Abstract

Systems, methods, apparatus, and computer program products are provided for displaying three-dimensional image data. For example, the position of one or more markers can be tracked. Then, image may be displayed based at least in part on the position of the one or more markers.

Claims

1. A method for displaying three-dimensional image data, the method comprising:

determining a distance between one or more markers and a tracking device, wherein the distance is determined based at least in part on position data associated with the one or more markers;

determining coordinates of the one or more markers in world space based at least in part on the position data associated with the one or more markers;

determining at least one rotation angle of the one or more markers in world space based at least in part on the position data associated with the one or more markers; and

causing display of three-dimensional image data based at least in part on (a) the distance between the one or more markers and the tracking device, (b) the coordinates of the one or more markers in world space, and (c) the at least one rotation angle of the one or more markers in world space.

2. The method of claim 1 further comprising receiving the position data associated with the one or more markers read by the tracking device, wherein (a) the one or more markers reflect light and (b) the tracking device reads the light reflected by the one or more markers.

3. The method of claim 1 further comprising receiving the position data associated with the one or more markers read by the tracking device, wherein (a) the one or more markers emit light and (b) the tracking device reads the light emitted by the one or more markers.

4. The method of claim 1 further comprising determining a scaling based at least in part on the position data associated with the one or more markers, wherein causing display of the three-dimensional image data is further based at least in part on the scaling.

5. The method of claim 1, wherein the coordinates of the one or more markers in world space comprise an x-coordinate and a y-coordinate.

6. The method of claim 1, wherein the at least one rotation angle of the one or more markers in the world space is selected from the group consisting of an x-rotation angle, a y-rotation angle, and a z-rotation angle.

7. The method of claim 1, wherein (a) the distance between the one or more markers and the tracking device, (b) the coordinates of the one or more markers in world space, and (c) the at least one rotation angle of the one or more markers in world space are determined for each frame of the three-dimensional image data displayed.

8. A computer program product for displaying three-dimensional image data, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

an executable portion configured to determine a distance between one or more markers and a tracking device, wherein the distance is determined based at least in part on position data associated with the one or more markers;

an executable portion configured to determine coordinates of the one or more markers in world space based at least in part on the position data associated with the one or more markers;

an executable portion configured to determine at least one rotation angle of the one or more markers in world space based at least in part on the position data associated with the one or more markers; and

an executable portion configured to cause display of three-dimensional image data based at least in part on (a) the distance between the one or more markers and the tracking device, (b) the coordinates of the one or more markers in world space, and (c) the at least one rotation angle of the one or more markers in world space.

9. The computer program product of claim 8 further comprising an executable portion configured to receive the position data associated with the one or more markers read by the tracking device, wherein (a) the one or more markers reflect light and (b) the tracking device reads the light reflected by the one or more markers.

10. The computer program product of claim 8 further comprising an executable portion configured to receive the position data associated with the one or more markers read by the tracking device, wherein (a) the one or more markers emit light and (b) the tracking device reads the light emitted by the one or more markers.

11. The computer program product of claim 8 further comprising an executable portion configured to determine a scaling based at least in part on the position data associated with the one or more markers, wherein causing display of the three-dimensional image data is further based at least in part on the scaling.

12. The computer program product of claim 8, wherein the coordinates of the one or more markers in world space comprise an x-coordinate and a y-coordinate.

13. The computer program product of claim 8, wherein the at least one rotation angle of the one or more markers in the world space is selected from the group consisting of an x-rotation angle, a y-rotation angle, and a z-rotation angle.

14. The computer program product of claim 8, wherein (a) the distance between the one or more markers and the tracking device, (b) the coordinates of the one or more markers in world space, and (c) the at least one rotation angle of the one or more markers in world space are determined for each frame of the three-dimensional image data displayed.

15. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

determine a distance between one or more markers and a tracking device, wherein the distance is determined based at least in part on position data associated with the one or more markers;

determine coordinates of the one or more markers in world space based at least in part on the position data associated with the one or more markers;

determine at least one rotation angle of the one or more markers in world space based at least in part on the position data associated with the one or more markers; and

cause display of three-dimensional image data based at least in part on (a) the distance between the one or more markers and the tracking device, (b) the coordinates of the one or more markers in world space, and (c) the at least one rotation angle of the one or more markers in world space.

16. The apparatus of claim 15, wherein the memory and computer program code are further configured to, with the processor, cause the apparatus to receive the position data associated with the one or more markers read by the tracking device, wherein (a) the one or more markers reflect light and (b) the tracking device reads the light reflected by the one or more markers.

17.
