Embodiment 1

[0063] attached Figure 1-4 , 13-14 is a flowchart of a human eye tracking method for a naked-eye 3D device provided by the present invention, including the following steps:

[0064] 100: Obtain the face image in the user's image, and obtain the coordinates of the midpoint of both eyes in the face image. Such as Figure 5 As shown, the camera captures the image of the object in the front imitation cone-shaped space. First, it needs to obtain the image containing the user's face. Generally, the obtained image or image data is in yuv format, and it is converted into a general rgb for image recognition. format, using face recognition technology to recognize the face image, and recognize the midpoint of the eyes in the face image, and obtain the coordinates of the midpoint of the eyes in the image.

[0065] After obtaining the face image in the user's image, it generally includes:

[0066] 101: Obtain the distance between the eyes in the face image. Use face recognition techno...

Embodiment 2

[0087] Such as Figure 10 Shown is a structural block diagram of a human eye tracking device for a naked-eye 3D device provided by the present invention, which is used to implement the method in the first embodiment above, including a camera 500, a processor 600, and a rotating device 700. The naked-eye 3D device is fixed on a rotating on the device. The processor 600 is used to obtain the coordinates of the midpoint of the eyes in the face image, determine that the coordinates of the midpoint of the eyes fall outside the preset target area in the image, and send a rotation instruction to the rotation device 700, and the rotation device 700 is used to receive the rotation instruction. Drive the naked-eye 3D device and the camera to rotate, so that the coordinates of the midpoint of the eyes fall into the target area.

[0088] The camera 500 may be a front camera installed on the naked-eye 3D device, or may be a camera fixed on a rotating device that rotates together with the ...

Embodiment 3

[0103] Figure 11 It is a structural block diagram of a human eye tracking device for a naked-eye 3D device provided by the present invention, only the first instruction sending module 602 in Embodiment 2 is replaced by an angle calculation module 620 and a second instruction sending module 621 .

[0104] The angle calculation module 620 is used to calculate the second rotation angle required for the naked-eye 3D device to rotate to the rotation direction to reach the target area according to the coordinates of the midpoint of the eyes. For specific calculation, see step 303 in the first embodiment.

[0105] The second instruction sending module 621 is used for sending the second rotation instruction including the rotation direction and the second rotation angle to the rotation device.

[0106] After receiving the second rotation instruction, the rotation device 700 rotates the naked-eye 3D device and the camera to the rotation direction by the second rotation angle. In the s...

Abstract

The invention relates to a human eye tracking method and device of naked eye 3D equipment. The human eye tracking method comprises the steps of obtaining the human face image of a user and obtaining the coordinate of the middle point of two eyes in the human face image; determining the coordinate of the middle point of the two eyes to be out of a preset target area in the image, which is arranged between a preset 3D left image visual area and a 3D right image visual area in the image; rotating the naked eye 3D equipment, to ensure that the coordinate of the middle point of the two eyes to be within the target area. The method and the device solve the problem that a user is difficult to find out and keep eyes to be within an optimum visual angle range when using the naked eye 3D equipment, ensures that the user within a visual distance range is not required to deliberately find out or keep a watching angle, eradicates feelings of dizziness and serious crosstalk, and ensures that the user can easily experience ideal 3D effect.

Description

technical field [0001] The invention relates to the technical field of human eye tracking, in particular to a human eye tracking method and device for a naked-eye 3D device. Background technique [0002] The current mainstream 3D stereoscopic display technology applied to equipment includes polarized light and shutter type, which cannot free us from the shackles of special glasses, which makes its application range and use comfort compromised. It will make long-time experiencers feel uncomfortable. Therefore, the driving force for the sustainable development of 3D stereoscopic display falls on the cutting-edge technology of naked-eye 3D display technology. Currently, the mainstream technology of glasses-free 3D mainly adopts parallax barrier technology and lenticular lens technology to achieve the effect of 3D images when viewing text and pictures without using special glasses. The light barrier (grating) and lenticular lens technologies are currently on the market with a ...
