Method, device and system for correlating at least one additional 2D-image to a 3D-representation of at least a part of tooth
The present disclosure provides a computer-implemented method for correlating at least one infrared 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, including the steps of: obtaining a first set of 2D-images of the at least part of the tooth; forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images; displaying, in the graphical user-interface, the 3D-representation; obtaining a second set of 2D-images, wherein the second set of 2D images are infrared 2D-images acquired within the at least part of the tooth; displaying, in the user-interface, at least one of the 2D-images from the second set of 2D-images; displaying, in the user-interface, a manipulator configured to change between 2D-images in the second set of 2D-images.
1. A computer-implemented method for correlating at least one infrared 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, comprising the steps of:
obtaining a first set of 2D-images of the at least part of the tooth;
forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images;
displaying, in the graphical user-interface, the 3D-representation;
obtaining a second set of 2D-images based with light on illuminating the tooth with light in the infrared (IR) domain;
displaying, in the user-interface, a manipulator configured to change between 2D-images in the second set of 2D-images;
based on input as associated to the manipulator, changing between the 2D-images in the second set of 2D-images until a desired 2D-image is displayed; and
correlating the desired 2D-image to the 3D-representation.
2. The method according to claim 1 , wherein the step of correlating the desired 2D-image to the 3D-representation is based on comparing information in the first set of images with information in the second set of images.
3. The method according to claim 2 , wherein the information is related to the acquisition-time of the images.
4. The method according to claim 1 , wherein the step of correlating the desired 2D-image to the 3D-representation is represented in the user-interface such that only the desired 2D-image is shown in relation to the 3D-representation of the at least a part of the tooth.
5. The method according to claim 1 , wherein the step of correlating the desired 2D-image to the 3D representation is represented in the user-interface as a combined 2D/3D-representation.
6. The method according to claim 5 , wherein the combined 2D/3D-representation comprises two separate datasets linked together by the correlation such that the combined 2D/3D-representation further comprises two separate representations.
7. The method according to claim 5 , wherein the combined 2D/3D representation comprises a single dataset obtained by correlating two separate datasets.
8. The method according to claim 1 , wherein the step of forming the 3D-representation is such that each tooth or the at least part of the tooth in the 3D-representation uniquely identifies a second set of images belonging to the respective tooth or the at least part of the tooth.
9. The method according to claim 1 , wherein the second set of 2D-images is a focus-stack of 2D-images recorded along a perpendicular axis with respect to a single 2D-physical-surface.
10. The method according to claim 1 , wherein the second set of 2D-images is a focus-stack of 2D-images recorded along a single 2D-physical surface.
11. The method according to claim 1 , wherein the manipulator displayed in the graphical user-interface is a scrollbar and/or a location-indicator to show images from selected positions and/or orientations.
12. The method according to claim 1 , wherein the manipulator displayed in the graphical user-interface is based on clicking on the 2D-image and wherein the desired image is obtained by moving a cursor, by touch input on the screen, or by using the hand-held scanning device.
13. The method according to claim 1 , wherein the step of obtaining a second set of 2D-images is based on filtering the second set of 2D images.
14. The method according to claim 1 , wherein the second set of 2D-images are obtained by, in the user-interface, selecting that the handheld scanning device is operating with one or more wavelengths in the range between 700 nm to 2500 nm.
