Abstract

Certain embodiments are directed to methods, devices, and/or systems for viewing and imaging all or most of the surface area of a three-dimensional (3-D) object with one or more two-dimensional (2-D) images.

Claims

1. An imaging system for producing a two-dimensional image of a physical object, comprising:

a reflective surface that reflects at least one portion of the electromagnetic spectrum; and

at least one camera facing the reflective surface that is capable of capturing at least one image based on reflected electromagnetic radiation;

wherein (i) the reflective surface is concave in respect to the at least one camera, comprises an apex, and is configured to reflect at least one type of electromagnetic radiation emanating from the surface of a physical object positioned along the principal axis of the reflective surface and (ii) at least one camera is positioned to capture the reflected electromagnetic radiation.

2. The imaging system of claim 1, further comprising a computer based image processor wherein the computer based image processor is configured to determine the location on the physical object that is emitting the reflected electromagnetic radiation received by the at least one camera.

3. The imaging system of claim 1, wherein the concave surface is spherical, conical, or parabolic.

4. The imaging system of claim 1, wherein the concave surface comprises more than one shape.

5. The imaging system of claim 1, wherein the concave surface comprises a conical surface portion more distant from the apex of the reflective surface and an increased reflective angle conical and/or spherical surface portion that is closer to the apex of the reflective surface.

6. The imaging system of claim 1, wherein the concave surface is configured to reflect radiation emanating from physical object along the principal axis and 360 degrees about the principle axis.

7. The imaging system of claim 1, wherein the reflective surface is capable of reflecting more than one type of electromagnetic radiation.

8. The imaging system of claim 1, wherein at least one camera has a fisheye lens.

9. The imaging system of claim 1, wherein at least one camera is capable of capturing the surface image of the object as a single image.

10. The imaging system of claim 2, wherein a computer based image processor is configured to provide a representative view of the object surface, wherein the representative view can be manipulated in virtual three dimensional space.

11. The imaging system of claim 1, wherein the system is capable of capturing the surface image of the object from two or more angles from the principle axis of the reflective surface, from two or more distances from the apex of the reflective surface, and/or using two or more focal distances.

12. The imaging system of claim 2, wherein the computer based image processor is configured to determine and/or assign a size, shape, location, or any combination thereof of a region of interest on the physical object that is emitting the reflected electromagnetic radiation based on the size, shape, location or any combination thereof of a region of interest identified in the captured image.

13. The imaging system of claim 1, wherein at least one camera is capable of capturing multiple types of electromagnetic radiation and/or the imaging system comprises at least two cameras each that are capable of capturing a different type of electromagnetic radiation than the other.

14. The imaging system of claim 1, wherein the at least one type of electromagnetic radiation is infrared light and at least one camera is a thermographic camera responsive to the infrared energy spectrum.

15. The imaging system of claim 1, wherein the concave surface reflects infrared energy.

16. The imaging system of claim 1, wherein the concave surface is aluminum.

17. The imaging system of claim 1, wherein the system is configured to produce an image that is a hotspot map of the object.

18. The imaging system of claim 1, wherein the system is configured to produce an image that is a coldspot map of the object.

19. A computer based image processor capable of mapping a location on an object based on a reflection of the object from a concave reflector captured by at least one camera.

20-35. -35. (canceled)

36. A method of identifying the location of skin irritation and/or early signs of skin irritation on a subject comprising:

placing a portion of the subject to be imaged, the subject having actively worn a prosthetic or orthotic device, along the principal axis of a reflective concave structure in view of at least one camera connected to an imaging system;

capturing at least one image of reflected infrared radiation emitted from the part of the subject being imaged with the at least one camera;

identifying any region of interest in which skin temperature is higher and/or lower than average skin temperature;

and mapping any such region of interest identified on the captured image to its corresponding actual location on the part of the subject being imaged using a computer based image processor.
