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 and device 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.
1. A method for inspecting an object surface of a viewed object, the method comprising the steps of:
displaying a two-dimensional stereo 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 using stereo techniques;
determining a rendered image of the three-dimensional coordinates of at least a portion of the object surface using the central processor unit;
placing a plurality of measurement cursors on the rendered image using a pointing device and displaying the plurality of measurement cursors on the rendered image on the display;
displaying on the two-dimensional stereo image a plurality of measurement identifiers corresponding to the measurement cursors on the rendered image;
determining a measurement dimension of the object surface based on the locations of the plurality of measurement cursors on the rendered image using the central processor unit; and
simultaneously displaying the two-dimensional stereo image and the rendered image on the display.
2. The method of claim 1 , wherein the two-dimensional image stereo is one of a first or a second stereo image.
3. The method of claim 1 , further comprising the steps of:
placing a plurality of measurement cursors on the two-dimensional stereo image using a pointing device and displaying the plurality of measurement cursors on the two-dimensional stereo image on the display;
displaying on the rendered image a plurality of measurement identifiers corresponding to the measurement cursors on the two-dimensional stereo image; and
determining a measurement dimension of the object surface based on the locations of the plurality of measurement cursors on the two-dimensional stereo image using the central processor unit.
4. The method of claim 1 , wherein the rendered image is a depth profile image.
5. The method of claim 1 , wherein the rendered image is a point cloud view.
6. The method of claim 1 , wherein the step of determining the three-dimensional coordinates of a plurality of points on the object surface using a central processor unit begins before the step of placing a plurality of measurement cursors on the rendered image.
7. The method of claim 6 , wherein the step of determining the three-dimensional coordinates of a plurality of points on the object surface using a central processor unit is completed before the step of placing a plurality of measurement cursors on the rendered image.
8. 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 stereo image of the object surface;
a central processor unit configured to perform operations including:
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,
placing a plurality of measurement cursors on the rendered image based on an input received using a pointing device and displaying the plurality of measurement cursors on the rendered image on the display,
displaying on the two-dimensional stereo image a plurality of measurement identifiers corresponding to the measurement cursors on the rendered image, and
determining a measurement dimension of the object surface based on the locations of the plurality of measurement cursors on the rendered image using the central processor unit; and
a display for simultaneously displaying the two-dimensional stereo image and the rendered image.
