Abstract

An example hologram device may include a target holographic view of an encoded holographic image representing an alignment target; and a plurality of non-target holographic views of the encoded holographic image, each non-target holographic view indicating a position relative to the target holographic view.

First claim

What is claimed is:

1. A hologram device, comprising:
a target holographic view of an encoded holographic image representing an alignment target; and
a plurality of non-target holographic views of the encoded holographic image, each non-target holographic view indicating a position relative to the target holographic view.

2. The device of claim 1 , wherein the encoded holographic image includes a three-dimensional object.

3. The device of claim 2 , wherein the three-dimensional object includes an asymmetric feature to facilitate rotational alignment.

4. The device of claim 1 , wherein each non-target holographic view of the encoded holographic image includes a code associated with the position relative to the target holographic view.

5. The device of claim 4 , wherein the code is a machine-readable code.

6. The device of claim 4 , wherein the code is associated with the position relative to the target holographic view through a table look-up.

7. The device of claim 1 , wherein each non-target holographic view of the encoded holographic image includes a first angle indicative of an elevation angle and a second angle indicative of an azimuth value.

8. The device of claim 1 , wherein each non-target holographic view of the encoded holographic image includes a graphical representation indicative of the position relative to the target holographic view.

9. A method, comprising:
detecting a non-target holographic view of an encoded holographic image on a hologram device, the non-target holographic view indicating a position relative to a target holographic view of the encoded holographic image;
causing a change in the position relative to the target holographic view based on the non-target holographic view indicating the position relative to the target holographic view.

10. The method of claim 9 , wherein the encoded holographic image includes an image of a three-dimensional object.

11. The method of claim 10 , wherein the three-dimensional object includes an asymmetric feature indicating a rotational orientation of the hologram device, and wherein the method further comprises:
causing a rotation to change the rotational orientation of the hologram device based on the indication of the orientation by the asymmetric feature of the three-dimensional object.

12. The method of claim 9 , wherein the non-target holographic view of the encoded holographic image includes a machine-readable code associated with the position relative to the target holographic view.

13. A system, comprising:
a hologram device associated with an object, the hologram device including a plurality of non-target holographic views of an encoded holographic image, each non-target holographic view including a machine-readable code indicating a position relative to a target holographic view;
an imaging device to read the machine-readable code of at least one of the non-target holographic views; and
a processor for determining an alignment position of the object relative to the imaging device based on the machine readable code encoded on the at least one of the non-target holographic views.

14. The system of claim 13 , wherein the hologram device further includes a target holographic view of the encoded holographic image, the target holographic view representing an alignment target.

15. The system of claim 13 , wherein the machine readable code is a bar code, a quick-read (QR) code, or a two-dimensional bar code.
