Abstract: In this paper, we try to extend human eyes’ contrast sensitivities characteristics (CSF) to three-dimensional space, but the experimental results show that the traditional characteristics of CSF has limitations in three-dimensional space. In order to investigate the characteristics of human eyes’ CSF in three-dimensional space, the traditional CSF test method is developed to measure the corresponding values of CSF in different inclined planes in three-dimensional space. Human visual contrast sensitivity characteristics with different inclined angles $$\theta $$ are analyzed, and the mathematical expression of $$\theta -CSF$$ is built up based on the experimental results. The proposed $$\theta -CSF$$ model of three-dimensional space in this paper can well reflects human visual contrast sensitivity characteristics in 3D space and has significant effect on three-dimensional image processing.
