Wavelength diverse scintillation reduction

摘要

Systems, including apparatus and methods, for obtaining and/or correcting images, particularly from atmospheric and/or other distortions. These corrections may involve, among others, collecting two or more sets of image data corresponding to images of the same scene in different wavelength regimes, and using correlations between wavelength and expected distortion to distinguish apparent image motion due to distortion from apparent image motion due to object or scene motion. These systems may be useful in any suitable imaging context, including navigation, targeting, search and rescue, law enforcement, commercial video cameras and/or surveillance, among others.

主权项

1. A method of image correction, comprising:
collecting image data in a range of wavelengths that includes at least a first wavelength and a second wavelength; processing the image data to determine a first apparent motion map from image data collected at the first wavelength and a second apparent motion map from image data collected at the second wavelength; processing the first and second apparent motion maps to distinguish changes caused by wavelength-dependent distortion from changes caused by object motion; generating a first set of corrected image data by removing changes caused by wavelength-dependent distortion from the collected image data; and generating a first corrected image from the first set of corrected image data.
