In the upcoming Spring Festival Evening of 2013, what technical equipment will be used in the stage visual effects to complete the new ideas of the Year of the Snake? It has been reported in the news that in the Spring Festival Evening of the Year of the Snake in 2013, the stage equipment will not be replaced in large numbers, and it will only be played on the equipment of last spring and evening. It can be seen that a large number of LED splicing displays are still the main equipment for the colorful background of the 2013 Spring Festival Evening stage.
In the Spring Festival Evening of 2012, the 8,000-square-meter LED display unit was used to create the world's largest indoor visual effects unit. The stage floor, ceiling, side and stage background walls and decorative columns are equipped with LED color screens, in order to achieve a more three-dimensional stage display effect. At the same time, the stage is also equipped with 304 lifting platforms to facilitate flexible application of different programs.
The Year of the Dragon and the Spring Festival Evening, the realistic background effect, integrated with the program, presents a very stereoscopic 3D visual experience. In the Spring Festival Evening of 2013, let us look forward to what kind of creative display this 8,000 square meter LED splicing display can bring.
　　 LED display has the advantages:
1. Low cost and easy maintenance, strong and durable: In the large screen splicing display device, the LED display is relatively low in cost;
2, not affected by ambient light, easy to install: In the large-screen display device, except for the projection and splicing display, other devices are not affected by the ambient light; and the LED splicing screen is easier to realize the screen lifting and moving, which is convenient for the stage to change intelligently;
3, large screen splicing, in the splicing display, projection splicing and LED splicing display can be extended infinitely, but the projection spell receives a large impact on the ambient light, LED splicing is a good choice in the stage effect of the Spring Festival Evening. Although there are LED particles, the large display screen can completely ignore the graininess in the display.
In the 2012 Spring Festival Evening stage, everyone mistakenly thought that the holographic three-dimensional display of "Because of Love" and "Wanwusheng" scene effects, in fact, there are no petals falling on the scene, there is no holographic image of plants, but through AR augmented reality technology, in the program A virtual scene added in real time during live broadcast. AR augmented reality technology is a virtual environment that uses a computer to generate a realistic sense of sight, sound, force, touch and movement. Through various sensing devices, users are immersed in the environment to realize direct natural interaction between the user and the environment. . This technology is widely used in broadcasting and broadcasting.
Augmented reality is a new kind of human-computer interaction technology. It can simulate the real scene landscape with such a technology. It is a computer advanced human-machine interface based on interaction and conception. Through the virtual reality system, you can feel the immersive realism experienced in the objective physical world. Of course, in order to produce such realistic three-dimensional effects, in addition to the cooperation of technology and hardware devices, you need to have stereo high-definition background display content. stand by.
The characteristics of AR technology mainly include two aspects:
1. AR technology can synthesize and transmit real scenes and virtual images, such as naked-eye 3D effects.
2, AR technology, can achieve virtual image and real-time synchronous communication, live broadcast in the Spring Festival Evening in 2012, the stereoscopic effect seen by the audience in front of the TV is achieved through this technology. The original LCD splicing screen can provide high-definition image quality output, compared with the LED splicing screen, reducing the particle point of the screen display, showing the original clear effect of the picture. Although the cost of LCD splicing screen is slightly higher than that of LED, it can also achieve mobile splicing control, provide more flexible background display for stage effects, and provide higher definition image quality.
LCD splicing can be used as a display alone or as a large screen. According to different application environments, the corresponding solutions can be built, and the application is relatively flexible. In the 2013 Spring Festival Evening stage, you can provide background support for essays or other creative performances.
The application of LCD splicing screen is now ultra-narrow LCD splicing screen, the largest unit size is 60 inches. On the CCTV Spring Festival Evening stage, it is not impossible to splicing more than 100 square meters of display wall, and the LCD splicing display wall can provide high-definition presentation screen. .
The 2012 Spring Festival Evening "The Legend of New Year's Eve" program, the vivid and novel expressions attracted the attention of many viewers, and also aroused many children to pay attention to the Spring Festival Evening. Innovative programming, coupled with the large-screen interactive projection effect, adds a lot of legend to this show. On the stage of the Spring Festival Evening in 2013, the application of projection and splicing display will still be based on the background of individual programs.
The projection splicing display can achieve a true seamless splicing effect, but it is affected by the ambient light, and it is necessary to close most of the lights in the Spring Festival Evening to display a beautiful picture. In addition, the installation of the equipment is fixed, non-movable, and the display on the stage is not flexible enough, so the application of the projection splicing display in the Spring Festival Evening in 2013 will not be too much, and on the CCTV Spring Festival Gala program that is exposed by the media, the author does not have I feel which program can be applied to the projection mosaic display scheme.
Galvanized Steel Pipe divided into cold galvanized Steel Pipe, hot dip galvanized steel pipe.Galvanized steel pipe surface has hot-dip galvanized layer or electric galvanized layer.Hot galvanized pipe is molten metal and the iron matrix reacting alloy layer, so that the substrate and coating combination of both. Hot-dip galvanizing is the first steel pickling, in order to remove the steel surface of the iron oxide, after pickling, a mixed aqueous solution tank cleaning by aqueous ammonium chloride or zinc chloride or ammonium chloride and zinc chloride, and then into hot-dip plating bath. HDG has a uniform coating, strong adhesion, long life and other advantages.
