Abstract
The utility model is suitable for a 3D projection display technology field provides a high light efficiency 3D projection system's luminance homogeneity parameter acquisition system, include: the CCD array unit is positioned in front of the metal screen and used for detecting the brightness of a projected image; the surface of the CCD array unit is provided with a filter layer which only allows circularly polarized light to pass through. The utility model discloses a CCD array unit surveys the luminance of each region on the metal curtain, recycles outside software and generates the effect picture to the luminance homogeneity of metal curtain, can know 3D projection system's projection quality directly perceived, is convenient for make corresponding adjustment, can guarantee user's sight shadow quality.
Description
Technical field
The utility model belongs to 3D projection display technique field, particularly relates to a kind of brightness uniformity parameter acquisition system of specular removal 3D optical projection system.
Background technology
The appearance of 3D film, gives the sensory experience that spectators one are brand-new undoubtedly, and three-dimensional visual impact, strong fight scenes, add more stimulation to film.
And if can evaluate and then make according to evaluation result corresponding adjustment to the uniformity of projection brightness, then can more ensure spectators viewing experience.
Utility model content
The object of the utility model embodiment is the brightness uniformity parameter acquisition system providing a kind of specular removal 3D optical projection system, is intended to the show quality promoting 3D film, brings the excellent viewing of spectators and experiences.
The utility model embodiment is achieved in that a kind of brightness uniformity parameter acquisition system of specular removal 3D optical projection system, comprising:
One ccd array unit, is positioned at metal curtain front, for detecting the brightness of projected image;
The surface of described ccd array unit is provided with the filter course only allowing circularly polarized light to pass through.
Further, described ccd array unit comprises a substrate, and described substrate is provided with some CCD, the brightness of respective regions on each CCD correspondence detection metal curtain.
Further, described substrate is provided with heat-conducting plate.
The utility model embodiment is by the brightness in each region on a ccd array unit detection metal curtain, the software of recycling outside generates design sketch to the brightness uniformity of metal curtain, intuitively can recognize the projection quality of 3D optical projection system, be convenient to make corresponding adjustment, the viewing quality of user can be ensured.
Accompanying drawing explanation
Fig. 1 is the position view of the brightness uniformity parameter acquisition system of the specular removal 3D optical projection system that the utility model embodiment provides;
Fig. 2 is the schematic diagram of the ccd array that the utility model embodiment provides;
Fig. 3 is the structure principle chart of the brightness uniformity parameter acquisition system of the specular removal 3D optical projection system that the utility model embodiment provides;
Fig. 4 is the brightness uniformity design sketch that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please with reference to Fig. 1 to Fig. 3, the brightness uniformity parameter acquisition system of the specular removal 3D optical projection system that the utility model provides comprises ccd array unit 1, and this ccd array unit 1 is positioned at metal curtain front, for detecting the brightness of projected image.It comprises a substrate, and this substrate is provided with some CCD, the brightness of respective regions on each CCD correspondence detection metal curtain.What consider that metal curtain reflects is left-handed or right-circularly polarized light, ccd array unit 1 only needs to detect this left-handed or right-circularly polarized light, for having avoided surround lighting or other light interference detection results, the utility model is provided with the filter course only allowing circularly polarized light to pass through on the surface of ccd array unit 1, ensure the accuracy of detection.
Outside brightness uniformity design sketch generation module 2 is connected with ccd array unit 1, for the result of detection according to ccd array unit, generates the design sketch including the monochrome information of metal curtain regional.The design sketch generated as shown in Figure 4.
Receiving the light reflected generate heat for avoiding ccd array unit 1 and affect useful life, being provided with on substrate with heat-conducting plate especially, for the heat of convergence is distributed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
