System and process for color-balancing a series of oblique images

摘要

Image processing systems and methods are disclosed, including an image processing system comprising a computer running image processing software causing the computer to receive an oblique aerial image having at least a first section and a second section, wherein the first section has a first color distribution and the second section has a second color distribution; receive at least two reference images having consistent color distributions; receive geographic information about the at least two reference images and the oblique aerial image; choose at least a one reference image for each of the first and second sections based on the geographic information; and create at least one color-balancing transformation for the first and second sections.

主权项

1. An image processing system, comprising:
a computer running image processing software causing the computer to:
receive an oblique aerial image, the oblique aerial image having at least a first section and a second section, wherein the first section has a first color distribution and the second section has a second color distribution, the first color distribution differing from the second color distribution;receive at least two reference images, each reference image having a consistent color distribution;receive geographic information about the at least two reference images and the oblique aerial image;choose at least a first chosen reference image from the at least two reference images for the first section of the oblique aerial image, based on automatically matching at least a portion of the geographic information of the oblique aerial image with at least a portion of the geographic information of the first chosen reference image;choose at least a second chosen reference image from the at least two reference images for the second section of the oblique aerial image, based on automatically matching at least a portion of the geographic information of the oblique aerial image with at least a portion of the geographic information of the second chosen reference image;create at least one color-balancing transformation for the first section of the aerial oblique image such that the first color distribution of the first section matches the consistent color distribution of the first chosen reference image; andcreate at least one color-balancing transformation for the second section of the aerial oblique image such that the second color distribution of the second section matches the consistent color distribution of the second chosen reference image.
