Network of Olympic flame

Here, the new computer magazine reporters will take you to the "virtual Olympic Museum", with the sharing what he has seen, heard and felt in everything.

Original publication in the new computer "

More lifelike than reality

Due to technology restrictions, the early Virtual Museum there is a similar problem, that is, all information are two-dimensional performance.

Although a small number of families joined the sound, video and other multimedia content, but generally speaking, the vast majority of the Virtual Museum is also just a static information platform, the lack of interactivity, unable to make the visitors have the feeling of being there. However, from Microsoft Research Asia and Beihang University School of computer science cooperative research and development of the "Virtual Museum" is unique for the Olympic Games. For designers, this would be a "true stereo of the Museum, visitors will feel like the real Museum even more realistic feeling. ”

"Virtual Olympic Museum" project is one of the most important results of the research and development by Microsoft Research Asia real-time interactive "multi-view video system" technology.

This technology sounds very complicated, but the content of their realization has already well known, that is the movie "the Matrix, the matrix that Nouri · Levi's vacated 360 ° Omni-directional camera. But, this scene in the movie is static, the audience can only see the protagonist of the scene for a moment. In the application of new technology, because the scene a number of cameras, and these cameras also are coordinated through the computer, being able to sync to shoot, so that we can play the entire video, arbitrary choice of interest perspective. Technically, interactive multi-rater video is not only a new type of video capture system and method, it is a new interactive video services technologies from multiple perspectives. This system includes a video camera, control, computer, server, network components, and the client. In order to realize the whole process of omnidirectional shooting, we will be filming on-site layout dozens to hundreds of video cameras, the camera calibrated and controlled by computer. In the photograph, the event will be a different orientation of the camera also captures the full video will be in control of the computer and real-time compression to the server, or to be transmitted in real time to the end user, the user can get any point of the video image.

"Real-time interactive multi-rater video system" can not only provide the user with multi-angle movie, most interestingly, from the perspective of the switch can also be controlled by the users themselves.

We can imagine that if every game of the Olympic Games will use the system for recording and playback in real time on the network, then we will have an unprecedented visual experience. We can watch the game from any angle, we can better than live audience to see more things we can see the past difficult to appreciate the various classical scene.

Museums: the true history

As a Museum, one of the most important responsibilities is to preserve the original appearance of historical information, these historical data are not complete, and accurate and, where necessary, it can even restore through these materials from the historical truth.

For "virtual Olympic Museum", because it is completely based on digital technology, so the data is saved in a unique position: they saved data from a time damage.

In the virtual Olympic Museum, the small art statue, sports equipment, the large to the entire Stadium, can realistically reproduced in people's eyes.

And this, thanks to technical staff of the 3D laser scanner. The scanner works is simple: as the laser's speed is constant, therefore, as long as we know the issue and return of the light beam, it can calculate the distance between them. As long as we can get a three-dimensional objects on a sufficient number of points and the distance between the emission source, naturally you can obtain accurate information about its appearance, it can generate its 3-d computer model.

Of course, to obtain perfect scan results and not be so easy.

Because the scanning of only a few of the point cloud data,To make the appropriate treatment to construct a realistic 3D model. In this process, people may encounter various problems. In "virtual Olympic Museum", staff with 3D scanning technology has developed a kneeling shoot color in ancient China terracotta figures of the three-dimensional model. In the use of multiple angle scanning gets enough data, technical personnel developed appropriate software for data restoration, multiple data blocks of the automatic splicing, model since Eclipse generation model vulnerability remediation, as well as high resolution texture mapped automatically, and so on, the computer generates a shown identical realistic 3-d model. Three-dimensional laser scanning technology, the "virtual Olympic Museum" technician will construct a large number of, and Olympic-related lifelike 3D models, such as sports art, large gymnasium and the ruins of the ancient games. In this way, people don't come to appreciate them.

Olympic spirit: participate

"Virtual Olympic Museum" and ordinary compared to maximum online Museum of unique feature has a great deal you can let users participate in the content.

The "Virtual Museum" includes the Olympic Games, Beijing Olympics, the modern Olympic Games, ancient Greece, ancient Chinese Sports Sports four parts, through the Western culture comparison of similarities, to systems and complete account of the history of sports in the world. In order to allow visitors to more images, specifically to understand ancient sports featured in "virtual Olympic Museum", design a lot of interaction with users, so that people can participate in the ancient sport.

In the virtual Olympic Museum, the technician passed motion capture technology (MotionCapture), collecting a lot of real players in action, on the movement of data processed, and then use it to control computer-generated 3-d virtual human movement, so that people can interact through the network, to personally experience the characteristics of ancient jump.

Unique is that in creating the simulation of long jump system, the technical staff has developed a powerful "sports editor", with it, you can make the captured motion data can be applied to different three-dimensional models, and can be in different movements smooth transition between data fragment. The "Virtual Museum" sports Olympics Editor, such as motion stitching, campaign integration, deformation and other technology, you can simulate different virtual people in different virtual scene complete virtual long action.
