The present invention is poor and can't realize panorama emulation for the simulated effect that solves existing emulation technology, has simultaneously the problem of emulator costliness, and a kind of four acts of splicing three-dimensional vision emulation modes are provided.
Four acts of splicing three-dimensional vision emulation modes, the method is realized by following steps:
Step 1, four rear projection screens are carried out the seamless spliced rear acquisition square screen in edge, the outside that again four projector is placed in square is rendered to the emulation what comes into a driver's on the every screen;
Scene on step 2, real-time step display one described four screens of employing two-server; Adopt a computing machine to provide external synchronization signal for described two-server;
Step 3, employing Vega software carry out model-driven, make up simulating scenes, set up four observers, observe respectively the scene on four screens from four orientation, realize the emulation of full visual angle.
Scene on real-time step display one described four screens of the described two-server of step 2: detailed process is: wherein a station server shows the scene on the left side, three screens in front and the right side in real time, and another station server shows the scene on the screen of back.
Principle of the present invention: the present invention is in order to strengthen the fidelity of emulation visual effect, the open emulation visual field, set up panorama emulation, also cheap simultaneously, method of the present invention is spliced into a square lattice by will just shielding rear projection screen, make the emulation participant place oneself in the midst of the central point of square, give panoramic view of participant, simultaneously by means of Vega software, four observers' viewing angle and direction of observation are set, the displaying contents of four screens is covered whole scene, give one of participant the visual simulation effect as on the spot in person.
Beneficial effect of the present invention: the present invention has strengthened the fidelity of visual simulation, has also enlarged the emulation visual field simultaneously, has realized panorama emulation, and the emulator of the inventive method is simple and cheap, is easy to allow users accept, and is convenient to promote.
