Problems solved by technology
[0005] However, at present, the realization of holographic projection needs to be equipped with huge projection equipment, which is poor in mobility and convenience; moreover, the images projected by the existing holographic projection equipment are all 3D images preset in advance, and the 3D images have been recorded Object light wave information, but does not consider the impact of reflection and refraction of various materials in the background environment on the holographic image. For example, the light source in the background environment is reflected and refracted by various materials, and the brightness, shadow area, The color has a certain influence, so the fidelity of the 3D image preset in advance will be greatly reduced

Embodiments of the present disclosure provide a holographic projection device and method. Among them, several holographic films are set up around the projection body, several display screens of the projection terminal face inward and are arranged around several holographic films, and each display screen corresponds to a holographic film; the camera of the projection terminal is used to take images of the background environment and Send it to the server, so that the server takes out the information of the marked object in the background environment, and then performs global illumination compensation on the original 3D image data according to the information of the marked object to obtain the global illumination compensation image data; the processor of the projection terminal is also used to convert the original The 3D image data and the global illumination compensation image data are respectively sent to different display screens for imaging; several holographic films are used to project the images displayed on their corresponding display screens to be superimposed into a final 3D image. The device described in the embodiment of the present disclosure has small volume, good mobility and portability, and also improves the fidelity of the 3D image finally formed on the projection background.
Description
technical field [0001] The present disclosure relates to the technical field of projection devices, and in particular, to a holographic projection device and a holographic projection method. Background technique [0002] Holographic projection technology (front-projected holographic display), also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional images of objects. [0003] The first step is to use the interference principle to record the light wave information of the object, which is the shooting process: the object to be photographed forms a diffuse object beam under a part of the laser irradiation; Superposition produces interference, which converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, thereby using the contrast and interval between the interference fringes to record all the information of the object l...
