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
View Patent ↗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 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 depth profile image of a three-dimensional geometry of at least a portion of the object surface using the central processor unit;
simultaneously displaying the two-dimensional image and the depth profile image on the display;
placing a plurality of measurement cursors on the two-dimensional image using a pointing device and displaying the plurality of measurement cursors on the two-dimensional image on the display;
displaying on the depth profile image a plurality of measurement identifiers corresponding to the measurement cursors on the two-dimensional image; and
determining a measurement dimension of the object surface based on the locations of the plurality of measurement cursors on the two-dimensional image using the central processor unit.
2. The method of claim 1 , wherein the two-dimensional image is one of a first or a second stereo image.
3. The method of claim 1 , wherein the measurement dimension is a depth of a feature on the object surface relative to a reference surface determined using three-dimensional coordinates proximate to one or more of the plurality of measurement cursors.
4. The method of claim 2 , 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 two-dimensional image.
5. The method of claim 4 , 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 two-dimensional image.
6. The method of claim 1 , further comprising changing locations of the plurality of measurement cursor on the two-dimensional image, wherein the changing of locations of the plurality of measurement cursors automatically includes changing locations of the plurality of measurement identifiers on the depth profile.
7. The method of claim 1 , wherein determining the three-dimensional coordinates is based on calibration data that includes optical characteristics data.
