Abstract

An apparatus and method for determining a characteristic of a selected skin lesion. A capture device produces data representing an image of an object. A processing device processes the data to derive a three-dimensional model of the skin lesion, which is stored in a database. A reporting device indicates at least one specific property of the selected skin lesion. The processing device determines a change in at least one specific property of the skin lesion by comparing the three-dimensional model with at least one previously derived three-dimensional model that is stored in the database.

Claims

1. An apparatus for at least one of measuring and characterizing a selected skin lesion, comprising:

a capture device that produces data representing an image of an object;

a processing device that processes said data to derive a three-dimensional model of the skin lesion that is stored in a database; and

a reporting device that indicates at least one specific property of the selected skin lesion, wherein said processing device determines a change in said at least one specific property by comparing said three-dimensional model with at least one previously derived three-dimensional model stored in said database, wherein said data representing an image includes information related to at least one of color and texture of the object.

2. The apparatus of claim 1, wherein said capture device comprises an electronic stereoscopic camera.

3. The apparatus of claim 1, wherein said capture device comprises an electronic camera having at least one periscope.

4. The apparatus of claim 3, wherein said electronic camera captures at least two images on a split frame.

5. The apparatus of claim 1, wherein said capture device captures space diverse views of the object.

6. The apparatus of claim 1, wherein said capture device comprises a scanner.

7. The apparatus of claim 1, wherein said capture device comprises plural cameras.

8. The apparatus of claim 1, wherein said capture device further comprises a memory that stores said captured image.

9. The apparatus of claim 8, wherein said stored captured image is analyzed by said processing device at a time that is substantially later from when the image was captured.

10. The apparatus of claim 1, further comprising an interface that selectively connects said capture device to said processing device.

11. The apparatus of claim 1, wherein said reporting device comprises a display.

12. The apparatus of claim 1, wherein said data stored in said database is correlated with selected information.

13. The apparatus of claim 12, wherein said selected information comprises at least one of patient identification, lesion location, date said data representing said image of said object was produced, time said data representing said image of said object was produced, and identification of personnel treating said object.

14. The apparatus of claim 1, further comprising a pattern generator that projects a predetermined pattern onto said object.

15. The apparatus of claim 14, wherein said predetermined pattern comprises a grid pattern.

16. The apparatus of claim 14, wherein said predetermined pattern comprises a plurality of geometric shapes.

17. A method for at least one of measuring and characterizing a selected skin lesion, comprising:

producing data that represents an image of an object;

processing the data to derive a three-dimensional model of the skin lesion that is stored in a database; and

indicating at least one specific property of the selected skin lesion, wherein a change in the at least one specific property is determined by comparing the three-dimensional model with at least one previously derived three-dimensional model stored in the database, wherein the data representing an image includes information related to at least one of color and texture of the object.

18. The method of claim 17, further comprising using an electronic stereoscopic camera to capture the image.

19. The method of claim 17, further comprising using an electronic camera having at least one periscope to capture the image.

20. The method of claim 19, further comprising capturing at least two images on a split frame of the electronic camera.

21. The method of claim 17, further comprising using a capture device that captures space diverse views of the object.

22. The method of claim 21, wherein the capture device further comprises storing the captured image in a memory.

23. The method of claim 22, further comprising processing the captured image stored in the memory at a time that is substantially later from when the image was captured.

24. The method of claim 17, wherein producing data that represents an image of an object comprises using a scanner.

25. The method of claim 17, further comprising using plural cameras to capture the image.

26. A method for at least one of measuring and characterizing features of an object, comprising:

transforming an initial image view to a two-dimensional physical perspective representation of an image corresponding to the object;

identifying unique features of the two-dimensional perspective representation of the image;

correlating the identified unique features to produce a three-dimensional physical representation of all uniquely-identified features; and

determining three-dimensional characteristic features of the object, wherein the identified unique features include information related to at least one of color, and texture of the object.

27. The method of claim 26, further comprising using a capture device that produces the initial image view by capturing space diverse views of the object.

28. The method of claim 26, wherein the capture device further comprising storing the initial image view in a memory, associated with the capture device, for later retrieval.

29. An apparatus for at least one of measuring and characterizing features of an object, comprising:

an imaging device that captures a two-dimensional image of the object;

a processing device that processes said captured image to produce a three-dimensional representation of the object, said three-dimensional representation including parameters indicating a predetermined feature of the object;

a database that stores said parameters;

a comparing device that compares said stored parameters to previously stored parameters related to the object to determine a change in the three-dimensional representation of the object; and

a reporting device that uses results of said comparison by said comparing device to generate a report pertaining to a change in the object, wherein said parameters indicating a predetermined feature of the object includes information related to at least one of color and texture of the object.

30. The apparatus of claim 29, further comprising a pattern generator that projects a predetermined pattern onto the object to assist in capturing said two-dimensional image of the object.

31. The apparatus of claim 29, further comprising an interface that selectively connects said imaging device to said processing device.
