Abstract
The invention discloses an eyeball tracking device and method and near-to-eye display equipment. The eyeball tracking device comprises an optical assembly, a camera, a zoom lens, a light source and a control module, the optical assembly at least comprises a first lens group with focal power, the zoom lens and the camera are located on the side, away from human eyes, of the first lens group, the zoom lens is located between the first lens group and the camera, light emitted by the light source enters the human eyes, and light reflected by the human eyes enters the camera after being transmitted by the first lens group and the zoom lens; the zoom lens and the camera are both connected with the control module, and the control module is used for adjusting the surface shape of the zoom lens to compensate aberration caused by the first lens group and realizing eyeball tracking according to an image acquired by the camera. According to the eyeball tracking device provided by the invention, the image quality can be adjusted by adjusting the surface shape of the zoom lens before leaving a factory or in real time, and the eyeball tracking accuracy can be greatly improved.
