Method and device for displaying a two-dimensional image of a viewed object simultaneously with an image depicting the three-dimensional geometry of the viewed object
A method, device, and computer readable medium for displaying a two-dimensional image of a viewed object simultaneously with an image depicting a three-dimensional geometry of the viewed object using a video inspection device is disclosed. The video inspection device displays a two-dimensional image of the object surface of a viewed object, and determines the three-dimensional coordinates of a plurality of surface points. At least one rendered image of the three-dimensional geometry of the viewed object is displayed simultaneously with the two-dimensional image. As measurement cursors are placed and moved on the two-dimensional image, the rendered image of the three-dimensional geometry of the viewed object is automatically updated.

displaying a two-dimensional image of the object surface on a display;
determining three-dimensional coordinates of a plurality of points on the object surface using a central processor unit;
determining a rendered image of the three-dimensional coordinates of at least a portion of the object surface using the central processor unit, the rendered image is output on the display;
displaying, responsive to user input, measurement cursors on the rendered image;
displaying, on the two-dimensional image:
measurement identifiers corresponding to the measurement cursors displayed on the rendered image, and
a measurement line identifier extending from one of the measurement identifiers to at least an additional one of the measurement identifiers; and
simultaneously displaying the two-dimensional image and the rendered image on the display.
2. The method of claim 1 , further comprising:
determining a measurement dimension of the object surface based on the locations of the measurement cursors on the rendered image using the central processor unit.
3. The method of claim 1 , wherein the rendered image is a depth profile image.
4. The method of claim 1 , wherein the rendered image is a point cloud view.
5. The method of claim 1 , wherein the step of determining of the three-dimensional coordinates of the plurality of points on the object surface using the central processor unit is performed using structured-light techniques and begins before placing a plurality of measurement cursors on the rendered image.
6. The method of claim 5 , wherein the determining of the three-dimensional coordinates of the plurality of points on the object surface using the central processor unit is completed before the placing of the measurement cursors on the rendered image.
7. A device for inspecting an object surface of a viewed object, the device comprising:
an elongated probe comprising an insertion tube;
an imager located at a distal end of the insertion tube for obtaining a two-dimensional image of the object surface;
a display;
a central processor unit;
a memory storing non-transitory computer readable program instructions, which when executed by the central processor unit cause the central processor unit to perform operations including:
displaying the two-dimensional image of the object surface on the display;
determining three-dimensional coordinates of a plurality of points on the object surface;
determining a rendered image of the three-dimensional coordinates of at least a portion of the object surface, the rendered image is output on the display;
displaying, responsive to user input, measurement cursors on the rendered image;
displaying, on the two-dimensional image:
measurement identifiers corresponding to the measurement cursors displayed on the rendered image, and
a measurement line identifier extending from one of the measurement identifiers to at least an additional one of the measurement identifiers; and
simultaneously displaying the two-dimensional image and the rendered image on the display.
8. The device of claim 7 , wherein the instructions, when executed, further cause the central processor unit to perform operations including:
determining a measurement dimension of the object surface based on locations of the measurement cursors on the rendered image.
9. The device of claim 7 , wherein the rendered image is a depth profile image.
10. The device of claim 7 , wherein the rendered image is a point cloud view.
11. The device of claim 7 , wherein the instructions, when executed, further cause the central processor unit to perform determining the three-dimensional coordinates of the plurality of points on the object surface using structured-light techniques before placing a plurality of measurement cursors on the rendered image.
12. The device of claim 11 , wherein the instructions, when executed, further cause the central processor unit to complete the determining of the three-dimensional coordinates of the plurality of points on the object surface before the placing of the measurement cursors on the rendered image.
13. A non-transitory computer readable storage medium containing program instructions, which when executed by a central processor unit cause the central processor unit to perform operations comprising:
displaying a two-dimensional image of an object surface on a display;
determining three-dimensional coordinates of a plurality of points on the object surface;

a measurement line identifier extending from one of the measurement identifiers to at least an additional one of the measurement identifiers; and
simultaneously displaying the two-dimensional image and the rendered image on the display.
14. The non-transitory computer readable storage medium of claim 13 , wherein the program instructions further cause the central processor unit to perform operations including:
determining a measurement dimension of the object surface based on locations of the measurement cursors on the rendered image.
15. The non-transitory computer readable storage medium of claim 13 , wherein the rendered image is a depth profile image.
16. The non-transitory computer readable storage medium of claim 13 , wherein the rendered image is a point cloud view.
17.
