Abstract: An eyeball tracking method and a virtual reality device are disclosed. The eyeball tracking method is applied to the virtual reality device, the virtual reality device comprises at least two cameras, and shooting areas of the cameras are partially overlapped. The eyeball tracking method comprises the steps of: acquiring images captured by at least two cameras at a same moment; superimposing overlapping areas in the images to obtain a target image including an eyeball area; and performing eyeball tracking according to the target image. The accuracy of eyeball tracking can be improved.

Abstract: An imaging method of a head-mounted display and a head-mounted display are disclosed. The method includes, but is not limited to: detecting a wavefront of a beam emitted by the head-mounted display through its optical system; acquiring a position of a visual axis of a human eye; calculating a deviation between the visual axis of the human eye and an optical axis of the optical system; and adjusting a wavefront incident to the human eye according to the deviation, so that a correspondence between the wavefront incident to the human eye and the visual axis is consistent with a correspondence between the wavefront of the beam emitted from the optical system and the optical axis.
