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.
