Embodiment 1

[0030] figure 1 It is a flow chart of the method for determining the position of the human eye provided in Embodiment 1 of the present invention. This embodiment is applicable to the determination of the position of the human eye. The method can be executed by a device for determining the position of the human eye. The device can use software and / or implemented in hardware. like figure 1 As shown, the method for determining the position of the human eye includes:

[0031] Step 110, calculate the initial positions of the left eye and the right eye according to the distance between the left eye and the right eye on the imaging plane of the camera.

[0032] In general, when calculating the position information of an object, it is usually selected to perform calculations in the coordinate system. Therefore, the embodiment of the present invention introduces a coordinate system for calculating the position of the left eye and the left eye, and subsequently calculating other posi...

Embodiment 2

[0063] Figure 10 It is a flow chart of the method for determining the position of human eyes provided by Embodiment 2 of the present invention. On the basis of Embodiment 1 above, this embodiment of the present invention further optimizes the steps of correcting the positions of the left and right eyes based on the head orientation. like Figure 10 As shown, the method for determining the position of the human eye includes:

[0064] Step 210, calculate the initial positions of the left eye and the right eye according to the distance between the left eye and the right eye on the imaging plane of the camera.

[0065] Step 220, calculate the center position of the head model according to the initial positions of the left eye and the right eye.

[0066] Step 230, calculate the head orientation based on the center position of the head model, the head orientation includes: the angle between the line between the center position of the head model and the center position of the scre...

Embodiment 3

[0093] Figure 11 It is a schematic structural diagram of the device for determining the human eye position provided in Embodiment 3 of the present invention. The device executes the method for determining the human eye position provided in any of the above embodiments, and the device can be implemented by software and / or hardware. like Figure 11 As shown, the human eye position determination device includes: left and right eye position estimation module 410, head model center calculation module 420, left and right eye position correction module 430 and left and right eye position determination module 440, wherein:

[0094] The left and right eye position estimation module 410 is configured to calculate the initial positions of the left eye and the right eye according to the distance between the left eye and the right eye on the imaging plane of the camera.

[0095] The head model center calculation module 420 is configured to calculate the center position of the head model ...

Abstract

The embodiment of the invention discloses a human eye position determining method and device. The method includes the following steps: estimating initial positions of a left eye and a right eye according to a distance between the left eye and the right eye on an imaging plane in a camera, calculating a center position of a head model according to the initial positions of the left eye and the righteye, calculating the head orientation according to the center position of the head model, correcting the positions of the left eye and the right eye according to the head orientation, returning to the operation of calculating the center position of the head model according to the positions of the left eye and the right eye until the currently-calculated head model orientation and the line-of-sight direction determined based on the positions of the left eye and the right eye meet preset errors, and determining the corresponding positions of the left eye and the right eye that meet the preset errors as the final human eye positions. According to the embodiment of the invention, the problem that the human eye positions can be accurately obtained by adopting a single camera can be solved, theconfiguration of a naked-eye 3D display can be reduced, the difficulty of design and production can be reduced, and the production cost of the naked-eye 3D display can be effectively saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of naked-eye 3D display, and in particular, to a method and device for determining human eye positions. Background technique [0002] Glasses-free 3D displays are widely used in various fields such as advertising, media, demonstration teaching, exhibition display, and film and television. Different from the traditional binocular 3D display technology, the naked-eye 3D display has the unique characteristics of the naked eye, that is, it does not require the audience to wear glasses or helmets to enjoy the 3D effect, and its realistic depth of field and stereoscopic effect greatly improve the audience The visual impact and immersion in the viewing experience have become the best display products for product promotion, publicity and video playback. [0003] The principle of naked-eye 3D display is generally to split the image displayed on the display through the lens. The lens refracts di...
