Mosaic oblique images and methods of making and using same
First Claim
1. A system comprising:
- a computer system running image processing software that when executed by the computer system causes the computer system to;
receive an identification of a desired area to be imaged and collected into an oblique-mosaic image;
create a mathematical model of a virtual camera having a sensor higher in elevation from which source oblique images were captured and looking down at an oblique angle, the mathematical model having an oblique-mosaic pixel map for the sensor of the desired area encompassing multiple source images;
assign a surface location to each pixel included in the oblique-mosaic pixel map;
select source oblique images of geographic coordinates captured at an oblique angle and compass direction similar to the oblique angle and compass direction of the virtual camera; and
reproject at least one source oblique image pixel of the area to be imaged for each pixel included in the oblique-mosaic pixel map in a fan-like pattern to thereby create an oblique-mosaic image of the desired area.

Abstract
A system, including a computer system running image processing software, receives an identification of a desired area to be imaged and collected into an oblique-mosaic image. The computer system creates a mathematical model of a virtual camera having a sensor higher in elevation from which the source oblique images were captured and looking down at an oblique angle, the mathematical model having an oblique-mosaic pixel map for the sensor of the desired area encompassing multiple source images. The computer system assigns a surface location to each pixel included in the oblique-mosaic pixel map and selects source oblique images of the geographic coordinates captured at an oblique angle and compass direction similar to the oblique angle and compass direction of the virtual camera. The computer system reprojects at least one source oblique image pixel of the area to be imaged for each pixel included in the oblique-mosaic pixel map to create the oblique-mosaic image.

11. A system comprising:
a computer system running image processing software that when executed by the computer system causes the computer system to; receive an identification of a desired geographical area to be imaged and collected into an oblique-mosaic image; create a mathematical model of a virtual camera having a sensor, where the virtual camera has an elevation greater than an elevation from which source oblique images were captured and looking down at an oblique angle, the mathematical model having an oblique-mosaic pixel map for the sensor of the desired area encompassing multiple source oblique images; determine geographic coordinates for pixels included in the oblique-mosaic pixel map; select source oblique images of the geographic coordinates captured at an oblique angle and compass direction similar to the oblique angle and compass direction of the virtual camera; and reproject, using a mathematical elevation model to define a ground surface within the desired geographical area, at least one source oblique image pixel of the selected source oblique images of the area to be imaged from a vantage point of the sensor of the virtual camera for each pixel included in the oblique-mosaic pixel map in a fan-like pattern to thereby create a geo-referenced oblique-mosaic image of the desired geographical area. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
