Abstract

A non-transitory computer readable medium storing data and computer implementable instructions that, when executed by at least one processor, cause the at least one processor to perform operations for generating cross section views of a wound, the operations including receiving 3D information of a wound based on information captured using an image sensor associated with an image plane substantially parallel to the wound; generating a cross section view of the wound by analyzing the 3D information; and providing data configured to cause a presentation of the generated cross section view of the wound.

First claim

What is claimed is:

1. A non-transitory computer readable medium storing data and computer implementable instructions that, when executed by at least one processor, cause the at least one processor to perform operations for generating cross section views of a wound, the operations comprising:
receiving 3D information of a wound based on information captured using an image sensor associated with an image plane substantially parallel to the wound;
selecting a cross section of the wound from a plurality of cross sections of the wound based on a boundary contour of the wound;
generating a cross section view of the wound by analyzing the 3D information, the cross section view of the wound corresponding to the selected cross section; and
providing data configured to cause a presentation of the generated cross section view of the wound.

2. The non-transitory computer readable medium of claim 1 , wherein the 3D information of the wound includes at least one of a range image, a stereoscopic image, a volumetric image, or a point cloud.

3. The non-transitory computer readable medium of claim 1 , wherein receiving the 3D information of the wound includes one or more of analyzing a video of the wound captured using the image sensor while the image sensor is moving, analyzing a video of the wound depicting a motion of the wound, or analyzing at least one image captured using the image sensor.

4. The non-transitory computer readable medium of claim 1 , wherein the 3D information of the wound includes at least one of a plurality of 2D images of the wound captured from different angles, a stereoscopic image of the wound, an image captured using an active stereo camera, or an image captured using a time-of-flight camera.

5. The non-transitory computer readable medium of claim 1 , wherein the selected cross section of the wound corresponds to a deepest point of the wound.

6. The non-transitory computer readable medium of claim 1 , wherein the selected cross section of the wound corresponds to one of a longest chord of a shape of the boundary contour or a shortest chord of the shape of the boundary contour.

7. The non-transitory computer readable medium of claim 1 , wherein the selected cross section of the wound is perpendicular to one or more of a selected chord of a shape of the boundary contour.

8. The non-transitory computer readable medium of claim 1 , wherein generating a cross section view of the wound includes:
obtaining a segmentation of the wound based on a tissue type;
selecting a cross section of the wound of a plurality of cross sections of the wound based on the segmentation of the wound; and
generating the cross section view of the wound by analyzing the 3D information, the cross section view of the wound corresponding to the selected cross section.

9. The non-transitory computer readable medium of claim 1 , wherein the generated cross section view of the wound includes one or more of tissue information for at least a portion of the wound, a visual indication of a wound depth, an estimated pre-wound skin contour, or an estimated post-wound skin contour.

10. The non-transitory computer readable medium of claim 1 , the operations further comprising:
receiving image data captured using the image sensor;
calculating a convolution of a first part of the image data to derive a first result value of the convolution of the first part of the image data;
determining a depth of the wound at a first position based on the first result value;
calculating a convolution of a second part of the image data to derive a second result value of the convolution of the second part of the image data, the second part of the image data differing from the first part of the image data; and
determining a depth of the wound at a second position based on the second result value, the second position differing from the first position.

11. The non-transitory computer readable medium of claim 1 , wherein the generated cross section view of the wound includes a plurality of parallel cross section views of the wound.

12. The non-transitory computer readable medium of claim 1 , the operations further comprising estimating at least one of an original position of a skin before a formation of the wound or a future position of the skin after healing of the wound by analyzing the 3D information, and wherein the provided data is based on at least one of the estimated original position of the skin or the future position of the skin.

13. The non-transitory computer readable medium of claim 12 , wherein the provided data includes a depth of the wound estimated based on at least one of the estimated original position of the skin or the estimated future position of the skin.

14. The non-transitory computer readable medium of claim 12 , wherein the generated cross section view of the wound includes a visual indication of at least one of the original position of the skin or the future position of the skin.

15. The non-transitory computer readable medium of claim 12 , wherein at least one of estimating the original position of the skin or estimating the future position of the skin includes implementing an inpainting algorithm based on the 3D information.

16. The non-transitory computer readable medium of claim 12 , wherein the wound corresponds to a first body part of a patient, the patient having a symmetrical body part to the first body part, and wherein at least one of estimating the original position of the skin or estimating the future position of the skin includes:
receiving 3D information of the symmetrical body part; and
analyzing the 3D information of the symmetrical body part and the 3D information of the wound.

17. A system for generating cross section views of a wound, the system comprising:
a memory storing instructions; and
at least one processor configured to execute the instructions to:
receive 3D information of a wound based on information captured using an image sensor associated with an image plane substantially parallel to the wound;
select a cross section of the wound from a plurality of cross sections of the wound based on a boundary contour of the wound;
generate a cross section view of the wound by analyzing the 3D information, the cross section view of the wound corresponding to the selected cross section; and
provide data configured to cause a presentation of the generated cross section view of the wound.

18. A computer-implemented method for generating cross section views of a wound, the method comprising:
receiving 3D information of a wound based on information captured using an image sensor associated with an image plane substantially parallel to the wound;
selecting a cross section of the wound from a plurality of cross sections of the wound based on a boundary contour of the wound;
generating a cross section view of the wound by analyzing the 3D information, the cross section view of the wound corresponding to the selected cross section; and
providing data configured to cause a presentation of the generated cross section view of the wound.
