According to the Russian headline news network, the Russian army plans to install color changing camouflage for armored vehicles, so that they can quickly change the body color according to the surrounding environment and better protect themselves from enemy detection. Change is done in an instant It is reported that the color changing camouflage is developed by the Russian Electronics Holding Company under the Russian State Technology Group Company. The whole system consists of several independent sheets, and the surface of the sheet is covered with electrochromic camouflage. "It can produce a variety of visual images to imitate the color and structure of the surrounding environment, so as to achieve the color change effect." It is reported that the above discoloration effect is realized with the help of advanced image acquisition and computer control technology. The color changing camouflage system includes multiple cameras, which can collect the image information of the external environment of the vehicle in real time and transmit it to the main control computer. After analyzing the image information at high speed, the computer can control the electrochromic camouflage to adjust and produce a camouflage image suitable for the environment. It is reported that the discoloration process under computer control is very fast. "Color changing camouflage can make an instantaneous response to environmental changes and complete it in a few tenths of a second. For example, an armored vehicle is parked in the field with camouflage colors and patterns similar to the surrounding environment. When it changes its position and the background is changed to another landscape, the computer will control the color changing camouflage system to quickly change the color and structure to help the tank integrate into the background." The real "invisible killer" Russian electronic holding company announced that the above color changing camouflage system is still in the research and development stage and is currently being tested on the equipment model. After successful research and development, the new camouflage will be widely used in tanks, infantry vehicles, armored personnel carriers, etc. "The new camouflage can help armored vehicles integrate with the background, making the enemy's optical reconnaissance equipment unable to work normally. At that time, even trained professionals will find it difficult to identify them with the naked eye at a long distance. It is also difficult for optical reconnaissance platforms such as satellites, UAVs and manned reconnaissance aircraft to track them. Such tanks and armored vehicles will become real" stealth killers " ’。” In fact, as early as 2018, Russian Electronics Holding Company showed an electrochromic material to the outside world. The material is ordered by the Russian Ministry of defense to develop and change colors and camouflage patterns according to the environment. Sergei chermezov, President of Russian State Technology Group, believes that this color changing material has broad development prospects and can be used in military uniforms and combat equipment in the future. The media speculated that the discoloration camouflage displayed by Russian media this time is a further promotion of previous research results, "another step closer to actual combat". However, some media believe that the research and development of color changing camouflage is very difficult. Even if it is successful, it is difficult to popularize and apply it on a large scale. The US military has launched similar projects, but they have not achieved ideal results. DARPA has launched a "chameleon project" and developed a "deformation coat" composed of advanced sensors and display panels. After wearing this "coat", the tank can automatically adjust its color and shape according to the changes of environment and light, so that it is difficult for the naked eye and optical telescope to recognize its true contour. The U.S. military has sent three Stryker armored vehicles equipped with "deformation coats" to the Afghan battlefield for testing, with obvious results. "Beside the bare stone, it is like a stone; in the jungle, it becomes a bush." It should be pointed out that this "deformation coat" is bulky and delicate, and the collision of shrapnel once made it fail. (outlook new era)
