Methods of opto-electronic fusion of infrared and visible images
Abstract
The interpretation of images could be greatly facilitated by simultaneously considering the images of the same scene produced by captors of different types. Thus, a global approach to the problem of opto-electronic fusion between two captors, infrared (IR) and visible, is arrived at here, with three levels of association of data. The fusion of data can be made at the decision making level (class of objects), at the intermediary level (elementary objects), and finally at the level that the signal is issued directly to the captors. At each step of fusion, the problem of the placement in the correspondence of the IR and visible data is posed. This alignment must be as much or more precise as the level of data. The preliminary phase of treatment strongly affects the fusion step. The rules of fusion are developed in such a way as to improve the power of classification, augmenting the probability of detection, utilizing the eventual complementarity of the captors, and permitting a simultaneous visualization of pertinent IR and visible information to the operator.
