3D (three-dimensional) polarization screen testing method

Abstract

The invention provides a 3D (three-dimensional) polarization screen testing method, which comprises steps that a. generating an image of a first random number for a left eye to view and an image of a second random number for a right eye to view; b. respectively polarizing the image of the first random number and the image of the second random number; c. displaying the polarized images of the random numbers on a 3D polarization screen to be tested after the polarized images are superposed; and d. inputting a random number actually seen by a left eye of a tester, comparing the random number with the first random number generated in the step a, inputting a random number actually seen by a right eye of the tester, comparing the random number with the second random number generated in the step a, judging whether the random numbers actually seen by the left eye and the right eye of the tester are completely identical to the first random number and the second random number or not, determining that the 3D polarization screen to be tested displays normally and returning to test normally finished test results if the random numbers actually seen by the left eye and the right eye of the tester are completely identical to the first random number and the second random number, and returning to the step a if the random numbers actually seen by the left eye and the right eye of the tester are not completely identical to the first random number and the second random number. The 3D polarization screen testing method replaces subjective standards for judging the quality of a screen by the aid of 3D vision perception of people, and gets rid of influence to a screen judging result due to subjective factors of people.

Description

technical field [0001] The invention provides a test method, in particular to a test method for a 3D polarized screen. Background technique [0002] The current method of testing 3D screens is to directly use the 3D screen to play 3D movies. The testers need to wear 3D glasses specially equipped with polarizers to watch movies to judge whether the 3D screen shows 3D effects. For the display, if you want to see 3D images, the prerequisite is that the screen can normally display polarized images for left eye viewing and right eye viewing respectively. After wearing polarized glasses, the left eye can see the imaging output of the left eye, and the right eye can see the right eye. It can be judged that the 3D polarized screen display is normal. [0003] Because the 3D visual effect of this method varies from person to person, many people may not be able to immediately see the 3D visual effect. Not only will it easily cause visual numbness and dizziness when watching 3D polariz...

Problems solved by technology

[0003] Because the 3D visual effect of this method varies from person to person, many people may not be able to immediately see the 3D visual effect. Not only will it easily cause visual numbness and dizziness when watching 3D polarized movies through 3D glasses for a long time, resulting in wrong judgments, but also for the test. There are requirements for movies and pictures, and it is necessary to polarize the movie for the corresponding format. The test process cannot be fool-proof. Even if the tester does not see the 3D effect, he may easily let the machine pass through the test process.
