Hiding device

Abstract

A hiding device comprises a control processing unit, more than one camera devices and a display unit arranged on the surface of a target object, wherein each pixel of the display unit comprises more than two sub-pixels, light emitting of each sub-pixel is directional, the light emitting angles of all the sub-pixels are mutually linked and fill a preset space angle, each camera device takes the scene images around the target object, and the control processing unit splices and combines the scene images taken by the camera devices into a complete image around the target object. Based on the corresponding relationship between the images at the intersected point between the reverse extension long of the axis line of the light emitting direction of each sub-pixel and the background and the sub-pixel, the correspondence relationship between the sub-pixels and the coordinates of the complete image is built, and the image, corresponding to each sub-pixel, in the complete image is controlled to be displayed in the corresponding sub-pixel according to the correspondence relationship. By means of the hiding device, the image watched in different directions is always consistent with the shielded background, so that omni-directional hiding of the target object is achieved.

Description

technical field [0001] The invention relates to the field of stealth technology, in particular to a stealth device. Background technique [0002] Stealth has been a dream of human society for thousands of years. Since the mid-20th century, stealth technology has made amazing progress, and stealth fighters, stealth ships, stealth tanks and other stealth weapons and equipment have appeared. Stealth technologies include radar cloaking, infrared cloaking, magnetic cloaking, acoustic cloaking and visible light cloaking, etc. [0003] Take visible light invisibility as an example. In 2004, a professor at the University of Tokyo in Japan introduced a large coat that uses "visual camouflage" to make it impossible for people to distinguish. It is called "invisibility cloak". Make people "unrecognizable". In fact, the realization principle of the invisibility cloak is as follows figure 1 As shown, the invisibility cloak is made of granular materials coated with retroreflected light...
