CCTV5 "Magnificent Feast" in the interpretation of the 2010 World Cup, the program site to show the virtual technology synthesized 3D South Africa World Cup stadiums, but also with the change of the camera changes in perspective and depth of the change, the 3D effect is great, a lot of people interested in the technology, the number of Tiger Imaging Technology technology Department for you to explain these technologies.
World Cup 3D holographic projection OR augmented reality technology dispute
Although many people are impressed by the effect of the 3D stadium, but do not know how he was formed, there are currently many people understand him as a 3D holographic projection technology to achieve, meaning the use of the principle of holographic projection to generate 3D image effects on the stage, because they feel that holographic technology is a very popular recent technology, science and technology museums and museums, even the Shanghai World Expo have used holographic projection technology, so such an effect of realistic effects, certainly also holographic projection undoubtedly.
And the other part of the people think it is virtual reality in augmented reality technology, it is through the motion capture, through the image and geometric model of the seamless combination of real and virtual fusion. According to the feast 3D stadium scene environment and imaging characteristics, initially determined that it is not holographic projection imaging, but augmented reality technology virtual imaging.CCTV5 "feast" in the interpretation of the 2010 World Cup, the program suddenly appeared in the live broadcast of augmented reality technology synthesized 3D South Africa World Cup stadiums, but also with the change of the camera to change the perspective and depth of change, really exciting for the audience. It really made the audience excited, augmented reality technology undoubtedly for this summer added a few breath of science and technology, in the people's discussion of the World Cup game at the same time, there is another topic of conversation.
Augmented Reality Scene Analysis in Magnificent Feast:
So how is this augmented reality virtual 3D South Africa World Cup stadium realized? The next number of tiger images will be for you to analyze one by one. In this virtual 3D stadium they are through the use of QR code class markers to locate, the camera captures the markers image by the software to calculate the content to realize. At least the following basic hardware was used in the broadcast:
1. mark -- for image recognition
(markers for image recognition)
2. camera to capture the marker pattern (I'm guessing the camera was right above the markers)
3. computer (even better with a projector screen) )
The camera takes a picture of the real scene and records its position and orientation in real time by capturing the marker through computer vision technology, superimposing a virtual 3D object onto that position to form a fusion of reality and reality. This is the kind of scene you see in front of the TV, in fact, this technology also has a small drawback, that is, the audience on the scene can not see this virtual scene (if you have seen the CCTV weather forecast is how to record, you probably understand this technology, but this technology is much more advanced than the CCTV weather forecast). We can see the breakthroughs at a glance by watching the video: Augmented Reality in the Magnificent Feast The scene is as follows
(the scene of the fusion of the virtual and the real, the application of augmented reality technology to show that the stadium in the middle of the map is virtual)
(a small break, Zhang Bin accidentally walked behind the virtual scene)
The audience, including the hosts, Zhang Bin and Tong Kexin, can not be seen on the scene, and they can see it only on the output TV signal. The output of the TV signal can be seen, because the middle of the 3D stadium is virtual, Zhang Bin can not see, so inadvertently he went behind this virtual stadium.
