cloaking device

Abstract

A cloaking device, comprising: a control processing unit, more than one camera device, and a display unit arranged on the surface of a target object, each pixel of the display unit includes more than two sub-pixels, and the light emission of each sub-pixel has directivity and each The light-emitting angles of the sub-pixels are connected to each other and fill the preset space angle. Each camera device captures the scene images around the target object, and the control processing unit stitches and fuses the scene images captured by each camera device into a complete image around the target object. The image corresponding to the sub-pixel corresponding to the image of the intersection point of the reverse extension line of the axis line of the light-emitting direction and the background is used as the basis to establish the corresponding relationship between each sub-pixel and the coordinates of the complete image, and control the coordinates of each sub-pixel in the complete image according to the corresponding relationship. An image corresponding to a pixel is displayed on each corresponding sub-pixel. The cloaking device of the present invention can keep the images viewed from different directions consistent with the covered background all the time, and realize the all-round cloaking of the target object.

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...
