Generating a composite field of view using a plurality of oblique panoramic images of a geographic area

摘要

Generating a composite geo-referenced panoramic field of view image of a geographic area is provided. Geodetic coordinates are generated for each of a plurality of pixels in a digital image capturing the geographic area based on a corrected amount of image distortion in each line of pixels in the plurality of pixels in the digital image. Each of the plurality of pixels in the digital image with the calculated geodetic coordinates is mapped to a geo-referenced map corresponding to the geographic area based on the calculated geodetic coordinates of each pixel. The composite geo-referenced panoramic field of view image of the geographic area is generated based on the mapping of each of the plurality of pixels in the digital image with the calculated geodetic coordinates to the geo-referenced map corresponding to the geographic area captured in the digital image.

1. A computer-implemented method for generating a composite geo-referenced panoramic field of view image of a geographic area, the computer-implemented method comprising:
identifying, by a computer, solid angle vectors projecting from a center of Earth along a geographic coordinate system line corresponding to a line of pixels in a digital image capturing the geographic area with known geodetic coordinates associated with a selected set of reference coordinates to form a plurality of solid angles; calculating, by the computer, a distance between a vertical axis and each of the solid angle vectors along the geographic coordinate system line corresponding to the line of pixels in the digital image using a non-linear geographical distance formula; calculating, by the computer, geodetic coordinates of each of a plurality of pixels in the digital image capturing the geographic area based on a corrected amount of image distortion in each line of pixels in the plurality of pixels in the digital image; mapping, by the computer, each of the plurality of pixels in the digital image with the calculated geodetic coordinates to a geo-referenced map corresponding to the geographic area based on the calculated geodetic coordinates of each pixel; and generating, by the computer, the composite geo-referenced panoramic field of view image of the geographic area based on the mapping of each of the plurality of pixels in the digital image with the calculated geodetic coordinates to the geo-referenced map corresponding to the geographic area captured in the digital image.
