Technical Field

The invention belongs to the technical field of camouflage painting devices, and particularly relates to a camouflage painting device suitable for various natural backgrounds.

Background

At present, camouflage net surfaces, camouflage clothing surfaces and camouflage paint have similar color and spectral reflection characteristics with the background, so that weapons or personnel can be blended into the background, and therefore, enemies can hardly find the camouflage net surfaces, the camouflage clothing surfaces and the camouflage paint.

However, after the season or the battle area changes, the camouflage surface needs to be changed correspondingly, for example, when military vehicles move from the northwest gobi area to the southeast coast of China, the desert camouflage color on the surface needs to be changed into the forest type camouflage color. Traditionally, it has been necessary to re-spray camouflage coatings on military vehicle surfaces and to replace desert type camouflage nets with forest land type camouflage nets. The traditional method is high in cost, and the spraying operation influences the fighting timeliness of equipment.

Various techniques have been developed to improve the background adaptability of camouflage surfaces. The more mature technology is double-sided camouflage net. The decorative cloth of the double-sided camouflage net has different colors on the front and the back, usually the front faces are outwards designed forest land patterns, and the back faces are used as desert patterns, but the scheme is only suitable for 2 kinds of backgrounds, and the number of the suitable backgrounds is small.

In order to enable the camouflage surface to adapt to more backgrounds, the skilled person develops a color-changing material with the help of the material, but the color-changing material cannot cover all backgrounds, cannot realize multiband compatible camouflage, cannot meet the requirements of hyperspectral camouflage, and is difficult to accurately control colors and color differences.
