9 d dynamic seat an overview of the development and technology
one, the history of 4 d motion seat.
in the 1990 s, the Japanese have appeared in the wind and rain lightning effects, and the 4 d movie theater seats will move, but this kind of 4 d movie also have not been able to popularity. This technology in China at the 2008 Shanghai world expo, caused great reflection.
really commercialise motion seat is D - the United States BOX company, their Hollywood debut in April 2009, and six major Hollywood film only authorized signing together 4 d film production company. After their seats in the Canada, Britain, Japan, the Netherlands, Germany, they probably entered China in 2012. 2009 universal 'speed and passion' is the first by a D - BOX provides code film, now Paul & middot; Walker, unfortunately because of car accident died, and D - The BOX is not very well in China.
CJ group company is a business culture, they began in 2010 in South Korea to build 4 d cinema, almost become the pronoun of the 4 d cinema. They entered into China is also very successful, open a dozen with IMAX and 4 d theaters screens. Then came the domestic some like fuhua intelligent technology of 4 d motion seat manufacturers. Fuhua intelligent technology will these 4 d motion seat, applied to small theaters, the 4 d cinema screens, as well as the reform of the old movie screens. These domestic 4 d dynamic screens, also very attractive to the audience, animating the whole movie box office.
D - BOX dynamic seat is alone, there is a certain distance between each seat. With D - BOX, fuhua intelligent production of science and technology, the dynamic seat is usually two a group, or triplet, they also recently developed quaternion, a group of five seats. These 4D motion seat number, the biggest advantage is to save space, costs have dropped too.
2, 4 d motion seat movement.
at present, the domestic many of the 4 d cinema seats, not dynamic seat. With vibration, blowing, water spray, ErFeng, legs and other special effects, these elements as one element of the 3D movie outside, also known as an element, and became the cinema 4 d.
really, the 4 d motion seat is below it support the three electric pole. The three root electric pole is driven by servo motor, electric cylinder can be moved up and down. The three root electric cylinder is three degrees of freedom simulation platform, D - BOX company first is to apply them to the United States air force aviation institute of aviation flight simulators. This three degrees of freedom simulation platform, can simulate seemed as falling, bumps, dangling tumbling movement. The audience can feel driving, flying, running in the seat, explosion, the impact of the wave, turning and shooting scene. Audience before the lifelike, the three-dimensional images of be vividly portrayed, can be thrilling and exciting adventure, ground may frighten the soul fly up, may also be thrilled. The audience's sense of touch and balance will be comprehensive stimulus, will be put into the movie, think oneself became a character in the film.
in cinema 4 d motion seat movement range is shoulds not be too big. Because different from science and technology museum and 7D cinema, science and technology museum and 7D cinema movie time is shorter, required movement range is bigger, the better, people just feel exciting. But in the 4 d cinema, blockbuster time is usually up to 2 hours. And it has a very long movie action scenes, continuous action scenes. Audience in such a long time, sitting on a dynamic seat seemed as swing, the body will be uncomfortable.
some dynamic seat is powered by air or hydraulic oil, but these seats in the cinema construction needs under the seat arrangement of many of the trachea and tubing, very trouble. Three degrees of freedom simulation device and servo electric cylinder type, just under the seat cloth good power line and control line can, for the installation of seats is very convenient.
three, dynamic control and production.
4 d cinema effects and seat in the movement, as well as the action, action of the length of time, is composed of a computer, plus a movie broadcast system control. As a result of the film is stereo and large images, it takes two to eight single projector, then insert the image fusion. Most movie player, need can control eight single projector. Fuhua intelligent technology independent research and development of the movie player, besides can eight single projector, can also expand effects control port, in order to increase the specific equipment.
movie broadcast control system for special equipment and seats, is done by action code [ 2] 。 The action code is action programming, according to the action in the film and the scene to write. After writing code, can be stored in a computer. When the film screening, the movie player control 4 d motion seat as the film content synchronization action.
4 d motion seat is composed of three degrees of freedom platform, seat surface, back of a chair, armrest, coating materials, to produce the 4 d motion seat is not very difficult, there are many domestic manufacturers can do now. But the action code is difficult, perhaps only now CJ and domestic fuhua intelligent technology can make the original code. Action code, is like a 3D film post-production. According to the content of the film editing special equipment and dynamic seats, when action, action range and action time.
