Abstract

A method for detecting and displaying image data of at least one object with reference to a human or animal body is provided with the following method steps: detecting a spatial structure and position of the object through a physical space detection and generating image data of the object on the basis of this detection, projecting the image data onto an artificial body, which represents the human or animal body, and displaying the object using the image data projected onto the artificial body.

Claims

1. A method for detecting and displaying image data of at least one object with reference to a human or animal body comprising:

detecting a spatial structure and/or position of the object through a physical space detection, and generating image data of the object on the basis of this detection,

projecting the image data onto an artificial body which represents the human or animal body, and

displaying the object using the image data projected onto the artificial body.

2. The method according to claim 1,

wherein the artificial body is an avatar with a form representing the human or animal body in an abstract manner.

3. The method according to claim 2,

wherein, from the avatar with the object projected on it, a simplified wind-off surface is displayed.

4. The method according to claim 3,

wherein the simplified wind-off surface is a pattern for a virtual clothing and/or that the simplified wind-off surface is segmented into partial regions which correspond to the different regions of the body.

5. The method according to claim 1,

wherein either the object itself or the position of the object on the artificial body is displayed with an image display device.

6. The method according to claim 1,

wherein the position of the object on the human or animal body is displayed especially through a directed light emission, especially through a laser pointer.

7. The method according to claim 1,

wherein the image data projected onto the artificial body are re-projected and displayed on an optical image of the human or animal body.

8. The method according to claim 7,

wherein, in the projection, a transformation is used and in the re-projection, a re-transformation is used which are mutually bijective.

9. The method according to claim 8,

wherein, in the transformation an encryption is used without a knowledge of which the re-transformation is rendered impossible or at least difficult.

10. The method according to claim 1,

wherein for the physical space detection, a microwave scanner using microwave radiation and/or an x-ray scanner using x-ray radiation is used.

11. The method according to claim 1,

wherein the image data are revised through a noise suppression and/or a suppression of low-frequency signal components which are caused by the contour of the human or animal body, and/or through a cartoon-like presentation of outlines and/or flat structures, especially filled contours.

12. A device for detecting and displaying image data of at least one object with reference to a human or animal body, said device comprising:

a detection device for detecting a spatial structure and/or position of the object by a physical space detection and for generating image data of the object on the basis of this detection,

a projection processor for projecting the image data onto an artificial body, which represents the human or animal body,

and a display device for displaying the object using the image data projected onto the artificial body.

13. The device according to claim 12,

wherein the artificial body is an avatar with a form representing the human or animal body in an abstract manner.

14. The device according to claim 13,

wherein a wind-off-surface processor, which generates a simplified wind-off surface from the avatar with object projected on it.

15. The device according to claim 14,

wherein the wind-off-surface processor is formed in such a manner that the simplified wind-off surface provides the pattern of a virtual clothing and/or that the simplified wind-off surface is segmented into partial regions which correspond to the different regions of the body.

16. The device according to claim 12,

wherein the display device provides an image display device, which displays either the object itself or the position of the object on the artificial body.

17. The device according to claim 12,

wherein the display device comprises a body-display device, especially a laser pointer, which displays the position of the object directly on the human or animal body, especially through a directed light emission, especially through a laser beam.

18. The device according to claim 12,

wherein a re-projection processor, which re-projects the image data projected onto the artificial body, wherein the display device displays the re-projected image data on an optical image of the human or animal body detected by a camera.

19. The device according to claim 18,

wherein, in the projection, the projection processor uses a transformation, and in the re-projection, the re-projection processor uses a re-transformation which are mutually bijective.

20. The device according to claim 19,

wherein, in the projection, the projection processor uses an encryption without a knowledge of which the re-transformation is rendered impossible or at least difficult.

21. The device according to claim 12,

wherein the detection device provides a microwave scanner using microwave radiation or an x-ray scanner using x-ray radiation.

22. The device according to claim 12,

wherein a noise suppression processor which subjects the image data to a noise suppression and/or a filter device for the suppression of the low-frequency signal components in the image data which are caused by the contour of the human or animal body, and/or an image abstraction processor for revising the image data to provide a cartoon-like display of outlines and/or flat structures, especially filled contours.
