The invention discloses a method and device for preventing peeping of holographic projection images. The method includes: calculating and obtaining the rough adjustment distance of the second device according to the parameters of the holographic projection image, and sending the rough adjustment distance to the second device; responding to the second The distance adjustment confirmation message returned by the device, according to the parameters of the holographic projection image, calculates the fine-tuning angle and light adjustment intensity of the interference light; transmits the interference light with the light adjustment intensity to the second device, and at the same time sends an angle adjustment message to the second device , the angle adjustment message includes a fine-tuning angle, so that the second device adjusts the direction of the interfering light according to the fine-tuning angle. By sending the coarse adjustment distance to the second device, the second device can prompt the user to adjust the position of the second device, transmit the interference light with the intensity of illumination adjustment to the second device, and inform the second device to adjust the angle of the interference light by fine-tuning the angle direction, so that the interfering light can interfere with the sight of bystanders, achieve the effect of anti-peeping, and ensure the privacy of user information.
Description
technical field [0001] The invention relates to the field of holographic and projection display technologies, in particular to a method and device for preventing peeping of holographic projection images. Background technique [0002] Holographic projection is a technology of three-dimensional imaging in the air. Unlike flat screen projection, which only achieves a three-dimensional effect on a two-dimensional surface through perspective and shadow effects, holographic projection technology is a real 3D image that can be viewed from any angle of 360°. View different sides of the image. It is usually a four-dimensional cone made of transparent materials. The light source is projected from the bottom projection source. The viewer's line of sight can penetrate it from any side. Through the principle of surface reflection, the viewer can see freely floating images from inside the cone-shaped space. 360° holographic projection images are more and more favored by users due to thei...
