Method and device for determining geometric property
First Claim
1. A method for determining a geometric property of an object, the method comprising:
- displaying an image of the object on a touchscreen;
receiving touch data via the touchscreen;
automatically identifying a plurality of cursor points in the touch data using a processor;
automatically determining a measurement type of the geometric property using the touch data;
automatically determining the geometric property corresponding to the plurality of cursor points and the determined measurement type using the processor; and
wherein the cursor points include respective two-dimensional (2-D) coordinates in the image of the object, and the geometric-property-determining step includes;
determining three-dimensional (3-D) coordinates of the object using the image of the object;
selecting a plurality of the 3-D coordinates corresponding to the 2-D coordinates of the cursor points; and
determining the geometric property using the selected plurality of the 3-D coordinates.

Abstract
A method for determining a type of a measurement includes receiving touch data via a touchscreen; automatically identifying a plurality of cursor points in the touch data using a processor; and automatically determining a measurement type based on the touch data using the processor. A method for determining a geometric property of an object further includes displaying an image of the object on the touchscreen and automatically determining the geometric property corresponding to the plurality of cursor points and the determined measurement type using the processor. A device for determining the geometric property includes an imager for obtaining the image; the touchscreen; and the processor for identifying a plurality of cursor points in the touch data, determining a measurement type of the geometric property using the touch data, and automatically determining the geometric property corresponding to the plurality of cursor points and the determined measurement type.

9. A method for determining a geometric property of an object, the method comprising:
-
displaying an image of the object on a touchscreen; receiving touch data via the touchscreen; automatically identifying a plurality of cursor points in the touch data using a processor; automatically determining a measurement type of the geometric property using the touch data; automatically determining the geometric property corresponding to the plurality of cursor points and the determined measurement type using the processor; and wherein the measurement-type-determining step includes determining that the measurement type is; a) a length measurement if the touch data consist of one or more substantially connected touch paths that substantially form an open path, each of the touch paths including one or more substantially straight segments; b) a depth-profile measurement if the touch data consist of one substantially curved touch path; c) a perpendicular-distance measurement if the touch data consist of one substantially straight touch path and one tap; d) an area measurement if the touch data consist of one or more touch paths that substantially form a closed shape; e) a depth measurement if the touch data consist of one tap and one or more touch paths that substantially form a closed shape;
orf) a surface-offset measurement if the touch data consist of two separated, substantially straight touch paths and one tap.

11. A device for determining a geometric property of an object, the device comprising:
-
a) an imager for obtaining at least one image of the object; b) a touchscreen for displaying the at least one image of the object and for receiving touch data; c) a processor for; i) automatically identifying a plurality of cursor points in the touch data; ii) automatically determining a measurement type of the geometric property using the touch data; and iii) automatically determining the geometric property corresponding to the plurality of cursor points and the determined measurement type; and wherein the processor is configured to determine that the measurement type is; a) a length measurement if the touch data consist of one or more substantially connected touch paths that substantially form an open path, each of the touch paths including one or more substantially straight segments; b) a depth-profile measurement if the touch data consist of one substantially curved touch path; c) a perpendicular-distance measurement if the touch data consist of one substantially straight touch path and one tap; d) an area measurement if the touch data consist of one or more touch paths that substantially form a closed shape; e) a depth measurement if the touch data consist of one tap and one or more touch paths that substantially form a closed shape;
orf) a surface-offset measurement if the touch data consist of two separated, substantially straight touch paths and one tap. - View Dependent Claims (12, 13, 14, 15, 16, 17)
