Terminology of scientific and technological imaging
Phantom imaging is an imaging technology based on holographic technologyHolographic imageIt is projected onto transparent media to produce 3D stereoscopic impression and improve visual effect.
Phantom imaging system is also calledVirtual imagingIt is based on the combination of "real modeling" and "phantom" optical imaging, and projects the captured images (people and objects) into the main model landscape in the set box to demonstrate the development process of the story.It is vivid, illusory, and very intuitive, leaving a deep impression.From stereo model scene, modeling light system, optical imaging system (applicationPhantom imaging filmAs an imaging medium), film and television broadcast system, computer multimedia system, audio system and control system, it can realize realistic display of large scenes, complex production lines, large products, etc.
[History of Phantom Imaging]
Phantom imaging effect
In the 1990s, phantom imaging technology was first used in museums and other public places in some developed countries.
[Phantom imaging hardware device]
In the past year or two, some domestic museums have also begun to introduce foreign advanced technology, using phantom imaging technology to tell the public the stories behind cultural relics.The phantom imaging display system is mainly composed of hardware and software such as physical display platform (also called physical model), projector or other display equipment, 3D special effect video, phantom imaging film, hydraulic and mechanical control equipment.
Phantom imaging film principle, the surface of the film passes through vacuumMagnetron sputtering coatingNanometer photosensitive coating is prepared by the process, so that the film maintains a high transmittance of 99.99% and also has a high reflectivity (mirror appearance).The main component of the film is SOBPhotosensitive material）It has delicate imaging and high definition imaging function, which can make the image produce great stereoscopic depth.[1]
[Advantages of Phantom Imaging]
The advantage of phantom imaging is that its imaging is realistic, and the three-dimensional special effects are very dazzling. It can achieve the effect of confusing the real with the fake without wearing 3D glasses.Phantom imaging technology has been widely used abroad, and gradually applied in various domestic museums, celebrities' former residences, century old towns, historic streets, theme parks, heritage parks, urban planning exhibition halls, etc.

working process
Holography in science fiction movies[2]
The main model scene of the phantom imaging system creates environment space for optical imaging.Modeling lighting system Optical imaging system and film and television broadcast system complete the reproduction of active three-dimensional video in the scene modeling, so that the three-dimensional image has a relatively "real" combination with the surrounding artificial landscape background.The sound system plays narration and music;The control system completes multi machine synchronous control, active model control, light control, power control, playback control, etc. It is processed by a computer, made into a disc, and operated by a controller. The staff can complete the whole process by pressing the switch.
Through computer film and television post production technology, editing and splicing, you can use a small space to obtain a large amount of information, spanning time and space, and covering a wider range.It is beneficial to show the story content and improve the audience's interest in visiting.
Viewing size
Phantom imaging system is usually designed as a single scene or four scenes, with a viewing screen width of 1.0m-10m;The scene height is 2m - 2.5m;The scene depth is 2.0m - 3.0m;The height of the character image is 0.4m-1.80m.
Design features
The "imaging depth control technology" can realize the sense of depth and space of the phantom imaging picture, so that the image and the background scene can be perfectly integrated.
At the same time, it also has the following advantages:
The height of the character can be 50 cm - 180 cm (the image height of the character can be adjusted according to the user's needs);The facial features of the character picture are clear, the skin color is restored correctly, and the hair is clearly visible;Continuous gray scale, good sense of visual hierarchy, strong sense of three-dimensional;There is no zigzag, no border, no flicker, and the color is soft and natural;The background props can be arranged according to the real spatial position, so that a variety of visual elements can be displayed in the real environment according to the perspective relationship of the real spatial position relationship. The visual content is rich, and the scene has strong stereoscopic sense.The background light effect can be set arbitrarily, and the picture has a strong sense of hierarchy and depth.
For large amusement parks
The "Magic Theater" realized by the phantom imaging technology is a large-scale indoor theme publicity form, and the Magic Theater is also known as the "Phantom Performance Theater".The project uses illusion imaging technology, computer synthesis technology, optical reflection principle, etc. to make the stage real scene objects and video reflection objects complete the theater form of performance together. In the theater system with live performance and real stage, it can achieve very strange, unique, and unthinkable performance effects, suitable for representing various surreal styles of theme content.For example, performers can suddenly appear and disappear without leaving traces on the stage;It can make flames and smoke change into various magical images, sometimes into cute birds, sometimes into dancing crowds;It can make a real person suddenly become a bird and so on.
1. Performance effect
The "phantom imaging" used by Magic Theater is a kind of video technology, which has a strong sense of depth and is difficult to distinguish between true and false. Its advantages lie in its novel imaging method, strong visual effect and strong three-dimensional sense of image.The image suspended in the air is sometimes close to your eyes, giving you a feeling of reaching out;Sometimes, it will bring people's vision to the distant star sky, sometimes far or near, sometimes bright or dark, unpredictable.Those spiritual flames are formed above the campfire by using the "phantom imaging" technology. They are suspended in the air and have a unique feeling of emptiness.
The Magic Theater makes full use of "phantom imaging" technology, and integrates digital image production, stage optical systemcomputer control system , achieving a stunning stage effect.The program uses two sets of stages, and then through the principle of optical reflection and careful debugging, it shows the audience magical effects, such as the emergence and disappearance of actors, and fireworks changing birds fall on the hands of actors, which not only realizes the common performance effect of images and stage actors, but also uses optical images to achieve the emergence and disappearance of stage actors,The magic effect will open the audience's eyes.
The stage lighting achieves a perfect visual experience and is pleasing to the eye.Although the program uses a variety of technical means, the visual effect is very unified, the color and light are in harmony, the picture is beautiful and pleasing, the rhythm is ups and downs, the use of stage lights is very sophisticated, especially the lights with fireworks include lightning, starlight, bonfire jumping, smoke rising, and the varied lighting effects add color to the whole program.
2. Theme
Prometheus Space Travel Hibernation[2]
The Phantom Performance Theater is a large performance theater with live performances. It is suitable for representing various surreal themes, such as myths, legends, inferences, science fiction, historical reproduction, macro things, micro things, etc. It is suitable for use in science and technology museums, museums, exhibition halls, theme parks and other places.
In the magic theater, the digital video production technology has shown its skills.For example, one of the interesting and special attractions of the magic theater program is the bonfire with spirituality. When the old man recalls his life, the bonfire will change various images with his narration. These are the effects made by digital technology, and the fire is shaped into the shape required for various programs by 3D animation production tools,It also gives smart movements. When the flame turns into a lively girl or lovely child, the audience will be attracted by it.
