Description
Technical field
The present invention relates to a kind of method and system for realizing virtual reality scenario.
Background technology
Virtual reality is the synthesis of multiple technologies, including real-time three-dimensional computer graphics techniques, wide-angle stereo display technique,
Feedback, stereo, network transmission, voice input and output skill are felt to the tracking technique and tactile of observer's head, eye and hand, power
Art etc..
In comparison, the thing that graph image is not too difficult is generated using computer model.If there is accurate enough
Model, and have time enough, we can generate the exact image of various objects under different illumination conditions, but here
Key be real-time.Such as in flight simulation system, the refreshing of image is quite important, while the requirement to picture quality is also very
Height, adds extremely complex virtual environment, and problem just becomes extremely difficult.
The universal time that people looks around, since the position of two eyes is different, obtained image is slightly different, these images exist
Fusion is got up in brain, is formed a whole scene about world around, is included distance in this scene
Information.Certainly, range information can also be obtained by other methods, for example, the distance of eyes focal length, article size comparison etc..
In VR systems, binocular stereo vision has played great role.The different images that two eyes of user are seen are point
It does not generate, is shown on different displays.After some systems use individual monitor, but user takes special glasses,
One eye eyeball can only see odd-numbered frame image, and another eyes can only see even frame image, between odd, even frame it is different also
It is that parallax just produces three-dimensional sense.
The tracking of user's (head, eye)：In artificial environment, each object relative to system coordinate system there are one position
With posture, and user is also such.The scene that user sees is determined by the position of user and the direction of head (eye).
Track the virtual reality headgear of head movement：In traditional computer graphics techniques, the change of visual field is to pass through
Come what is realized, the vision system and motion perception system of user are separation, and are changed using head tracking for mouse or keyboard
The visual angle of image can connect between the vision system and motion perception system of user, feel more true to nature.Another is excellent
Point is that user can not only remove epistemic context by binocular stereo vision, but also can remove environment of observation by the movement on head.
In the interaction of user and computer, keyboard and mouse are current most common tools, but three dimensions is come
It says, they are all unsuitable.In three dimensions because there are six degree of freedom, we are difficult to find out the intuitive method of comparison mouse
Target plane motion is mapped to the arbitrary motion of three dimensions.Now, there are some equipment that can provide six-freedom degree, such as
3Space digitizers and SpaceBall Spatial Spheres etc..The more excellent equipment of other performance is data glove and data
Clothing.

The various objects in virtual world are operated, to obtain impression on the spot in person and cognition.
Virtual reality technology has following five main features：
1) property immersed be allowed to created virtual environment can make student generate " feeling on the spot in person, makes it believe virtual
People is also to be implicitly present in, and what it can be from beginning to end in operation plays a role in environment, just as really objective
It is the same to see the world.
2 interactivity are task, thing of the student as in true environment and in virtual environment in virtual environment
Interactive relation occurs for object, and middle school student are interactive main bodys, and virtual objects are interactive object, the interaction between subject and object
It is comprehensive.
3 imaginations are that virtual reality is to want that the creative activity of people can be inspired, and not only want to make to be immersed in this environment
Student obtain new instruction, improve perception and rational knowledge, and want that student can be made to generate new design.
4 actions, which refer to student, to operate by the actual act of objective world or in such a way that the mankind are actual virtual system
System, allow student feels that he faces is a true environment.
5 independences are that object can be by respective model and regular autokinetic movement in virtual world.
