Abstract
The invention belongs to the technical field of image display and particularly relates to a multi-projection immersion display system of a large visual field. The multi-projection immersion display system comprises a control center, a connecting wire, an ellipsoidal curtain and a projection device. By the application of the system, each point on the curtain can be ensured to be covered by projectors in an overlapped manner for less than or equal to three times, the projectors are closer to the curtain under the condition that the projectors with the same projection ratio are used, and better projection effect is achieved. By the arrangement, viewers can be at the central zone of the ellipsoidal curtain, and light paths of the projectors cannot be shielded during the viewing process.
Description
Technical field
The invention belongs to image display technology field, display system is immersed in the many projections particularly relating to a kind of Large visual angle.
Background technology
Immersion display (Immersive Display) technology is a kind of advanced person, digitized human-machine interface technology, its feature is a kind of artificial virtual environment that computer produces, generate an artificial environment based on visual experience, people can by the virtual world of stereoscopic vision perception computer simulation, also can be undertaken alternately by the most natural modes such as motion, voice, expression and gesture and virtual world, thus produce immersion experience on the spot in person.Immersion Display Technique is the comprehensive development of the multiple technologies such as computer technology, sensor technology, human-computer interaction technology and artificial intelligence technology, is applied in military affairs, medical science, education, amusement, manufacturing industry and engineering training etc. at present.
Immersion display system is realized by some special external equipments, high-performance computer and corresponding software.Existing immersion display system comprises cave immersive VR display system, helmet-type three-dimensional stereo display system, cylinder ring curtain projection immersion display system, the level and smooth immersion display system of Spherical Ring curtain projection immersion display system and full visual angle etc.
Cave immersive VR display system is large-scale virtual reality (Virtual Reality, VR) system, but this system cost is expensive, requires higher, cannot promote widely scene environment.Meanwhile, immersive VR display system in cave cannot obtain really seamless, the virtual display frame of continuous print.
Helmet-type three-dimensional stereo display system utilizes helmet-mounted display or other equipment, and by the vision of participant, the sense of hearing etc., other feel to be closed, provide one new, virtual sense space.But the current general resolution of helmet-type three-dimensional stereo display system is low, and visual field is wide not, easy visual fatigue, cannot be easily accepted by a user.
If application publication number is for as described in the patent of CN104168315A, full visual angle level and smooth immersion display system uses the display device display image of multiple arbitrary form, adopts the image of spherical panoramic image or Practical computer teaching to carry out the immersion display of full visual angle.But this system needs to preset equipment angle, amount of calculation is large, and computational process is complicated.
Cylinder ring curtain projection immersion display system projects on annular screen by the projected image of plane through nonlinear distortion geometric correction, but this system can only provide the panoramic picture on horizontal direction visual angle, lack vertical direction multi-view image, really cannot realize the height feeling of immersion of display frame.The shortcoming of vertical direction multi-view image is lacked in order to overcome cylinder ring curtain projection immersion display system, occur that screen is just spherical sphere curtain projection immersion display system, the software platform that this system requirements is equipped with must possess the ability of software flake mirror perspective correction, otherwise the object in the visual field will gross distortion, and the spherical height of standard is determined by the radius of a ball, can not change, often propose excessive demand to building floor height, oval ball curtain has then been difficult to correction.。Simultaneously, Spherical Ring curtain projection immersion display system is being carried out in multi-projector display process, the point that there will be on more projection screen body is projected the situation of number of times >=4 that machine overlap covers, this situation can cause more serious light leak zoning, affect the uniformity of fused images, for improving drop shadow effect, aberration, bright difference and the uniformity between needing different projection signal adjust, and increase adjustment difficulty and the net effect of system.
