Application scenarios of digital sand table in various industries:
1. Real estate exhibition hall: On the basis of traditional solid sand table, various multimedia acousto-optic technologies based on dynamic projection have been added, breaking people's stereotype of monotony of sand table. For the real estate exhibition hall, the sand table is indispensable. In this era of serious information surplus, we need the sand table to show a new face, so as to attract more audience's attention and increase the number of potential consumers. Through rigorous design, the multimedia projection sand table realizes multi-functional synchronous linkage, and uses LED lighting, dynamic projection video, large arc screen and other sub equipment of the sand table to show the best side of the building vividly.
2. Urban planning museum: digital sand table is a revolutionary innovation. On the basis of traditional solid sand table, various multimedia acousto-optic means based on dynamic projection have been added, breaking people's stereotype of monotonous sand table. In the urban planning museum, the sand table is the most indispensable. The sand table is a miniature of a city, providing the audience with a bird's eye view of the city and the overall situation. However, the traditional sand table model can only represent the city in a time dimension, which is far from enough for a city planning that lasts for several years or even decades. Through rigorous design, the multimedia projection sand table can realize multi-functional synchronous linkage, call the sand table LED light, dynamic projection video, large arc screen and other sub equipment, dynamically show the past, present and future of a city, and jump and change in different time dimensions. It is the best tool to explain a city's planning.
3. Military application: digital sand table is one of the indispensable equipment for military command and operation. The traditional paper map shows various kinds of information that are relatively abstract, and the commander will make mistakes or omissions if he is slightly negligent, which will affect the combat effect. Our company recommends setting up battle sand tables in major command places, and simulating the display of mountains, rivers, roads and bridges on the sand tables, so that the military personnel can better understand the local terrain and make the battle plans of all commanders and fighters more vivid and clear.
4. Traffic digital sand table
Traffic conditions have always been the top priority of people's attention. The complicated traffic routes and various road emergencies have brought many inconveniences to the command work of traffic staff. The digital sand table can present various road conditions to the headquarters in a timely manner, and the headquarters can actually see the scene through the digital sand table to conduct timely and effective visual command and management.
5. Museum
The digital sand table used in the museum and exhibition hall can combine multimedia images, holographic projection, VR technology, AR technology and 3D technology, so that visitors can interact with equipment through touch screens, mobile phones and other terminals, increase the interest of visitors, deepen their impression and increase their sense of experience.
6. Tourist attractions
The tourist attractions can use multimedia sand tables to comprehensively display the tourist routes, history and culture of the scenic spots, together with video, video, text and other information, so that tourists can quickly understand the history, culture and natural features of the scenic spots without the need for staff to explain.
Installation requirements and conditions for digital sand table interaction:
The important condition for the installation of digital sand table is the floor height. Here is an example to illustrate that, for the white model projection sand table, the floor height is normally 3 meters. Of course, the higher the height is, the higher the height is, generally 6-10 meters. Why 6-10 meters? Because the effective pixel projection ratio is 1.2-1.5:1 when a single projector reaches 3m, the effect is very good.
Another kind of white mold is hung on the wall. Generally, the floor height is 6-10 meters, or it can be 3 meters of ultra short focus. The short focus projection ratio within 3 meters is 0.6:1 and 0.8:1. Another thing to note is that the floor height cannot exceed 15 meters, which will affect the installation problem, and of course, can not achieve a good display effect.
In general, there are many problems to pay attention to in the installation of the sand table, and there is also the problem of light. If the ambient light is bright, the projection effect will be very poor, so a projector with high lumen will be required, depending on the situation of the project.
