Abstract

The invention provides a holographic image imaging method, holographic projection equipment and system, and observation equipment. The holographic image imaging method comprises the following steps of: determining an imaging position of holographic projection imaging according to position information of a main user and other users in a preset area; carrying out holographic image imaging according to the imaging position, and adding a virtual grating with a blank opening and a fence to the peripheral area of holographic image imaging, wherein the blank opening is aligned with the main user, and part or all of the fence is aligned with the other users; and synchronizing the imaging position to observation equipment. According to the method, the holographic projection equipment, the observation equipment and the holographic projection system, the virtual grating is arranged for the main user and other users in the preset area, the blank opening of the virtual grating is aligned with the main user, and the fence is aligned with the other users, so that only the main user can see a 360-degree panorama, and the privacy security of the main user during use of a holographic video is protected.

Description

technical field [0001] The invention relates to the technical field of holographic images, in particular to a holographic image imaging method, holographic projection equipment, observation equipment and a system. Background technique [0002] Different from the existing 180° two-dimensional video display, the holographic image presents a 360° in space. [0003] °Display, with 3D stereoscopic and realism, improves user experience, and at the same time, users can observe holographic images from various angles. [0004] However, for holographic images that require privacy protection, such as holographic projection for video communication on a user's mobile phone, the privacy of 360° displayed holographic images will be affected. [0005] Among the existing methods of privacy protection for holographic images, if they are directly blocked by hardware fences, the 360° panoramic experience will be poor; through software image processing, some privacy points are blocked or coded,...
