Abstract

Claims (51)

1 . A method for providing depth perception to a two-dimensional (2D) representation of a given three-dimensional (3D) object within a 2D non-visible spectrum image of a scene, the method comprising:

capturing the 2D non-visible spectrum image at a capture time, by at least one non-visible spectrum sensor;

obtaining 3D data regarding the given 3D object independently of the 2D non-visible spectrum image;

generating one or more depth cues based on the 3D data;

applying the depth cues on the 2D representation to generate a depth perception image that provides the depth perception to the 2D representation; and

displaying the depth perception image.

2 . The method of claim 1 , wherein the 3D data is a priori data regarding coordinates of a fixed coordinate system established in space that are associated with the given 3D object, the a priori data being available prior to the capture time; and

wherein the depth cues are generated based on the a priori data and an actual position and orientation of the non-visible spectrum sensor relative to the fixed coordinate system at the capture time.

3 . The method of claim 1 , wherein the 3D data is one or more readings by an additional sensor that is distinct from the non-visible spectrum sensor; and

wherein the depth cues are generated based on the readings and a first actual position and orientation of the non-visible spectrum sensor at the capture time relative to a second actual position and orientation of the additional sensor at a second time of the readings.

4 . The method of claim 1 , further comprising:

recording the 2D non-visible spectrum image to provide a recording of the 2D non-visible spectrum image;

wherein the depth cues are applied on the 2D representation within the 2D non-visible spectrum image as recorded.

5 . The method of claim 1 , wherein the depth cues include one or more of the following:

(a) one or more shadows;

(b) a virtual object; or

(c) contour lines.

6 . The method of claim 5 , wherein at least some of the shadows are generated by one or more virtual light sources.

7 . The method of claim 6 , further comprising:

selecting one or more selected light sources of the virtual light sources.

8 . The method of claim 7 , wherein, for at least one selected light source of the selected light sources, one or more parameters of the at least one selected light source are defined by a user, the one or more parameters including a position and an orientation of the at least one selected light source.

9 . The method of claim 5 , wherein the virtual object is distinguishable from the 2D representation.

10 . A system for providing depth perception to a two-dimensional (2D) representation of a given three-dimensional (3D) object within a 2D non-visible spectrum image of a scene, the system comprising:

at least one non-visible spectrum sensor configured to capture the 2D non-visible spectrum image at a capture time; and

a processing circuitry configured to:

obtain 3D data regarding the given 3D object independently of the 2D non-visible spectrum image;

generate one or more depth cues based on the 3D data;

apply the depth cues on the 2D representation to generate a depth perception image that provides the depth perception to the 2D representation; and

display the depth perception image.

11 . The system of claim 10 , wherein the 3D data is a priori data regarding coordinates of a fixed coordinate system established in space that are associated with the given 3D object, the a priori data being available prior to the capture time; and

wherein the depth cues are applied based on the a priori data and an actual position and orientation of the non-visible spectrum sensor relative to the fixed coordinate system at the capture time.

12 . The system of claim 10 , wherein the 3D data is one or more readings by an additional sensor that is distinct from the non-visible spectrum sensor; and

wherein the depth cues are generated based on the readings and a first actual position and orientation of the non-visible spectrum sensor at the capture time relative to a second actual position and orientation of the additional sensor at a second time of the readings.

13 . The system of claim 10 , wherein the processing circuitry is further configured to:

record the 2D non-visible spectrum image to provide a recording of the 2D non-visible spectrum image;

wherein the depth cues are applied on the 2D non-visible spectrum image as recorded.

14 . The system of claim 10 , wherein the depth cues include one or more of the following:

(a) one or more shadows;

(b) a virtual object; or

(c) contour lines.

15 . The system of claim 14 , wherein at least some of the shadows are generated by one or more virtual light sources.

16 . The system of claim 15 , wherein the processing circuitry is further configured to:

select one or more selected light sources of the virtual light sources.

17 . The system of claim 16 , wherein, for at least one selected light source of the selected light sources, one or more parameters of the at least one selected light source are defined by a user of the system, the one or more parameters including a position and an orientation of the at least one selected light source.

18 . The system of claim 14 , wherein the virtual object is distinguishable from the 2D representation.

19 . A non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code, executable by processing circuitry of a computer to perform a method for providing depth perception to a two-dimensional (2D) representation of a given three-dimensional (3D) object within a 2D non-visible spectrum image of a scene, the method comprising:

capturing the 2D non-visible spectrum image at a capture time, by at least one non-visible spectrum sensor;

obtaining 3D data regarding the given 3D object independently of the 2D non-visible spectrum image;

generating one or more depth cues based on the 3D data;

applying the depth cues on the 2D representation to generate a depth perception image that provides the depth perception to the 2D representation; and

displaying the depth perception image.
