Abstract

Embodiments of the present invention provide a gaze point compensation method for a display device, a compensation device, and a display device, which relate to the technical field of intelligent display devices and can solve the problem of eye tracking accuracy caused by relative sliding between the human eye and the VR headset in the prior art. drop problem. The method includes: obtaining the user's real-time eye image; obtaining the eye corner position coordinates of the real-time eye image; if the eye corner position coordinates are within the initial calibration range, performing a first compensation for the eye corner position coordinates according to the corresponding relationship between the pupil and the eye corner position ; If the eye corner position coordinates are not within the initial calibration range, perform a second compensation on the eye corner position coordinates, and the second compensation is configured to make the eye corner position coordinates after the second compensation at least within the initial calibration range; according to the first compensation or the second compensation The second compensation compensates for the point of gaze. The present invention is used in a display device.

Description

technical field [0001] The present invention relates to the technical field of intelligent display devices, in particular to a gaze point compensation method of a display device, a compensation device, and a display device. Background technique [0002] With the development of virtual reality (Virtual Reality, VR) technology, the application of eye tracking technology in virtual reality interaction, foveated rendering and other aspects has also received attention. At present, in the VR-based eye tracking system, the camera used to capture the eye movement is located in the VR head-mounted display. Since the human eye and the VR head-mounted display are two relatively independent individuals, when the VR head-mounted display is used, the human eye may Sliding relative to the VR head-mounted display will cause the eye tracking system to deviate from the initial calibration position, resulting in a decrease in eye tracking accuracy. Contents of the invention [0003] Embodim...
