Description

Three-point fix projection correction system
Technical field
The present invention relates to projection art, and in particular to three-point fix projection correction system.
Background technology
Projecting apparatus is also known as projector, is by image or video by digital optical processing technique or LCD liquid crystal imagings technology The equipment for projecting or reflexing on screen, can be by different signal sources, and such as computer, mobile phone, DVD, DV access are corresponding Image and vision signal, realize and play.Projecting apparatus is widely used in the places such as education, commercial affairs, engineering, family expenses.
Shadow instrument is classified according to the application environment of projecting apparatus, is broadly divided into following five class:1st, home theater type;2nd, portable commercial affairs Type projecting apparatus;3rd, educational conference type projecting apparatus;4th, main flow Engineering-type projecting apparatus;5th, professional theater type projecting apparatus;6th, measurement projection Instrument.
Several projectors of the above, portable business type projector, educational conference type projecting apparatus when in use, are frequently run onto so The problem of:Content in projector is usually in punch-drunk state when projecting on projection screen, and projection information can not be Show complete on projection screen, not only influence people's viewing and the visual field attractive in appearance, in addition it is also necessary to which cost time and manpower go adjustment to project The relative position of machine and projection screen, is bothered very much.
The content of the invention
It is an object of the invention to provide three-point fix projection correction system, projection can not be believed by solving existing projector Breath is regularly projected on projection screen, is caused the projection information on projection screen incomplete, is unfavorable for the problem of people watch.
The present invention is achieved through the following technical solutions:
Three-point fix projection correction system, including projection screen, projector, the projection screen are rectangle, in projection screen Three RF transmitters are installed on cloth, two of which RF transmitter respectively on two corners of projection screen, Another RF transmitter is located on an arm of angle of projection screen, the lines of three RF transmitters surround three The angular center line on projection screen is symmetrical;
The face that the projector is provided with camera lens is rectangle, in projector towards being additionally provided with three on the face of projection screen Infrared receiver, what the triangle and the line of RF transmitter that the line of the infrared receiver is surrounded were surrounded Triangular is overlapped into a triangular pyramidal, the center line of the triangular pyramidal with the center line of camera lens;Also set in projector It is equipped with angle adjusting mechanism, height adjustment mechanism, controller, the infrared receiver, angle adjusting mechanism, height regulation machine Structure is connected with controller, wherein:
Infrared receiver:The infrared signal that receiving infrared-ray transmitter is sent, and infrared signal is transferred to control Device processed;
Controller:The infrared signal of receiving infrared-ray receiver transmission, when synchronization receives only one or two During infrared signal, angular adjustment signal is sent to angle adjusting mechanism, height Regulate signal to height adjustment mechanism;When simultaneously When receiving 3 infrared signals, send stop adjustment signal to angle adjusting mechanism, height adjustment mechanism respectively;
Angle adjusting mechanism:The angular adjustment signal that controller is sent is received, the angle of projector is adjusted;Receive controller The stopping adjustment signal of transmission, is stopped;
Height adjustment mechanism:The height Regulate signal that controller is sent is received, the height of projector is adjusted;Receive controller The stopping adjustment signal of transmission, is stopped.Further, the present invention devises one kind and can throw projection information accurate projection System on shadow curtain, installs RF transmitter on projection screen, and infrared receiver is installed in projector, and three red Outer line receiver and RF transmitter are monolithically fabricated a triangular pyramidal, i.e., one infrared receiver and an infrared ray are sent out Emitter is corresponded, the infrared ray of receiving infrared-ray transmitter transmitting.When synchronization receives only one or two infrared ray During signal, controller control angle adjusting mechanism, height adjustment mechanism are adjusted, until three infrared receivers can be simultaneously Receive infrared ray information.When three infrared receivers receive infrared ray information simultaneously, illustrating the camera lens of projector just The well center just to projection screen, can be projected to information is regular on projection screen.Two RF transmitters are located at respectively On two corners of projection screen, another RF transmitter be located on an arm of angle of projection screen, three infrared rays hair The triangle that the line of emitter is surrounded is symmetrical on the center line of projection screen, ensures that projection screen is entirely located in projector with this Camera lens institute mapping range, projection information shows complete on projection screen.Existing projector is solved not by above structure Projection information can be regularly projected on projection screen, cause the projection information on projection screen incomplete, be unfavorable for people The problem of viewing.
It is preferred that, the angle adjusting mechanism is arranged between projector and height adjustment mechanism.Height adjustment mechanism can Using electric lifting rod or electronic screw mandrel.Angle adjusting mechanism, height adjustment mechanism are existing product.
It is preferred that, in addition to ceiling mounted support, one end and the angular adjustment machine of the height adjustment mechanism Structure connection, the other end and support are connected.
It is preferred that, sliding screw platform, the height adjustment mechanism and the cunning in sliding screw platform are additionally provided with support Block is connected.Further, by change sliding block position can the projector that is connected with height adjustment mechanism of convenient movement, changed with this Become position of the camera lens with respect to projection screen central point of projector, more with practicality.Sliding screw platform is in the prior art Conventional screw mandrel platform, during installation, screw mandrel and plane-parallel in sliding screw platform, the center line of height adjusting structure and slip Screw mandrel is mutually perpendicular to.
The present invention compared with prior art, has the following advantages and advantages:
Three-point fix projection correction system of the present invention, solving existing projector can not regularly project projection information On projection screen, cause the projection information on projection screen incomplete, be unfavorable for the problem of people watch, it is convenient and practical.
