Brief introduction of three-dimensional film

Using the difference of visual angles and the convergence function of human eyes, we can produce movies with three-dimensional effects. Appeared in 1922. When showing this film, two pictures are superimposed on the screen. Through the audience's special glasses or the radial semi-conical lens grating in front of the screen, the audience's left eye can see the picture taken from the left perspective, and the right eye can see the picture taken from the right perspective, and the stereoscopic image is synthesized through the convergence function of both eyes.

3D and 4D stereoscopic movies

3D Stereo Cinema-On the basis of ordinary projection of digital movies, in the production of film source, the left and right eyes of the film source are displayed in two ways, and two projectors are used to project relevant pictures for each channel. Through polarizing lens and polarizing lens, the left and right eyes of the film source are projected on the left and right eyeballs of the audience respectively, thus creating a three-dimensional on-the-spot effect.

3D cinemas are generally designed in the form of arc curtains, which has a stronger three-dimensional effect.

The equipment of 3D stereoscopic cinema is mainly composed of film source playback equipment, multi-channel fusion processing equipment, projector (number of left and right channels ×2), projection arc screen, polarizer, polarizing film, audio and other equipment.

4D Cinema-4D Cinema is relative to 3D Stereo Cinema, which is based on 3D Stereo Cinema and added with various special effects of the surrounding environment of the audience, and is called 4D. Environmental special effects generally refer to lightning simulation/rain simulation/snowfall simulation/smoke simulation/bubble simulation/water droplet falling/vibration/spray simulation/air injection/spray/leg sweeping/ear wind/ear sound/wind blowing and so on.

The equipment composition of 4D cinema is relatively complicated. On the basis of 3D stereo equipment, special effects auxiliary equipment such as special effects seats are added.

4D movie-This concept is very close to 4D movie, but the difference is vague. 4D dynamic cinema mainly emphasizes the word "dynamic", which is reflected in more freedom of seats and stronger dynamic effect, not just the simple bump and vibration effect of 4D cinema.

4D dynamic cinema needs professional dynamic seats.

Stereoscopic film analysis

People's left and right eyes look at the same object, and the eyes see different angles, so the images formed on the retina are not exactly the same. After the two images are synthesized by the brain, they can distinguish the front and back, the distance and the distance of the object, thus producing stereoscopic vision. The principle of stereoscopic film is that two cameras imitate the visual angle of human eyes and shoot at the same time, and two projectors project on the same screen at the same time for left and right eyes to watch, thus producing stereoscopic effect.

When shooting three-dimensional movies, it is necessary to put two camera brackets on a special tripod head with adjustable angle and shoot at a specific included angle. The synchronization of the two cameras is very important, because even a few tenths of a second error will make the left and right eyes feel uncoordinated; So be sure to hit the board when shooting, so that you can find the synchronization point when editing.

When showing a three-dimensional movie, two projectors are placed in a certain way, and two pictures are projected on the same screen point-to-point in a completely consistent and synchronous way. A polarizer should be added in front of the lens of each projector, one is a horizontal polarizer and the other is a vertical polarizer (or diagonally crossed), so that the screen will reflect different polarized light into the eyes of the audience. Viewers should also wear polarizers when watching movies, and the polarization direction of the left and right lenses must match the projector, so that the left and right eyes can filter out the unpolarized images and only see the corresponding polarized images, that is, the left eye can only see the images projected by the left machine and the right eye can only see the images projected by the right machine. After these pictures are synthesized by the brain, stereoscopic vision is produced.

A film that produces a three-dimensional effect when shown by using the characteristics of human eyes' different viewing angles and convergence function. Ordinary movies or photos are shot from a single perspective, and the images are all on the same plane. People can only produce a sense of space according to their own life experiences (such as proximity, distance, smallness, light and shade). A stereoscopic movie is composed of two pictures with different horizontal viewing angles, which are similar to human eyes. During the screening, the two pictures overlap on the screen to form a double image. Through special glasses or a semi-conical lens grating in front of the screen, the audience's left eye sees the picture taken from the left perspective, and the right eye sees the picture taken from the right perspective. Through the convergence function of the eyes, it is synthesized into a stereoscopic vision image. Some of the images seen by the audience seem to be hidden behind the scenes, while others come out of the box as if they are within reach, giving people an immersive sense of reality. Stereoscopic movies with radial semi-conical lens gratings in front of the screen are strictly limited by the location of the seating area in the audience hall, so the audience's head can't move casually, otherwise the stereoscopic effect will disappear, which makes the audience feel extremely inconvenient. Colored glasses and polarized glasses are widely used in stereoscopic movies watched with glasses. Color glasses method is to print two images taken from left and right perspectives on the same screen in red and cyan (or green) respectively to make film. General projection equipment can be used for projection, but the audience needs to wear a pair of red glasses and another pair of blue (or green) glasses. So that the eyes passing through the red lens can only see the red image, while the eyes passing through the cyan lens can only see the cyan image. The disadvantage of this method is that the audience's eyes are unbalanced and easy to get tired; The advantage is that there is no need to replace the projection equipment. This method is often used in early three-dimensional movies. 1985 Tsukuba International Science and Technology Expo in Japan exhibited a black-and-white film in this way, and the effect was better. Stereoscopic film with polarized glasses has been paid attention to by many countries since 1922. Some countries combine it with movies with large vision to produce color stereoscopic films with higher quality and better effect. When this film is shown, the left and right pictures are projected on a metal screen with a polarization axis of 90 degrees, which will not destroy the polarization direction and become overlapping ghosts. When watching, the audience wears polarized glasses with a polarization axis of 90 degrees and corresponding to the polarized light of the projected picture, so that the ghost can be separated and a stereoscopic effect can be obtained. Due to the different production and projection techniques, polarized stereoscopic movies can be divided into two machines and single machine. 1985 Tsukuba Expo exhibits 70mm large-screen color stereoscopic movies. Since 1960s, China's stereoscopic films have been polarized stereoscopic films.

In the 1970s, the Soviet Union experimented with holographic stereoscopic movies, with a wide range of image brightness without glasses. Because the visual adjustment and convergence of the audience's eyes are natural, it will not cause excessive tension and fatigue. As long as the audience turns their heads, they can see the position change like the real thing, which is more profound than ordinary movies, just like the real thing. This kind of film is still in the experimental stage.

Stereoscopic film and polarization

Have you ever seen a three-dimensional movie? Do you know the truth about it? This is an example of polarization with light. When watching a three-dimensional movie, the audience should wear a pair of special glasses, which are polarizers whose vibration transmission directions are perpendicular to each other. In this way, the scene seen from the screen is three-dimensional. If you don't wear these glasses, the image on the screen will be blurred. Why is this?

This should start with people looking at things. Observing an object with two eyes at the same time can not only broaden the field of vision, but also judge the distance of the object and produce a three-dimensional sense. This is because when two eyes observe an object at the same time, the images formed on the retina are not exactly the same. The left eye sees the left side of the object more, and the right eye sees the right side of the object more. These two images can be synthesized by the brain to distinguish the front and back, far and near, far and near of the object, thus producing stereoscopic vision.

Three-dimensional movies are composed of two lenses, such as human eyes, shooting scenes from two different directions at the same time. During screening, two groups of films shot by two cameras are simultaneously screened by two projectors, so that two slightly different images overlap on the screen. At this time, if you look directly with your eyes, the picture you see is blurred. To see stereoscopic movies, a polarizer must be installed in front of each movie machine, and the role of the polarizer is to play the role of a polarizer. The light emitted from the two projectors passes through the polarizer and becomes polarized light. The polarization directions of the polarizers in front of the left projector and the right projector are perpendicular to each other, so the polarization directions of the two polarized lights are also perpendicular to each other. These two beams of polarized light are projected on the screen and then reflected to the audience, and the direction of polarized light remains unchanged. When the audience watches with the polarized glasses, each eye can only see the corresponding polarized light image, that is, the left eye can only see the picture reflected by the left machine, and the right eye can only see the picture reflected by the right machine, thus creating a stereoscopic impression like direct viewing. This is the principle of three-dimensional movies.

Of course, the actual projection of three-dimensional movies is to use one lens, and two groups of images are alternately printed on the same film, which requires complex devices. It's not involved here.

Three-dimensional film photos

Three-dimensional film photos are multi-lens digital records of people, scenery or products with a 360-degree stereo camera independently developed, and then processed by stereo equipment. Three-dimensional photo has a three-dimensional real effect like a three-dimensional movie, and it is the most fashionable image consumption mode in the aristocratic field of developed countries in Europe and America. The distance between photos and images is different, the layers are distinct, and the vivid three-dimensional sense of characters is vividly presented, giving people a brand-new visual experience of traveling in the illustrated world. You can see the wonderful pictures of different pictures from different angles, and you can design and make visual effects such as animation rotation, scaling and change!

Three-dimensional film photos can be applied to artistic portrait photography, personalized wedding photography, fashion children photography, pet baby photography, commercial product photography, interior decoration photography, three-dimensional display of architectural sculpture, tourism landscape photography and so on.

Stereo movie home theater

Play a stereoscopic movie with a PC, then put on special glasses, and use the parallax between the left and right eyes to see a stereoscopic image. Playing stereo video games with advanced audio-visual system is really a brand-new enjoyment.

You must have heard of the term "three-dimensional movie", and you must have a chance to see it. Maybe you even have some products related to it at home. The term stereoscopic film is a bit narrow, limited to "movies with stereoscopic effect". Suppose we enlarge the definition a little and change "stereoscopic film" into "stereoscopic image". Is this much broader?

Stereo images, as the name implies, are three-dimensional images, and I don't need to say more. As long as you open your eyes, you see a three-dimensional image. It's just that I usually look at things with my eyes, and I'm not surprised by the three-dimensional sense. No one will be happy because I open my eyes and see a three-dimensional image. However, if we close one eye when looking at something, we will immediately find a phenomenon, that is, the image remains unchanged, but our judgment on the distance of the object is still half. Try to reach for something, and you may not be able to locate it accurately at this time.

Yes, under normal circumstances, all the video programs we see are flat and have no real depth of field. Seeing an image with one eye or a pair of eyes won't have any feeling of distance, but wouldn't it be novel if we had the opportunity to see an image with three-dimensional effect through the screen of a home theater today? The users of this interview have such a set of equipment for "making" stereoscopic images at home. Through stereoscopic glasses and three-gun projectors, they can easily feel the stereoscopic image of sitting on the sofa, and the characters in the image will interact with the environment in three dimensions, just like being in the scene.
