3D glasses performance detecting systemsTechnical field
The invention belongs to 3D projection display techniques field, more particularly to a kind of 3D glasses performance detecting system.
Background technology
The appearance of 3D films, has undoubtedly given one brand-new sensory experience of spectators, and three-dimensional visual impact is strong to beatStruggle against scene, and more stimulations are added to film.
3D glasses are that viewing impression of the performance such as device, its transmitance to light to spectators necessary to watch 3D films hasMaterial impact.The 3D glasses provided at present in movie theatre can all recycle use, and increasing for access times may also cause 3D glassesLens surface have the defects of spot, abrasion, scratch, directly reduce the quality of image that human eye receives.Therefore, to 3DAlso need to detect whether its performance meets viewing standard in the regular maintenance of mirror.
The content of the invention
The technical problems to be solved by the invention are the optical property for detecting 3D glasses, will not meet the 3D of viewing standardGlasses exclude, and ensure the viewing experience of spectators.
The present invention is achieved in that a kind of 3D glasses performance detecting system, including：
Projector, for projecting left eye test image and right eye test image to metal curtain；
Metal curtain, for reflecting the left eye test image and right eye test image；3D glasses to be measured are placed in the metalOn the reflected light path of curtain, the left eye test image that the left eyeglass of 3D glasses to be measured allows metal curtain to reflect transmits, and right eyeglass allowsThe right eye test image transmission of metal curtain reflection；
Standard 3D glasses, its optical property meet viewing standard, are placed on the reflected light path of the metal curtain, its left eyeglassThe left eye test image that metal curtain reflects is allowed to transmit, the right eye test image that right eyeglass allows metal curtain to reflect transmits；
First chroma-luminance tester, for separately detecting left eyeglass through 3D glasses to be measured and the standard 3D glassesThe chroma-luminance of the left eye test image of left lens transmission, result of detection is respectively as left-eye image brightness value to be assessed and standardLeft-eye image brightness value；
Second chroma-luminance tester, for separately detecting right eyeglass through 3D glasses to be measured and the standard 3D glassesThe chroma-luminance of the right eye test image of right lens transmission, result of detection is respectively as eye image brightness value to be assessed and standardEye image brightness value；
3D glasses performance evaluation modules, are connected with the first chroma-luminance tester, the second chroma-luminance tester, useAccording to the left eyeglass of the left-eye image brightness value to be assessed and the generation of standard left-eye image brightness value on 3D glasses to be measuredAnalysis result, according to the eye image brightness value to be assessed and standard right eye image brightness values generation on 3D glasses to be measuredRight eyeglass analysis result.
Further, the 3D glasses performance evaluation module is specifically left by the left-eye image brightness value to be assessed and standardEye image brightness values make the difference, if difference, in default deviation range, analysis result is the left lens performance of 3D glasses to be measuredMeet the requirements, then the eye image brightness value to be assessed and standard right eye image brightness values are made the difference, if difference is defaultIn deviation range, then analysis result meets the requirements for the right lens performance of 3D glasses to be measured.
Further, the 3D glasses close to projector place and it is close to each other.
The present invention as reference, is made standard 3D glasses and treated with the optical property of the 3D for meeting a viewing standard glassesSurvey 3D glasses and transmit the test image reflected through metal curtain at the same time, and transmission results are contrasted, and then judge 3D to be measuredWhether the optical property of mirror meets viewing standard, the regular maintenance available for movie theatre 3D glasses.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is rightThe present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, andIt is not used in the restriction present invention.
Please with reference to Fig. 1, Fig. 2,3D glasses performance detecting system provided by the invention include projector 1, metal curtain 2,Standard 3D glasses 3, the first chroma-luminance tester 4, the second chroma-luminance tester 5,3D glasses performance evaluations module 6.
Wherein, projector 1 is used to project specific test image, including left eye test image and right eye test to metal curtainImage, metal curtain 2 are used to reflect the left eye test image and right eye test image.Standard 3D glasses 3 and 3D glasses to be measured are putIn on the reflected light path of the metal curtain, the optical property of standard 3D glasses 3 meets viewing standard, in the present invention as oneReference data.
After being reflected through metal curtain 2, the left eyeglass of standard 3D glasses 3 and 3D glasses to be measured allows the left eye that metal curtain reflectsTest image is transmitted through, and the right eyeglass of standard 3D glasses 3 and 3D glasses to be measured allows the right eye test image that metal curtain reflectsIt is transmitted through.
First chroma-luminance tester 4 is used for the left side for separately detecting left eyeglass and standard 3D glasses 3 through 3D glasses to be measuredThe chroma-luminance of the left eye test image of lens transmission, result of detection are left respectively as left-eye image brightness value to be assessed and standardEye image brightness values.Similarly, the second chroma-luminance tester 5 is used to separately detect right eyeglass and the mark through 3D glasses to be measuredThe chroma-luminance of the right eye test image of the right lens transmission of quasi- 3D glasses 3, result of detection is respectively as eye image to be assessedBrightness value and standard right eye image brightness values.
3D glasses performance evaluations module 6 is connected with the first chroma-luminance tester 4, the second chroma-luminance tester 5 at the same time,For generating the left mirror on 3D glasses to be measured according to the left-eye image brightness value to be assessed and standard left-eye image brightness valueThe analysis result of piece, according to the eye image brightness value to be assessed and the generation of standard right eye image brightness values on 3D to be measuredThe analysis result of the right eyeglass of mirror.For example, the left-eye image brightness value to be assessed and standard left-eye image brightness value can be doneDifference, if difference, in default deviation range, analysis result meets the requirements for the left lens performances of 3D glasses to be measured, then by instituteState eye image brightness value and standard right eye image brightness values to be assessed to make the difference, if difference is divided in default deviation rangeAnalysis result meets the requirements for the right lens performance of 3D glasses to be measured.
After obtaining above-mentioned analysis result, " survival of the fittest " can be carried out to the 3D glasses tested accordingly, exclude not being inconsistentClose the 3D glasses of viewing standard.
In the present invention, it is contemplated that projector is generally farthest apart from metal curtain, especially by standard 3D glasses 3 and 3D glasses to be measuredThe position of projector is disposed close to detect brightness, and makes the two close, farthest to obtain more objectively analyzingAs a result.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present inventionAll any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
