Abstract
The utility model relates to a spherical screen theater system adopting double projectors to carry out projection, which structurally comprises a spherical screen, the movie projectors with fish-eye lenses and floor-type audience seats. The spherical screen theater system has the key points that two movie projectors are arranged; the first projector is arranged at the lowermost point of the spherical screen; the second projector is arranged at the highmost point of the spherical screen; and the elevation angle of the first projector is equal to the depression angle of the second projector. The spherical screen theater system has the beneficial effects that due to the utilization of the technology, firstly, a movie is stored in a digital mode, so that factors similar with physical scratches on a film and the like, which influence the image effect, cannot be generated and the movie is convenient to store and is easy to back up; after the movie projection is finished, the movie can be played again without being rolled back, and thus, in the case of a large tourist amount, the playing efficiency can be higher; and a row of seats can be added at the optimal viewing position of the spherical center of the spherical screen.
Description
Technical field
The utility model belongs to the cinema projection technical field, relates to a kind of ball screen cinema, is a kind of ball screen cinema system of dual-projection machine projection specifically.
Background technology
Traditional ball screen cinema is normally play film with film projector, and film projector is installed near the centre of sphere of ball curtain, through a fish eye lens, the picture on the film is projected on the ball curtain.This projection mode, cut and physical damnification appear in cinefilm easily, therefore will change film one time in common about three months, otherwise the cut on the film can seriously influence the movie pictures effect.Owing to be physical medium, the depositing and safeguard also cumbersome of cinefilm.And traditional film projector generally is installed in the position of ball curtain focusing center, therefore taken the best viewing location in the movie theatre.
Summary of the invention
The purpose of this utility model is in order to improve the defective of prior art, the position that the best is watched allows out, offer as far as possible the technical task that spectators appreciate, experience, designed a kind of ball screen cinema system of dual-projection machine projection, the quantity of traditional projector is set to two, one in the above, and one below, and two projectors get to picture on the ball curtain simultaneously.
The utility model for realizing the technical scheme that goal of the invention adopts is, the ball screen cinema system of dual-projection machine projection, comprise the ball curtain in the structure, with fish-eye motion-picture projection machine and floor-type rush seat, key is: the quantity of described motion-picture projection machine is set to two, the first projector is arranged on the minimum point of ball curtain, the second projector is arranged on the peak of ball curtain, and the elevation angle of the first projector equates with the angle of depression numerical value of the second projector.
The beneficial effects of the utility model are, use present technique, and at first film is to adopt the digital form storage, the factor that similar physical film cut etc. affect picture effect can not occur, and storage easily and is easy to back up; Because film projection just need not to rewind and can again show after finishing, when visitor's amount was larger, playing frequency can be higher; On this best viewing location of the ball curtain centre of sphere, also can increase by row's seat.
Description of drawings
Fig. 1 is system architecture synoptic diagram of the present utility model.
1 represents the ball curtain, and 2 represent the first projector, and 3 represent the second projector, and 4 represent the floor-type rush seat.
Embodiment
The ball screen cinema system of dual-projection machine projection, comprise ball curtain 1 in the structure, with fish-eye motion-picture projection machine and floor-type rush seat 4, key is: the quantity of described motion-picture projection machine is set to two, the first projector 2 is arranged on the minimum point of ball curtain 1, the second projector 3 is arranged on the peak of ball curtain 1, and the elevation angle of the first projector 2 equates with the angle of depression numerical value of the second projector 3.
Described the first projector 2 and the second projector 3 are digital-code projectors, the first projector 2 be connected projector 3 and be connected with computing machine respectively.
The wide ratio of described fish-eye throwing is not more than 43: 100.
Use this projection mode, two projectors are installed in respectively the height of ball curtain minimum point and peak, apart from the certain distance in ball curtain edge.Be contained in the first following projector 2 and throw from the bottom up the picture of top half screen, projecting direction is towards facing upward; The second projector 3 of top loading throws following half screen-picture from top to bottom, projecting direction is to nutation, the angle of depression numerical value of the elevation angle of following projector and top projector equates that two pictures have certain overlapping region at the equatorial line place of physics ball curtain, is used for merging.
Because the picture of each projector will cover the ball curtain zone above half, therefore need to strengthen view field with the fish eye lens of special customization, the focal length of this specific customization camera lens is very short, and is relatively more severe to the torsional deformation effect of projector's picture.Normal projected picture should be square-folded, but behind the customization camera lens, the picture that projector casts out is not square, with some distortions, then in the virtual scene of three-dimensional software, play up in the finished product picture, must carry out some to projected picture and process, be twisted the deformation effect that causes by camera lens with compensation.
Claims (3)
1. the ball screen cinema system of dual-projection machine projection, comprise ball curtain (1) in the structure, with fish-eye motion-picture projection machine and floor-type rush seat (4), it is characterized in that: the quantity of described motion-picture projection machine is set to two, the first projector (2) is arranged on the minimum point of ball curtain (1), the second projector (3) is arranged on the peak of ball curtain (1), and the elevation angle of the first projector (2) equates with the angle of depression numerical value of the second projector (3).
