System, it is intended to lift the show quality of 3D films, the excellent viewing experience of spectators is brought in each viewing position.
The embodiment of the present invention is achieved in that a kind of projection quality of the 3D optical projection systems based on multiple spot detection evaluates system
System, including：
Projector, for projecting test image to metal curtain；
Multiple 3D glasses, default multiple test positions in Movie House are distributed in, are respectively used to the test position at itself
Receive the test image of metal curtain reflection；
Multiple first chroma-luminance testers, corresponded with the multiple 3D glasses, each first chroma-luminance test
Instrument is used for the chroma-luminance for detecting the test image of the left eyeglass by corresponding 3D glasses；
Multiple second chroma-luminance testers, corresponded with the multiple 3D glasses, each second chroma-luminance test
Instrument is used for the chroma-luminance for detecting the test image of the right eyeglass by corresponding 3D glasses；
Mass parameter evaluation module, it is connected, is used for the multiple first, second chroma-luminance tester
The result of detection of multiple first chroma-luminance testers is averaged, survey of the obtained evaluation of estimate as left-eye image
Test result；The result of detection of multiple second chroma-luminance testers is averaged, survey of the obtained evaluation of estimate as eye image
Test result.
Further, the test image includes three width test charts, wherein the first width is black left-eye image, the white right side
Eye pattern picture, the second width are white left-eye image, black eye image, and the 3rd width is white left-eye image, white eye image；Institute
State mass parameter evaluation module and the first contrast level parameter is obtained according to the first width test chart first, then according to the second width test chart
The second contrast level parameter is obtained, average luminance parameter is obtained further according to the 3rd width test chart.
The present invention uses the 3D glasses worn during spectators' viewing in multiple station acquisition projection qualities parameter, recycling software
3D projection qualities are evaluated, projection quality of the 3D optical projection systems in whole Movie House can be intuitively recognized, be easy to make phase
It should adjust, it is ensured that the viewing quality of user.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
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, projection quality's evaluation systems of 3D optical projection systems provided by the invention include being used for
The projector of metal curtain projection test image, multiple 3D glasses 1, multiple first chroma-luminance testers 21, multiple second colors
Luminance test instrument 22, mass parameter evaluation module 3.
Wherein, projector is used to project in specific test image, such as the present invention to metal curtain, and test image includes
Three width test charts, it is as shown in the table：
Wherein, the first width is black left-eye image, white eye image, and the second width is white left-eye image, black right eye
Image, the 3rd width are white left-eye image, white eye image.
Mass parameter evaluation module 3 can obtain following quality parameter information according to above-mentioned three width test image：Root first
The first contrast level parameter is obtained according to the first width test chart；Then the second contrast level parameter is obtained according to the second width test chart；Root again
Average luminance parameter is obtained according to the 3rd width test chart.Wherein first, second contrast is by the ratio of right and left eyes brightness, may be used also
The relation being further inversely proportional using crosstalk ratio and contrast obtains the crosstalk ratio of first, second width test image.3rd width is surveyed
The evaluation luminance parameter for attempting picture averages the brightness of right and left eyes.
, can be with the relevant operating parameter of manual or automatic adjustment projector, so that projection after obtaining above-mentioned mass parameter
