Method and apparatus for capturing geolocating and measuring oblique images
First Claim
1. A computerized system for displaying and making measurements based upon captured oblique images, comprising:
- a computer system executing image display and analysis software reading;
a plurality of captured oblique images having corresponding geo-location data; and
a data table storing ground plane data that closely approximates at least a portion of terrain depicted within said captured oblique images;
at least one display device adapted to display one or more of the plurality of captured oblique images; and
at least one input device adapted to permit selection of one or more points within the plurality of captured oblique images,wherein the image display and analysis software when executed by the computer system causes the computer system to display at least one of the captured and geo-located oblique images;
wherein the image display and analysis software is adapted to, in response to selection of two or more points via the input device, select one or more intermediate points positioned between the two or more selected points to thereby form a plurality of line segments connecting the two or more selected points, each line segment, using the ground plane data, following the terrain depicted within the portion of the captured oblique image corresponding to that line segment, andwherein the image display and analysis software is adapted to calculate a distance along said line segments between the two or more selected points.

Abstract
A computerized system for displaying, geolocating, and taking measurements from captured oblique images includes a data file accessible by the computer system. The data file includes a plurality of image files corresponding to a plurality of captured oblique images, and positional data corresponding to the images. Image display and analysis software is executed by the system for reading the data file and displaying at least a portion of the captured oblique images. The software retrieves the positional data for one or more user-selected points on the displayed image, and calculates a separation distance between any two or more selected points. The separation distance calculation is user-selectable to determine various parameters including linear distance between, area encompassed within, relative elevation of, and height difference between selected points.

14. A computerized method for taking measurements within a displayed oblique image, comprising:
-
receiving, from an input device, a selection of a starting point and an end point on the displayed image; retrieving from a data file positional data corresponding to the starting and end points; referencing a ground plane data file storing ground plane data that closely approximates at least of portion of terrain depicted within said displayed image; connecting the starting point and the end point with a plurality of line segments, the line segments conforming to the ground plane data to thereby follow the terrain; and calculating the distance along the line segments between the starting point and the end point thereby taking into account said ground plane data of said line segments. - View Dependent Claims (15, 16)
