Zusammenfassung:The invention discloses a system for quantitatively evaluating visual function. The method mainly solves the problem that the cooperation degree of testees is poor due to the fact that a conventional measurement method is greatly different from a daily visual task, time is consumed, and the measurement method is too boring. The invention provides a system for quantitatively evaluating a visual function. The system is used for comprehensively evaluating a spatial visual function and a corresponding time characteristic in a visual system. The system comprises the steps of Gaussian light spot tracking detection, time sequence cross correlation analysis, skewed Gabor fitting and the like, measurement of the spatial visual function and the corresponding time characteristic of a patient is achieved, and a measurement result map and related parameters are automatically generated. Compared with a traditional method, the system is closer to a daily visual task, the measurement efficiency is higher, meanwhile, the prob
