Data processing method and device

The embodiment of the invention provides a data processing method and device. The method mainly comprises the steps that first distance detected by a distance sensor is acquired, wherein the first distance is the distance between an eyeglass and the preset part of a human face; second distance is estimated according to the first distance, wherein the second distance is the distance between the pupil and the eyeglass; the optical focal distance is automatically regulated according to the second distance to enable a user to be capable of seeing a clear image, wherein the optical focal distance is the focal distance corresponding to an optical system composed of the pupil, the eyeglass, a watching screen and a rendered virtual image. Compared with the prior art, the data processing method and device have the advantage that the efficiency of regulating the optical focal distance in VR equipment can be improved.
