In this paper, it tries to extend the characteristics of human eyes' contrast sensitivity CSF) into (3D) space, but the experimental results show that the traditional characteristics of CSF have limitations in 3D space for lack of depth information. In order to investigate the characteristics of CSF in 3D space, traditional CSF tests are further developed to measure the corresponding properties of CSF with different inclined planes, and describe the oee integral-C S F characteristics of human eyes based on the inclined angles oee integral. According to the tests, the mathematical expression of oee integral-C S F is built up. In addition, the concept of spatial frequency in the direction of depth (f (D) ) is proposed, and f (D) -C S F characteristic surface is also achieved. The proposed 3D CSF has significant effects on the research of human visual characteristics and 3D image processing.
