Height measurement in a perspective image
First Claim
1. A method for identifying a location in a scene, the method comprising:
- displaying an image of the scene on a display device;
moving a cursor on the image in relation to a number of corresponding directions in a model of the scene in response to a manipulation of a number of displayed controls indicating possible cursor motions;
responsive to a user input selecting a particular point in the image, identifying a base location in the scene corresponding to the particular point so as to identify a row and a column for the particular point;
responsive to another user input occurring after identification of the base location, selecting a selected point in the image for the scene, and identifying a displacement of the selected point from the base location; and
identifying an offset location in the scene corresponding to the selected point in the image using the base location and the displacement.

Abstract
A method, apparatus, and computer program product are present for identifying a location in a scene. An image of the scene is displayed on a display device. A cursor on the image is moved in relation to a number of corresponding directions in a model of the scene in response to a manipulation of a number of controls associated with the cursor. A base location in the scene is identified corresponding to a particular point in response to a user input selecting the particular point in the image. A selected point in the image is selected for the scene and a displacement of the selected point is identified from the base location in response to another user input occurring after an identification of the base location. An offset location in the scene is identified corresponding to the selected point in the image using the base location and the displacement.

24. A non-transitory computer program product for identifying a location in a scene, the computer program product comprising:
-
a computer recordable storage medium; program code, stored on the computer recordable storage medium, for displaying an image of the scene on a display device; program code, stored on the computer recordable storage medium, for moving a cursor on the image in relation to a number of corresponding directions in a model of the scene in response to a manipulation of a number of controls associated with the cursor; program code, stored on the computer recordable storage medium, responsive to a user input selecting a particular point in the image, for identifying a base location in the scene corresponding to the particular point so as to identify a row and a column for the particular point; program code, stored on the computer recordable storage medium, responsive to another user input occurring after an identification of the base location, for selecting a selected point in the image for the scene, and identifying a displacement of the selected point from the base location; and program code, stored on the computer recordable storage medium, for identifying an offset location in the scene corresponding to the selected point in the image using the base location and the displacement.
