The cave projection module mainly through structural projection, AR technique, creates the high resolution, and the immersive space that the picture stereovision is strong gives people and brings 1: 1, strong image impact force and infection force are generated. The CAVE immersive projection system is a large projection display system for realizing virtual reality, as shown in fig. 1, and includes a laser projection system, a cascade server, a wireless positioning device, and a positioning tracker, and by using computer graphics, a stereo, a sensor technology, a high-pixel stereo projection, a 3D graphics technology, and a multi-channel video technology are combined together to create an immersive virtual scene surrounded by a high-resolution stereo view, so that the interactive performance is strong, and people can be as if they are in the immersive virtual scene.

The CAVE immersive virtual system implementation scene is generally in an indoor space of four or six sides, and under the support of various technical means, people inside can arrive in a virtual simulation space, and can interact with the virtual scene inside, and feedback experience is experienced in the visual, audio and tactile sense, for example, the scene is in the real world, as shown in fig. 2.

Originally, realize and accomplish this kind of CAVE immersive projection's visualization, will use UNIX graphic workstation, and present high performance computer is more and more powerful to the graphics processing ability, and it is a very convenient work that partial function replaces UNIX with PC to accomplish, can guarantee the high-efficient processing of image, also can save the cost simultaneously, has cleared up some obstacles for the track clearance that this immersive projection technique is popularized.

If the CAVE immersive projection processing wants to replace a UNIX graphic workstation with high cost, 6 high configuration computers can be connected into a computing cluster system, each computer is respectively used for processing different 3D stereo images in the CAVE projection system, then correction and integration are carried out, the whole image is guaranteed to be high in resolution, distortion-free is carried out, and the output projection is carried out on an indoor wall, so that an immersive interactive space is realized.

The position that the projector arranged will calculate very accurately and ingenious, generally to projection screen ground distance about 3.7-5.8 meters, the actual distance needs on-the-spot continuous debugging, generally the projector position can be put behind the projection screen, carries out special treatment to the projection screen, guarantees that the tone is even unanimous, and screen frame avoids adopting iron metal frame simultaneously, prevents magnetic interference, the frame of wooden system or aluminium system is used preferably.

CAVE is used as a mature technology of immersive projection, the immersive experience sense of CAVE is strong, the interaction is good, the virtual implementation is realized, a good immersive experience space is designed, the space layout needs to be determined, the deeper the scene space is, the stronger the immersive sense of the scene space is, an excellent movie and television production team needs to be provided, a complete and hierarchical omnibearing three-dimensional picture is designed, a more three-dimensional picture is brought, and a larger visual impact force is brought to people.

The good immersive experience enables people to feel relaxed and happy, concentrate on existing scenes, and leave the real world fatigued. And the CAVE projection immersion type system can carry out immersion type projection in all directions by 360 degrees, and brings people impressive immersion type experience.
