Abstract
The invention discloses a method for transforming an actual scene into a virtual scene in the computer and reappearing the actual scene, in particular a method for visiting scenic spots by users through a multimedia system. The method provided by the invention comprises the following steps of: shooting multiple panoramic photographs in a real area and packaging all obtained panoramic photographs to obtain virtual scene data of the real area; when users access the virtual scene data through special browse software, obtaining the completely real feeling of being personally on the scene.
Description
Technical field:
The present invention relates to a kind of method that actual scene is converted into virtual scene in the computing machine and reproduces, relate in particular to the method that a kind of user of making goes sight-seeing the sight spot by multimedia system.
Background technology:
Virtual reality is to utilize computer simulation to produce a three-dimensional virtual world, and the user is provided the simulation about sense organs such as vision, the sense of hearings, allows the user as being personally on the scene, and can observe the things in the three-dimensional space in time, ad lib.The main computed real-time calculating of present virtual reality technology produces graphic scene, so that the user to be provided the simulation about the visual perception.This technology is widely used in aspects such as education, geography, city planning, indoor design, recreation, tourism.But present technology has following defective: 1. emulation degree is low, can't visually give the user real fully sensation; 2. simulated effect is coarse, and cost is higher aspect treatment of details; 3. it is higher to carry out the time cost of model construction for delicate items or environment.
Summary of the invention:
The purpose of this invention is to provide a kind of outdoor scene virtual reality method.In order to overcome above-mentioned defective, technical scheme of the present invention is as follows:
A kind of outdoor scene virtual reality method may further comprise the steps:
A. in real zone, take many Zhang Quanjings photo, may further comprise the steps:
A1. determine that the visitor can free movable zone, this zone is the visual human can free movable zone in virtual scene, is called the reality zone;
A2. determine a plurality of observation places in this zone, the observation place is the position that the visitor can stop, and also is the position that the visual human can stop in virtual scene, and the visitor can rest on the observation place so that surrounding environment is observed;
A3. use photographic instrument in each observation place to the surrounding environment photo that pans.
B. encapsulate taking resulting whole distant view photographs among the step a, obtain the virtual scene data in reality zone, may further comprise the steps:
Observation place at photographic instrument place was numbered when b1. all distant view photographs that shooting among a is obtained were taken according to it;
B2. all distant view photographs after will numbering are placed under the same catalogue or with them and write same data file, and this catalogue file or data file are called the virtual scene data in reality zone.
C. the user conducts interviews to the virtual scene data by special-purpose browsing software, and the job step of browsing software comprises:
C1. determine current visual human in virtual scene residing position and facial towards;
C2. select and the corresponding distant view photograph in the current present position of visual human, the position at photographic instrument place is the observation place in the pairing real zone, the current present position of visual human when taking this distant view photograph;
C3. selecting and the pairing image-region of the current face orientation of visual human in the resulting distant view photograph of c2, the content of this image-region is the current viewed scene of visual human;
C4. on display, play through the resulting image-region of c3;
C5. the request that real-time supervisory user is sent browser is with direction of motion and the facial rotation direction that obtains the visual human;
C6. according to determining residing position of visual human and face orientation subsequently through the resulting visual human's of c5 direction of motion, facial rotation direction and visual human's present located position and face orientation;
C7. use the residing position of visual human subsequently and the face orientation that obtain through c6 to upgrade residing position of current visual human and face orientation;
C8. repeat c2 to c7.
The indication distant view photograph is spherical panorama photo or cylindricality distant view photograph among the above-mentioned a.
Among the above-mentioned c, when the picture number of being play in a second during more than or equal to 48, the flicker that the user is produced when just not recognizing image switching.
Among the above-mentioned c, when the picture number of being play in a second more than or equal to the content of 16 and these images when changing continuously, the user just can observe the continually varying picture, and produces the sensation of walking in actual environment very really.
The present invention has following advantage:
1. picture is the outdoor scene picture, visually gives the user real fully sensation.
2. the user can control visual human's smooth arbitrarily activity in virtual scene, and can change arbitrarily visual human's face towards, thereby change its visual angle.
3. real-time, the picture smoothness, less demanding to the employed computing machine of user.
4. the complexity of the constructions cost of virtual environment model and true environment itself is irrelevant, and therefore, when the true environment complexity was higher, the cost of this method was more cheap.
5. be convenient to combine the experience that the user is reached be personally on the scene fully with systems such as stereophonic sound system and senses of touch.
