Abstract
A method for automatically regulating angle of projection by remote control includes series-connecting control horizontal motor-driven rotation pair and vertical motor-driven rotation pair between projector shell and fixing surface; connecting signal processor to video image signal, remote control reception, power supply, horizontal and vertical rotation driving; solidifying algorithm program of trapezoidal calibration in signal processor; using step pulse number as algorithm factor to carry out algorithm treatment on video image fro realizing geometric transform and for finally outputting calibrated video projection signal by signal processor.
Description
Technical field
The present invention relates to a kind of remote control and adjusted the method for angle.More particularly, related to a kind of method of Remote Control Automatic adjustment projection angle.
Background technology
As everyone knows: though existing projector kind has a lot.Up to the present, the technology that yet there are no is reliable, principle is simple, with low cost, can realize horizontal keystone correction and vertical keystone correction in pairs automatically to projected image; The optical projection system of remote-controlled automatic adjustment projection angle is come out.
Summary of the invention
The present invention provides a kind of method of a kind of Remote Control Automatic adjustment projection angle that is simple and easy to realize in order to overcome the deficiencies in the prior art.
The present invention adopts following technical scheme: it is made up of telepilot, projector, display screen, stationary plane and relative program, it is characterized in that: between the shell and stationary plane of projector, horizontal electric revolute pair that is being installed in series remote-controlled and vertical electronic revolute pair; Certainly, in horizontal electric revolute pair or the vertical electronic revolute pair any one also can only be installed; The input end of signal processor links to each other with system power supply with video signal, remote control reception, and the output terminal of signal processor drives and vertical rotation driving links to each other with horizontally rotating; In signal processor, be solidified with the algorithm routine of image keystone, signal processor is with the step-by-step impulse number the exported variable factor as image keystone algorithm, go algorithm process that video signal is correlated with, to realize the geometric transformation of image, the video-projection signal that the output of final signal processor is calibrated.
The invention has the beneficial effects as follows: one, can realize beyond thought Remote Control Automatic adjustment projection angle, conveniently watch; Two, can realize the horizontal keystone correction and the vertical keystone correction of projected image automatically, hommization more; Three, can make things convenient for the installation of any position of projector and angle and putting.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation; Fig. 2 is the schematic block diagram that embodiment of the invention related hardware is formed.
Among the figure: the 1st, telepilot; The 2nd, the horizontal electric revolute pair; The 3rd, vertical electronic revolute pair; The 4th, projector; The 5th, display screen.
Embodiment
According to Fig. 2, will realize successively being electrically connected except that the each several part telepilot, horizontal electric revolute pair and the vertical electronic revolute pair (comprise system power supply and " "), and be installed in the projection casing.Press Fig. 1 again, between the shell and its stationary plane (as ceiling or wall) of projector 4, horizontal electric revolute pair 2 (as stepper motor) that is installed in series remote-controlled and remote-controlled vertical electronic revolute pair 3 (as stepper motor); In signal processor, be solidified with the algorithm and the relative program of horizontal keystone correction and vertical keystone correction.Connect system power supply, just can realize the present invention.
Principle of work: receive when signal processor that remote control receives and send here when requiring instruction that projector horizontally rotates, will export step-by-step impulse and go to drive horizontal electric revolute pair (stepper motor) rotation, change its horizontal direction projected angle through horizontally rotating to drive.Owing between the anglec of rotation of stepper motor and the step-by-step impulse that is driven, the corresponding relation of determining is one by one arranged.Signal processor goes the algorithm process that video signal is correlated with and realizes geometric transformation, thereby obtain and export calibrated video-projection signal with the step-by-step impulse number the exported variable factor as image keystone algorithm.Finally make the image that is projected on the display screen, realize horizontal keystone correction automatically.(principle of vertical direction keystone and method, identical fully with horizontal direction." level " in the narration of just needing to be correlated with becomes " vertically " and gets final product.So be omitted herein, no longer repeat.)
Specify:
One, the present invention is not confined to illustrated embodiment.Be horizontal electric revolute pair and vertical electronic revolute pair positional structure order, can exchange.
Two, horizontal electric revolute pair of the present invention and vertical electronic revolute pair, both remote-controlled direct motor drive; Also remote-controlled other electric structures drive.
Three, the present invention drives horizontal electric revolute pair and vertical electronic revolute pair, is not confined to stepper motor; Also can be other controllable motors.
Four, remote control mode of the present invention both can adopt traditional infrared wireless remote control; Also can adopt radio frequency or other wireless modes to carry out remote control.
Five, video signal of the present invention can be external various video signals; Also can be built-in video frequency program source signals such as DVD.
