Dynamic infrared camouflage can need to change according to the background, and quickly from a state of camouflage into another state of camouflage. The image characteristics of various infrared camouflage states weak correlation, can make the infrared surveillance and tracking, target infrared characteristics of the real difficulty of the guidance system, unable to complete the target reconnaissance and combat, so as to improve the battlefield survivability of the target. According to different background conditions, infrared camouflage algorithm is adopted to realize infrared camouflage for equipment, so that equipment and background can be integrated. The evaluation of camouflage effect needs to be carried out through corresponding methods. Based on the principles of evaluation index selection, and given to evaluation object, evaluation purpose and evaluation method, constructs the evaluation index system, comprehensive selection of brightness contrast and color features, texture features three evaluation indexes. Combined with the specific test, the infrared camouflage effect was evaluated, the indicators were analyzed, and all the indicators were comprehensively analyzed according to the weight value. Finally, the optimal state for the comprehensive evaluation of the camouflage effect was given.
