The invention relates to a medium-long-wave dual-waveband infrared image feature level color fusion method. The method comprises: for a same scene signal, obtaining long-wave infrared image signal data and medium-wave infrared image signal data of a medium-long-wave dual-waveband infrared imaging system; performing dual-waveband difference feature extraction and HIS spatial fusion on the long-wave infrared image signal data and the medium-wave infrared image signal data: setting a threshold T and performing calibration and fusion calculation on components S and H of a difference part of medium-wave and long-wave images in an HIS chromaticity space; and converting HIS spatial fusion information data to an RGB space so as to obtain feature level color fusion data. According to the method, detailed information of an original image and feature information after color fusion extraction have been retained effectively, so that the image contains richer information and the identification efficiency of a specific scene target is remarkably improved.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a feature-level color fusion method for medium and long-wave dual-band infrared images. Background technique [0002] Different band images will contain different information details, let these details be presented in one image and avoid false information as much as possible, and finally obtain an image with rich spectral information, clear details and easy to identify, which is already the current infrared imaging technology. An urgent need for technology. [0003] Until the 1990s, the early multi-spectral color night vision systems in Japan, Europe, America and other countries were not suitable for long-term observation due to the limitation of the number of spectra and bands, and the color distribution obtained by simple fusion method was inconsistent with the actual scene. . From the mid-to-late 1990s to the beginning of the 20th century, natural color night vision processin...
