The interference performance to the target recognition in images from strong light and the suppression of information processing to the strong light interference are researched. And the information processing effect is analyzed quantitatively. Two different research schemes are adopted. The first is strong light interference effect analysis based on base map without interference. The interference image is compared with the visible light image without interference in a same scene. And the interference suppression effect is directly analyzed based on the registered images. The second is strong light interference effect analysis based on target template. The target template is selected for simulation and the recognition levels of the target template under target scene before and after processing are calculated respectively and compared to get the suppression effect of the information processing to strong light interference. The information processing effect can both be quantitatively statistically analyzed through the two research schemes. Processing effect is quantified to provide technology support to information processing technology.
