Anti Japanese Victory, 70Th Anniversary Parade Ceremony Presents Discoloration Camouflage Suit

During the Victory Day parade, the multi terrain camouflage costume showed a magical "discoloration" effect under different lighting conditions.

"When the parade team passed the Tiananmen, why the color of the multi terrain camouflage was yellow, which is not the same as the yellow green color. Is this dress a chameleon?" after the 9 3 parade, the editorial department of the Chinese army network received a telephone call from the enthusiastic netizens, asking questions about the multi terrain fans.

The reporter interviewed specially the camouflage for this parade.

The following is a question and answer list of the senior engineer of Shaw Hong, a general post office equipment research institute.

Q: the multi terrain camouflage has not been seen before in the army. Is this parade the first public appearance? Where is it really good?

Answer: multi terrain camouflage, full name, multi terrain camouflage.

The parade is the first public display. It is suitable for individual combat camouflage on the ground and near ground background.

Multi terrain camouflage is a camouflage with three dimensional, multi-color, and visual illusions. It can adapt to many kinds of terrain such as woodland, desert, city or camouflage needs of open combat background mixed with many terrain features.

Multi terrain camouflage combat clothing has high strength, wear resistance and good color fastness and other physical and chemical properties.

The multi terrain camouflage flame fighting clothing adopts self-developed, low price, easy dyeing, synergistic effect and multi fiber blended flame retardant fabric, which has high cost performance, and solves the problem of high cost and easy dyeing of flame retardant fabrics.

A: unlike most specialized parade clothing, multi terrain camouflage is a long established military research project and is not specially designed for this parade.

In June 2015, the multi terrain camouflage received the affirmation of the head of the general assembly and the head of the general post, indicating that the suit in the research should be unveiled in advance in the 9 3 parade. The range of dress was also extended from a previously designed walking team to two walking teams and two equipment teams.

Multi terrain camouflage itself does not have the function of "discoloration", but there is "discoloration effect" caused by visual illusion.

That is to say, under the yellow background, the Yellow parts and patterns of multi terrain camouflage will be highlighted; under the green background, the green parts and patterns of multi terrain camouflage will be highlighted.

On the day of parade, the sun was strong, the ground background was light yellow and cement, the suit looked lighter and yellowish, but in a darker environment, because of its low brightness, the clothes would be greenish brown, suitable for woodland with darker shade of green dominated background. This may be the reason why people call it "chameleon".

Q: what is the design principle of multi terrain camouflage? Is it different from the previous camouflage clothes?

A: multi terrain camouflage is designed based on the principles of visual cognition physiology, cognitive psychology and optical illusion. It can better meet the camouflage needs of various terrain, such as woodland, desert and city, as well as mixed terrain background.

Compared with past traditional big camouflage camouflage and digital camouflage, the design of multi terrain camouflage is based on the following basic cognition: single soldier camouflage should be based on the ground and near ground background; the natural background is three-dimensional; the color of nature is rich and varied, such as green, at least in the same period, same vegetation or different seasons, there are at least three kinds of lightness, shade and shade green.

The color is controlled by different colors and patterns of patches, so as to achieve the camouflage of human body shapes, but the shadow of the human body is still unavoidable in the sunlight. The whole body contour of the human body is still easy to be detected and detected. The strong control plaques of the clothes are easy to cause visual attention. Nowadays, the multi terrain camouflage uses color and patch to fuse and gradually pition, simulating the nature as much as possible, and achieving camouflage in this way. In other words, two camouflages are placed in the same background, that is, two you can see, but you will first notice the contrast camouflage, namely the traditional camouflage, and you will feel that multi terrain camouflage is part of the natural world, even if it is discovered, it will also ignore it. Previous camouflage, such as 07 digital puzzle.

Q: the main function of camouflage is camouflage. What is the camouflage effect of multi terrain camouflage?

A: first of all, multi terrain camouflage simulates natural camouflage through multicolored gradient camouflage.

Through the comprehensive application of a variety of gradient interpenetration, mud point superposition, light coloured highlights and dark shadows, the multicolored gradual camouflage has rich color levels, gradually changing colors, overlapping each other, and blurring the outline of the edges.

Secondly, we use visual cognition theory to disguise.

Using the three dimensional visual error, bottom conversion and color error design of the pattern, the multi terrain camouflage patterns show the characteristics of three-dimensional, multi-level, yellow and green appearing in the respective background, the corresponding color area expansion, and the mutual pformation of patterns and background colors.

This avoids the visual attention caused by the strong color and contour contrast of the camouflage pattern, making the multi terrain camouflage very natural.

Again, camouflage is done by balancing the size and color of space.

Finally, spectral camouflage is achieved by dispersion of spectral reflectance.

The comprehensive effect of the above camouflage technology is that when observing the multi terrain camouflage in the background, multi terrain camouflage will make the contour of the human body blurred and blend into the surrounding environment. Even if the observer finds anything, it will feel that it is only a part of nature and can not be clearly identified.

Q: after the parade, the multi terrain camouflage is refreshing. The effect of "suction eye" is obvious. It certainly contains a lot of hard work of science and technology personnel. Can you talk about the specific research and development process?

Answer: in the study of individual soldier camouflage theory, based on the analysis of individual soldier's technical movement, the project group carried out a large number of observation and image analysis on the ground background of the typical background such as the jungle, desert and woodland, and compared the camouflage patterns, characteristics and development history of more than 20 countries in different historical periods and different battlefield situations.

In the aspect of camouflage pattern design, experts from the project team rushed to collect the relevant ground object spectral data in different time, different locations and different operational backgrounds under typical combat background, and established the colorimetric indexes of main colors in the visible and near infrared regions.

After more than 30 rounds of drawing, evaluation, printing and modification, the camouflage pattern was finally determined.

In the printing process, the reflectance of the substrate in the near infrared band is reduced by special means to meet the requirement of near infrared camouflage.

In the course of development, Shi Mei Wu Gao put forward the idea of applying visual cognition theory to camouflage. The Wang Yan engineer carried ten sets of camouflage of our army and foreign army to carry out camouflage effect evaluation in all parts of the country. I am the head of this project. In recent years, I have been insisting on collecting spectral curves of typical objects in different places at different times, seasons and places.

In 2013, during the visit of foreign countries, I made a systematic study of the history, typical features and color patches of the camouflage.

In addition, the development of multi terrain camouflage clothes has been strongly supported by various cooperation units. Thanks to Professor Xue Mei and Professor Zhang Xuemin of Beijing Normal University, Beijing Union University.
