[0091] refer to image 3 , the second embodiment of the present invention provides an eye tracking method, based on the above figure 2 In the first embodiment shown, the eye tracking method further includes:

[0092] Step S40, acquiring an image captured by a preset camera, where the number of the preset camera is one;

[0093] In the case of eye tracking through two cameras, since the two cameras work at the same time will increase the power consumption of the virtual reality device, this embodiment is only used when the accuracy of eye tracking based on images collected by a single camera is low In this case, eye tracking is further realized through images captured by more than two cameras, and when the images captured by a single camera can meet the accuracy requirements of eye tracking, eye tracking is performed on images captured by a single camera to reduce the cost of virtual reality equipment. power consumption.

[0094] The preset camera is a preset camera, and th...

Abstract

The invention discloses an eyeball tracking method and virtual reality equipment, the eyeball tracking method is applied to the virtual reality equipment, the virtual reality equipment comprises at least two cameras, and shooting areas of the cameras are partially overlapped. The eyeball tracking method comprises the following steps: acquiring images shot by at least two cameras at the same moment; overlapping overlapped areas in the images to obtain a target image including an eyeball area; and performing eyeball tracking according to the target image, so that the eyeball tracking accuracy can be improved.

Description

technical field [0001] The invention relates to the field of virtual reality equipment, in particular to an eye tracking method and virtual reality equipment. Background technique [0002] In order to achieve specific functions, the virtual reality device needs to track the user's eyeballs. When performing eyeball tracking, a camera with a larger field of view can be used to capture images containing the user's eyes, and further track the user's eyeballs. During eye tracking, the excessively large field of view causes distortion at the edge of the image captured by the camera, which makes eye tracking less accurate when the distorted image is used for eye tracking. Contents of the invention [0003] The main purpose of the present invention is to provide an eye tracking method and a virtual reality device, aiming at solving the technical problem of low eye tracking accuracy. [0004] In order to achieve the above object, the present invention provides an eye tracking meth...
