Image data fusion systems and methods

摘要

Systems and methods for image data fusion include providing first and second sets of image data corresponding to an imaged first and second scene respectively. The scenes at least partially overlap in an overlap region, defining a first collection of overlap image data as part of the first set of image data, and a second collection of overlap image data as part of the second set of image data. The second collection of overlap image data is represented as a plurality of image data subsets such that each of the subsets is based on at least one characteristic of the second collection, and each subset spans the overlap region. A fused set of image data is produced by an image processor, by modifying the first collection of overlap image data based on at least a selected one of, but less than all of, the image data subsets.

1. A method for image data fusion, comprising:
receiving a first set of image data as at least one first data channel and corresponding to a first imaged first scene; receiving a second set of image data as at least one second data channel and corresponding to a second imaged second scene that at least partially overlaps said first scene in an overlap region, converting at least a portion of the first set of image data corresponding to the overlap region from at least one of the at least one first data channels formats into a plurality of first frequency subsets within a transform domain by applying a first forward transformation; converting at least a portion of the second set of image data corresponding to the overlap region from at least one of the at least one second data channels into a plurality of second frequency subsets within the transform domain by applying a second forward transformation; and producing a fused set of image data by replacing at least one of the plurality of first frequency subsets with a corresponding at least one of the plurality of second frequency subsets of a selected second data channel; wherein: each of the plurality of first and second frequency subsets correspond to one of a plurality of frequency sub-bands, and the converting and receiving steps are performed by an image processor, and the step of converting the second set includes filtering at least the data from the selected second data channel corresponding to the overlap region, and the first set of image data is received from a color camera and the second set of image data is received from a grayscale camera.
