What is water curtain movie? What is the principle?
What is water curtain movie? Waterscreen film technology is a kind of multimedia technology that a beam of light illuminates the surface of the water and displays a strong stereoscopic film effect. People who have seen the water curtain movie feel very shocked. Do you want to know what the principle of water screen movie is?
What is water curtain movie?
Water curtain movies are made by high-pressure water pumps and special water curtain generators, which eject water from bottom to top at high speed and form fan-shaped after atomization. When viewers watch the movie, the fan-shaped water curtain merges with the natural night sky. When the characters enter the picture, it is as if the characters take off to the sky or descend from the sky, producing a kind of illusion and illusion, fascinating. The water screen projector consists of mechanical device, control bracket, communication port, software, time signal interface and DMX512 interface. The projector engine is controlled by optical sensor with high precision. There are three control methods: programming control, direct control and practical program control. The water curtain is up to 20 meters high and 30-50 meters wide. All kinds of VCD discs or water curtain special films can be played on the water curtain. The film and television effects are strange, novel and excellent advertising tools. Water curtain movies can be installed on all kinds of square and open water surface.
Water curtain is usually as high as 20 meters, 30-60 meters wide, the screen when playing water curtain movies has a strong sense of three-dimensional and space, characters like flying from the sky or falling from the sky, and the natural night sky into one, resulting in a vague and dreamy feeling, coupled with laser patterns, the scene is even more grand, momentum. Water curtain films are suitable for major festivals, large squares and theme parks.
Advantages of water curtain films
1, the picture is huge.
Generally small water curtain, length and width are close to 10 meters, an area of about 100 square meters; large lake water curtain, length can exceed 150 meters, height can reach more than 30 meters, its night long-term effect than the city's landmark buildings more distinct. The water curtain can also be adapted to local conditions, such as local waterfalls and other facilities. The characteristic of super large water screen is incomparable with other technologies.
2, various forms
Simpler and useful pool plane, there are rectangular vertical plane, there are irregular vertical plane, there are 360 degree circular three-dimensional. In early 2011, the circular water curtain film was officially launched in Hongkong's Ocean Park.
3, the visual impact of shock.
With super high-power sound effects, unpredictable laser beams, like a mirage of the general scene, so that the audience near the scene feel mysterious Wonderland general.
4, wide audience
Not only can we watch closely, but we can also go far. Of course, viewing from different angles can have different effects, such as watching by the lake, high-rise nearby, in the distance or aerial photography, etc. Anyway, there is always a free way to watch a water screen movie.
Disadvantages of water curtain films
1, the cost is too high.
Small vertical water curtain may be the least cost, but the imaging range is too small. The largest of Singapore's fixed water screen landscape films is reported to have invested more than 1.300 million Singapore dollars; irregular domestic, medium-sized water curtain landscape, generally invested more than 20 million yuan; large-scale, single, laser effect of the water curtain performance, it is known that the investment is also more than 10 million yuan. When the water curtain works, the electricity, water, site and personnel costs are like burning money, and the maintenance costs are very high.
2. Site restrictions
It can only be held in very open space, outdoor areas, pools, lakes, riversides, riversides, seaside, or plazas that provide excellent water supply and drainage systems.
3, time constraints
The season and climate are very influential. Winter in the North certainly won't work; usually in summer, or in tropical areas such as Hong Kong, Macao, Guangzhou and so on, it can be performed all year round. Some weather changes, such as heavy rain, fog, gale, thunder and lightning, hail and so on, can also have an unpredictable impact on water screen movies.
4, technical constraints
Many hardware devices need to be imported, and there are many technical limitations. Taking the three-dimensional plane water curtain as an example, the spraying height from bottom to top is limited due to the limited power of the ultra-high pressure water pump; the dynamic picture such as huge picture, playing video and so on, which requires high brightness of large-scale projectors; the ultra-long and ultra-wide picture, mosaic and fusion technology, and so on.
5, rough picture effect
As a result of the width of the reasons, the brightness of the light is not high, water medium uneven and other reasons, water curtain generally only look at the macro scene, not demanding details. To put it simply, it is to see the painting. Don't pick it out.
What is the principle of water curtain film?
The principle of water screen film design is to use high-pressure water pump and special water curtain generator to eject water from top to bottom at high speed, thus forming a fan-shaped Mist & ldquo; screen & rdquo;. Then, a special projector is used to screen the movie. When people watch the water screen movies, the fan-shaped screen and the natural night sky into one, when the characters in the film enter the screen, it seems like the real, people have a kind of illusion and illusion.
This kind of projector is mainly projected by optical sensing control. This control method can be realized in three ways, including programming control, direct control and practical program control. Waterscreen movies can be designed as high as 20 meters, wide in 30-50 meters or so, the effect is novel, is a good tool for advertising.
