Gaze point compensation method and compensation device of display device and display device

Abstract

The embodiment of the invention provides a gaze point compensation method and device of a display device and the display device, which relate to the technical field of intelligent display equipment, and can solve the problem that in the prior art, eye tracking precision is reduced due to the fact that human eyes and a VR head display relatively slide. The method comprises the steps of obtaining areal-time eye image of a user; obtaining eye corner position coordinates of the real-time eye image; if the eye corner position coordinates are within the initial calibration range, carrying out firstcompensation on the eye corner position coordinates according to the corresponding relation between pupils and eye corner positions; if the eye angle position coordinates are not in the initial calibration range, performing second compensation on the eye angle position coordinates, the second compensation being configured to enable the eye angle position coordinates after the second compensationto be at least in the initial calibration range; and compensating the fixation point according to the first compensation or the second compensation. The method is used for the 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.
