According to the refractive pattern generation method and device based on the light field, the equipment and the storage medium provided by the embodiment of the invention, the light field information at the fundus conjugate surface of the to-be-detected human eye is acquired, and the light field information is acquired when the light field camera shoots the fundus image of the to-be-detected human eye; based on the light field information, calculating depth information of the fundus conjugate surface of the to-be-measured human eye; on the basis of the depth information, refraction information of the fundus of the human eye to be measured is obtained; and based on the refraction information, generating a refraction pattern of the to-be-measured human eye. According to the method, the to-be-measured eye fundus image is shot once through the light field camera, the refraction information of the to-be-measured eye is obtained through an algorithm, and the refraction graph is generated through the refraction inf
