Standard 3D glasses, its optical property meet viewing standard, are placed on the reflected light path of the metal curtain, its left eyeglass
The 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 glasses
The 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 standard
Left-eye image brightness value；
Second chroma-luminance tester, for separately detecting right eyeglass through 3D glasses to be measured and the standard 3D glasses
The 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 standard
Eye image brightness value；
3D glasses performance evaluation modules, are connected with the first chroma-luminance tester, the second chroma-luminance tester, use
According 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 measured
Analysis result, according to the eye image brightness value to be assessed and standard right eye image brightness values generation on 3D glasses to be measured
Right eyeglass analysis result.
Further, the 3D glasses performance evaluation module is specifically left by the left-eye image brightness value to be assessed and standard
Eye image brightness values make the difference, if difference, in default deviation range, analysis result is the left lens performance of 3D glasses to be measured
Meet 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 default
In 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 glasses
Survey 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 measured
Whether the optical property of mirror meets viewing standard, the regular maintenance available for movie theatre 3D glasses.
Brief description of the drawings

The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It 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 curtain
Image, 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 put
In 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 one
Reference 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 reflects
Test 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 reflects
It 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 measured
