Abstract: The measurement of traditional image crosstalk degrees needs precision optical instruments, which has a high requirement on the environment light and also causes a complex data processing. This paper proposes a new binocular image crosstalk degree detection method based on the human eye observation combined with the brightness scale. First, the test pattern is generated and used for crosstalk degrees detection. Then, the equivalent visual brightness principles are used to select the best observation position. Finally, the selective matching between the crosstalk area and the brightness scale are used to estimate the crosstalk degrees. The experiment results show that the test results of the proposed method is the same as the test results of HIS color model. It can accurately describe the degrees of crosstalk of the grating type auto-stereoscopic display system. At the same time, the test results of the proposed method is not affected by the light of the experiment, which proves that the proposed method is strong robust for the testing environment.
