Abstract
Disclosed is a polarized lens mobile structure of a 3D projection system. The polarized lens mobile structure of the 3D projection system comprises the 3D projection system for projecting multimedia content to a projection screen, a set of driving devices for generating a power source, a set of eyeglass mobile structures connected with the driving devices for bearing polarized lenses to carry out movement, and a platform for positioning and guiding the polarized lens mobile structure. The technical scheme provided by the invention has the advantages of compact and simple structure and easy realization.
Description
Technical field
The present invention relates to a kind of polarized lenses moving structure of 3D optical projection system, relate in particular to the 3D optical projection system of DLP light engine.
Background technology
3D is the abbreviation of English Three-Dimensional, also claims three-dimensional, is the digitized stereo technology based on computer/internet.3D video playback technology is that two overlapped images are projected in screen by stereo projecting equipment, makes beholder can experience the depth feelings of image.Project to two width images in screen, a width is received by left eye, and another width is received by right eye, the two width different images that receive by right and left eyes, and synthetic stereo image in brain, makes beholder experience the stereoscopic sensation of picture.Because of it, to have cost low in 3D shadow casting technique, and the advantages such as large scale, are widely used in the fields such as film, game, education, commercial affairs, mobile phone, and developed into a kind of mode of people's life, amusement.
3D technology be according to wearing spectacles can be divided into spectacle and bore hole formula, due to bore hole 3D technology exist at present resolution low, watch the shortcomings such as visual angle is little, be not also used widely.Therefore, the 3D technology of main flow mainly contains three classes: aberration formula, passive polarization type, active-shutter.Aberration formula is the early stage 3D technology occurring, because its colour loss is more serious, is replaced just gradually by latter two 3D technology.Although active-shutter 3D technology is widely used, and polarization type 3D becomes current main flow 3D technology shoulder to shoulder, and it is inevitable film flicker because shutter glasses brings, and watches for a long time, is easy to allow people produce strong discomfort such as dizzy grade.Meanwhile, the secondary shutter 3 D glasses of this 3D Technology Need one (needing to wear 3 D active eyeglasses), the price of a pair of glasses is (original equipment manufacture price) between 500-900 unit, has greatly increased the cost of watching 3D.And polarization 3D technology utilizes light to have the feature of polarization, make the light of different polarization direction enter human eye simultaneously, the spinning sensation that the flicker of avoiding completely brings, the cost of polaroid glasses is very low simultaneously, greatly reduces viewing cost in the time that many people watch 3D film.
Unit twin-lens polarization 3D shadow casting technique, adopts two projection lens to export respectively the polarized light of right and left eyes picture, after having the screen reflection that maintenance polarization characteristic is constant, enters eyes, forms 3D picture in brain.
The cinema system that adopts polarization 3D technology, by special playback equipment, carries out transmission by Liang Tai projector respectively by right and left eyes picture, can be described as the projection of two-shipper twin-lens.Mainly there is following shortcoming: first, need to adopt special video playback apparatus output signal, also need Liang Tai projector, not only the line between equipment is quite complicated, and the cost of equipment is also very high, has greatly limited the widespread use of polarization 3D technology.This special playback equipment+dual-projection system can only be built use at some special occasions such as movie theatres, if carry out equipment move and rearrange, install all very inconvenient.Secondly, this polarization optical projection system, in the time watching 2D film, cannot accomplish two width pictures to overlap completely.Therefore, while watching 2D film, must turn off a wherein projector, so not only cause equipment waste, also only have the half of two-shipper because closing of a projector causes brightness.Although this two-shipper polarization 3D optical projection system has 3D effect in the time watching 3D film, can be because not the overlapping completely of picture, (when distant view because the little picture of parallax overlaps) generation ghost image, allows people not feel well in film when some distant view.
The unit twin-lens 3D projector relating in patent CN201110144005.8, though be unit, the two-shipper projection actually and in current movie theatre there is no too big difference, is only that Liang Tai projector is fixed in integral type projection cabinet, common source.Though the loaded down with trivial details of installation and wiring simplified by this projector, but still existing problems: by upside-down mounting wherein a projector realize picture coincidence meeting and have a very large variation range because the size of projected picture makes the distance between Liang Tai projector, use and operate very inconvenient.
Summary of the invention
The problem that the present invention solves is that the stereo projection system polarized lenses that can not produce polarized light in prior art is installed inconvenience, after polarized lenses fixes, just can not move.
For addressing the above problem, the invention provides a kind of automated movement mode of polarized lenses of polarization type 3D optical projection system.
Compared with prior art, technique scheme has the following advantages:
The automated movement structure of polarized lenses of the present invention, for not producing the optical projection system of polarized light, in the time that polarized lenses moves to the position overlapping with light engine, coordinate Video processing just can form 3D optical projection system, optical projection system stereoeffect is now good, it is comfortable to watch; In the time that polarized lenses moves to the position not overlapping with light engine, just can form 2D optical projection system, optical projection system brightness is now high, picture is clear.
