Description
Technical field
The present invention relates to a kind of plane and stereo-picture self-adaptation handoff technique of large scale LED display, belong to bore hole stereo display technique field.
Background technology
People are with the Liang Zhi eye observation world, and due to the scenery slightly difference that right and left eyes is seen, so the objective world seen is three-dimensional, therefore the rediscover world is the target that the mankind pursue always.Stereo display technique may be used for all many-sides such as military affairs, education, amusement, medical treatment, is day by day subject to the attention of countries in the world, and the country such as US and European has all dropped into the research that a large amount of strength carries out this respect, achieves very large achievement.Stereo-picture display technique wherein based on parallax technology is widely used to realize the advantage of convenient and technology maturation.
Traditional stereo display technique is non-is bore hole formula and Wearable two type.Wearable stereo display utilizes the technology such as timesharing, light splitting, color separation the two width pictures with parallax of correspondence to be delivered to respectively the left and right eyes of people, merged by brain and form good stereo display effect, but its shortcoming needs observer to wear relevant device, as glasses etc., therefore to being that user is very inconvenient; And bore hole formula stereo display technique, the scene of approaching of " ready to appear, body faces wonderland " without the need to wearing any utility appliance, can be appreciated, being more and more subject to the favor of people.On market, the bore hole formula stereo display technique of main flow is divided into slit shading type and column mirror grating formula, and slit shading type display screen light percent of pass is the highest only has 50%, and energy consumption is high, will by market; Column mirror grating relies on anaclasis principle, and therefore light percent of pass loses hardly, and this technology occupation rate is high.
For bore hole stereo technology, the size of display screen is larger, the stereoscopic sensation produced is stronger, more shock, along with the technology of LED display reaches its maturity, point is apart from more and more less, meet the requirement of bore hole stereo display, therefore increasing company puts into bore hole LED stereo display, but bore hole stereo display technique requires that corresponding display screen must input the image that at least 2 pairs have stereoscopic parallax, the general corresponding horizontal viewing distance of every secondary stereo-picture is 65mm, for LED giant-screen, viewing distance is all several meters even scope of tens meters, therefore 2 secondary anaglyphs are only had, horizontal viewing distance only has 130mm to be obviously inadequate, therefore in order to meet multi-angle, many people bore hole stereo display requirement, the anaglyph sequence of general employing 8 pair or more, level is watched pleasant.But bore hole stereo display technique is also not immaculate, along with the expansion resolution of horizontal view angle is reduced to original
n represents adopted anaglyph sequence number.Therefore cause when display plane image, the content of plane picture is amplified by the refraction of bore hole stereoscopic column lens device, and plane picture cannot be seen clearly, has had a strong impact on the operation to plane picture content.
Summary of the invention
When the bore hole stereo technology existence that the present invention seeks to solve large display screen switches back plane display, the unclear problem of its plane picture, provides the LED display packing that a kind of plane/stereo switches mutually.
The LED display packing that a kind of plane/stereo of the present invention switches mutually, the stereo-picture of the method adopts column mirror grating technology to realize, and arranges post mirror device before LED display, and described post mirror device adopts Lenticular screen to be attached on glass plate and realizes,
The method comprises the following steps:
Step one, judge whether pre-display file is stereo-picture; Judged result is yes, performs step 2, switches to stereo-picture display mode; Judged result is no, shows that pre-display file is plane picture, performs step 3, switches to plane picture display mode;
Step 2, utilize retractor device to adjust the distance D of LED display and the saturating device of post, make LED display be positioned near the focal position of Lenticular screen, namely meet relational expression D=f ± 2mm, wherein f is the focal length of Lenticular screen; Return after playing current file and perform step one;
Step 3, utilize retractor device to adjust the distance D of LED display and the saturating device of post, and meet relational expression D≤f/4mm; Return after playing current file and perform step one.
Advantage of the present invention: the present invention adopts column mirror grating to be the bore hole LED three-dimensional display system of technology type, by identifying the filename of pre-display file, drive retractor device, control the self-adaptation switching that post mirror device moves forward and backward to realize plane picture and stereo-picture, this programme advantage is to adopt the three-dimensional LED screen of the bore hole of this device when not showing stereo-picture (3D rendering), do not affect the normal running of people to this system, plane picture (2D image) is clear and legible, namely this system and common LED giant-screen are without any difference, and the switching of screen picture and stereo-picture is that computer controls automatically, can according to the content-adaptive adjustment of playing.Solving bore hole stereo display and differentiate the problem declined, is the development important in inhibiting of large scale bore hole stereo display technique.
