Abstract
The invention is suitable for the technical field of 3D projection display, and provides a projection quality evaluating system of a 3D projection system. The projection quality evaluating system of the 3D projection system comprises a projector used for projecting tested images to a metal curtain; 3D glasses used for receiving the tested images reflected by the metal curtain; a first color brightness tester used for detecting the color brightness of the tested images through a left lens of the 3D glasses; a second color brightness tester used for detecting the color brightness of the tested images through a right lens of the 3D glasses; a quality parameter evaluating module connected with the first and second color brightness testers and used for analyzing color brightness parameters detected by the first and second color brightness testers and making a quality evaluating result. According to the invention, projection quality parameters are collected by the 3D glasses worn by an audience in a film watching process, and the 3D projection quality is evaluated through software, so that the projection quality of the 3D projection system can be understood visually, corresponding adjustment can be made conveniently, and the film watching quality of a user can be ensured.
Description
Technical field
The invention belongs to 3D projection display technique field, particularly relate to a kind of projection quality's evaluation system of 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 show quality and then make corresponding adjustment according to evaluation result, then can more ensure spectators viewing experience.
Summary of the invention
The object of the embodiment of the present invention is the projection quality's evaluation system providing a kind of 3D optical projection system, is intended to the show quality promoting 3D film, brings the excellent viewing of spectators and experiences.
The embodiment of the present invention is achieved in that a kind of projection quality's evaluation system of 3D optical projection system, comprising:
Projector, for projecting test pattern to metal curtain;
3D glasses, for receiving the test pattern of metal curtain reflection;
First chroma-luminance tester, for the chroma-luminance of the left eyeglass probing test image by described 3D glasses;
Second chroma-luminance tester, for the chroma-luminance of the right eyeglass probing test image by described 3D glasses;
Mass parameter evaluation module, is connected with first, second chroma-luminance tester described, analyzes, make quality evaluation result for the chroma-luminance parameter detected first, second chroma-luminance tester described.
Further, described 3D glasses are placed near projector.
Further, described test pattern includes three width test patterns, and wherein the first width is black left-eye image, white eye image, and the second width is white left-eye image, black eye image, and the 3rd width is white left-eye image, white eye image;
First described mass parameter evaluation module obtains the first contrast level parameter according to the first width test pattern, then obtains the second contrast level parameter according to the second width test pattern, then obtains average luminance parameter according to the 3rd width test pattern.
The present invention adopts the 3D glasses acquired projections mass parameter worn during spectators' viewing, and recycling software is evaluated 3D projection quality, intuitively can recognize the projection quality of 3D optical projection system, be convenient to make corresponding adjustment, can ensure the viewing quality of user.
Accompanying drawing explanation
Fig. 1 is the position view of projection quality's evaluation system of the 3D optical projection system that the embodiment of the present invention provides;
Fig. 2 is the structure principle chart of projection quality's evaluation system of the 3D optical projection system that the embodiment of the present invention provides.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please with reference to Fig. 1, Fig. 2, projection quality's evaluation system of 3D optical projection system provided by the invention comprises projector, 3D glasses 1, first chroma-luminance tester 21, second chroma-luminance tester 22, mass parameter evaluation module 3.
Wherein, projector is used for projecting specific test pattern to metal curtain, and such as, in the present invention, test pattern includes three width test patterns, 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 eye image, and the 3rd width is 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 patterns: first obtain the first contrast level parameter according to the first width test pattern; Then the second contrast level parameter is obtained according to the second width test pattern; Average luminance parameter is obtained again according to the 3rd width test pattern.Wherein first, second contrast is the ratio of right and left eyes brightness, and the relation that also can crosstalk ratio and contrast be utilized further to be inversely proportional to obtains the crosstalk ratio of first, second width test pattern.The brightness of right and left eyes is averaged by the evaluation luminance parameter of the 3rd width test pattern.
After obtaining above-mentioned mass parameter, manually or automatically can adjust the relevant operating parameter of projector, to make projection quality optimum, the size of current such as adjusting light source of projector can make brightness change.
In the present invention, consider projector's general distance metal curtain farthest, 3D glasses 1 are placed on carry out acquired projections mass parameter, with the projection quality of the whole Movie House of maximum objective evaluation near the position of projector especially.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
