Method and Apparatus for Capturing, Geolocating and Measuring Oblique Images
First Claim
1. A computerized system for displaying, geolocating, 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;
geo-location data corresponding to said plurality of captured oblique images; and
tessellated ground plane data that closely approximates at least a portion of the terrain depicted within said captured oblique images, said tessellated ground plane data further comprising a plurality of interconnected facets with the size of the facets defined using a uniform number of pixels in the captured oblique images; and
wherein the image display and analysis software displays one of the captured and geo-located oblique images and calculates a geo-location of one or more selected points within said displayed image, said software calculating a separation distance between any two or more selected points within said displayed image.

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.

30. A method of capturing oblique images of an area of interest with an image-capturing device carried by a platform, said method comprising:
-
guiding the platform along a first path to thereby target one or more target sectors with the image-capturing device; capturing with the image-capturing device one or more oblique images to thereby cover an entirety of each said target sector in oblique images captured from a first perspective; guiding the platform along a second path to thereby target said target sectors;
capturing with the image-capturing device one or more oblique images to thereby cover an entirety of each said target sector in oblique images captured from a second perspective;repeating said guiding and capturing steps along paths substantially parallel to and spaced apart from said first and second paths and capturing one or more oblique images to thereby cover an entirety of each of said plurality of sectors in oblique images captured from each of said first and second perspectives; and recording geo-location data indicative of a geo-location of said image-capturing device. - View Dependent Claims (31, 32, 33, 34, 35)
