A distance adaptive holographic displaying method and device based on eyeball tracking are disclosed. The method includes: detecting a human face of a user and acquiring positions of eyes of the user, wherein the positions of the eyes of the user comprise a distance between the eyes and a displaying screen; adjusting the size of an object in a holographic scene along a z-axis direction in the holographic three-dimensional display according to the distance, and displaying the object in the displaying screen; adjusting an emergent direction of the light emitted by the displaying screen to the direction of the left eye and the right eye of the eyes so that the different individual holographic three-dimensional images of the left eye and the right eye are imaged into the left eye and the right eye respectively; and tracking the change of the positions of the eyes, and repeating the aforesaid steps to dynamically adjust viewpoints and the displayed content. The present disclosure can adapt to different groups of people at different distances and conform to the visual principle of human beings, thereby improving user experiences.

Distance adaptive holographic displaying method and device based on eyeball tracking

A method and an apparatus for achieving transformation of a virtual view into a 3D view are provided. The method comprises: S. capturing position coordinates of a human eye by a human-eye tracking module; S. determining a rotation angle of a virtual scene and rotating the virtual scene according to the rotation angle to obtain a virtual holographic 3D view matrix by a first image processing module; S. determining a shearing angle for each of viewpoints to generate a shearing matrix for the viewpoint in one-to-one correspondence, and post-multiplying the shearing matrix with a corresponding viewpoint model matrix to generate a left view and a right view by a second image processing module; and S. projecting the left view and the right view of each of the viewpoints by the projection displaying module.
