Holographic three-D image recording and display method and its device and application

Abstract

The invention provides a method and device for recording and displaying holographical three-dimension image. It uses shooting device to shoot scene continuously in movement, acquires two-dimension image with different perspective structure, and transmits them into computer through interface; it also can use three-dimension model image processed by computer to gather two-dimension image of each look angle; the acquired serial two-dimension images are displayed by the displaying device under process and control of the computer, as the target of holographical record; each two-dimension image displayed by the liquid crystal displaying device is recorded into a narrow stripe of the holographical negative film in order, as the unit holographical image, all the serial two-dimension images are recorded onto the whole holographical negative film, as the holographical mother board; the penetrating or reflecting holographical image can be produced with the holographical mother board; the holographical image can be reduced into three-dimension stereo image radiated by laser or white light.

[0002] Holographic stereo imaging technology is an emerging technology, and its related products are gradually being widely used in real life, such as anti-counterfeiting marks, ID cards, credit cards, cigarettes, wine and other industrial products such as sealing labels and packaging technologies field, the holographic stereoscopic image formed by holographic stereoscopic imaging technology, under the illumination of a specific angle and natural light source, its diffraction image can present changing brilliant colors in the front and rear spaces of the image plane, thereby producing a visual stereoscopic effect; for example, the application number is 01128022.0 The Chinese invention patent application disclosed a "method for making a dynamic laser holographic three-dimensional light column". Hologram, and then use the main hologram to shoot the photoresist plate, and finally process the photoresist plate to get the hologram. This hologram just adds a beam of light to the anti-counterfeiting mark, that is, adds a password that can be recognized by the naked eye; and This production method is limited to processing graphics simulated by computer, and it is inconvenient to process images formed by actual objects, especially synthetic images formed by continuous shooting.

At present, the technology of processing actual objects to form holograms generally uses smaller real objects or transparent sheets as the recorded objects, and shoots them directly on the holographic platform. This processing technology also has great limitations, such as making portraits. The holographic three-dimensional image encounters difficulties, because it is not possible to put a living person on the production platform and irradiate it with laser light. In addition, also can not handle for bigger object or scenery; If take out transparent film and synthesize again with film camera, process is very troublesome, and cost is expensive, is unfavorable for large-scale popularization and application on the industry, so for large object, location, character , Computer-designed virtual objects and other objects that are not easy or cannot be moved to the holographic table for shooting and processing, so as to form a hologram technology research has important practical significance
