System and process for color-balancing a series of oblique images |
摘要 |
An automated process for color-balancing a series of oblique images captured from one or more positions and from one or more orientations. The automated process includes the step of selecting a series of color-balanced images to use as reference images. Then, on an oblique image by image basis (1) a portion(s) of a reference image(s) that overlaps the oblique image is located, (2) multiple color-balancing transformations are created that approximately matches the color distribution of the oblique image to the color distribution of the overlapping portion(s) of the reference image(s), (3) pixels in the oblique image are transformed according to the multiple color-balancing transformations created for that oblique image; and (4) the transformed pixel value is transformed in the oblique image or a copy of the oblique image. |
