the measurement time;
a programmable device including a processor and a memory, wherein the memory has instructions that, when executed by the processor, cause the programmable device to receive the angle information captured by the orientation sensor at the measurement time and to determine the position to be identified by means of assignment of the captured angle information on the basis of the assignment rule;
a camera sensor; and
a user interface, wherein angle information from historical images of the position on the surface of the object are displayed using the user interface for comparison to the current orientation of the orientation sensor.

2. The apparatus as claimed in claim 1 , wherein the orientation sensor is in direct physical contact with the surface of the object at the measurement time.

3. The apparatus as claimed in claim 1 , wherein the orientation sensor is configured to contactlessly assume a predefined local relationship with respect to the surface of the object.

4. The apparatus as claimed in claim 1 , further comprising:
a holding device which makes it possible to at least arrange the orientation sensor in the known relationship relative to the position to be identified on the surface of the object.

5. The apparatus as claimed in claim 4 , wherein the holding device comprises the orientation sensor.

6. The apparatus as claimed in claim 5 , wherein the holding device has a communication interface which is used to transmit the captured angle information to the programmable device.

7. The apparatus as claimed in claim 6 , wherein the communication interface is an interface for wireless communication.

8. The apparatus as claimed in claim 1 , wherein the orientation sensor and the programmable device are accommodated in a common housing.

9. The apparatus as claimed in claim 8 , wherein the orientation sensor and the programmable device are components of a mobile electronic unit or a mobile telephone.

10. The apparatus as claimed in claim 1 ,
wherein the instructions, when executed by the processor, also cause the programmable device to be configured to store at least one digital image recorded by the camera sensor in association with the angle information captured at the measurement time.

11. The apparatus as claimed in claim 10 , wherein the at least one digital image is stored with the angle information captured at the measurement time as metadata in a common file.

12. The apparatus as claimed in claim 10 , wherein the camera sensor and the orientation sensor have a fixed position with respect to one another, and the orientation sensor is configured to capture associated angle information relating to its current orientation when recording the at least one digital image with the camera sensor, and the instructions, when executed by the processor, also cause the programmable device to be configured to store the associated angle information captured when recording the at least one digital image in association with the at least one digital image.

13. A non-transitory computer readable media for use with an apparatus for angle-based localization of a position on a surface of an object as claimed in claim 1 , wherein the apparatus has an orientation sensor for capturing angle information relating to its current orientation and a programmable device with a processor and a memory operable to assign associated positions on the surface of the object to angle information, and wherein the computer readable media comprises:
instructions stored thereon which, when executed by the processor, at least cause the programmable device to receive the angle information captured by the orientation sensor at the measurement time and to determine the position to be identified by means of assignment of the captured angle information to the object.

14. A method for angle-based localization of a position on a surface of an object, comprising:
arranging an orientation sensor, which is configured to capture angle information relating to the current orientation of the orientation sensor at a measurement time, in a known relationship relative to a position to be identified on a surface of an object at the measurement time;
providing angle information associated with one or more historical images stored for the position to be identified on the surface of the object for comparison,
capturing the angle information at the measurement time; and
determining the position to be identified by means of assignment of the captured angle information to the object.

15. The method as claimed in claim 14 , wherein the arranging comprises bringing the orientation sensor into physical contact with the surface of the object at the measurement time.

16. The method as claimed in claim 14 , wherein the arranging comprises contactlessly arranging the orientation sensor in such a manner that it assumes a predefined local relationship with respect to the surface of the object.

17. The method as claimed in claim 14 , further comprising:
recording at least one digital image with respect to the position to be identified using a camera sensor; and
storing the at least one digital image in association with the angle information captured at the measurement time.

18. The method as claimed in claim 17 , further comprising, if the camera sensor and the orientation sensor have a fixed position with respect to one another, when recording the at least one digital image using the camera sensor, using the orientation sensor to capture associated angle information relating to its current orientation; and
storing the associated angle information captured when recording the at least one digital image in association with the at least one digital image.

19. The method as claimed in claim 14 , wherein the providing comprises displaying the angle information associated with the one or more stored historical images to a user via a user interface in comparison with angle information relating to the current orientation.
