Problems solved by technology

However, the 3D images displayed by the holographic display device in the prior art cannot be seen by the user at every position. There is an optimal viewing range no matter the angle or the distance. If it leaves this range, You can no longer enjoy clear 3D images

Embodiment approach

[0074] Different from the first embodiment, the holographic display method of this embodiment continues to track the human eye image after reducing the converted depth of field of the displayed 3D image, and determines the center position between the eyes and the viewer's viewpoint on the display screen. When the connection line of the specific position is perpendicular to the plane of the display screen, the converted depth of field of the displayed 3D image is increased, so that the displayed 3D image can restore the original display effect, so that the viewer can watch a clearer and more effective 3D image , to increase user experience.

[0075] In another embodiment, as Figure 6 as shown, Figure 6 It is a schematic flowchart of still another embodiment of the viewing angle-based adaptive holographic display method of the present invention.

[0076] The difference between this embodiment and the previous embodiment is that before performing step 606 of determining the c...

Abstract

The invention discloses a viewing angle-based adaptive holographic display method and a holographic display device. The viewing angle-based adaptive holographic display method comprises real-time tracking of a viewer's human eye image, and determining both eyes according to the human eye image. the center position between the two eyes; analyze the image of the human eye to determine the specific position of the viewer's viewpoint on the display screen; determine whether the line connecting the center position between the eyes and the specific position is consistent with the plane of the display screen vertical; and when the connecting line is not perpendicular to the plane of the display screen, reducing the converted depth of field of the displayed 3D image. In the above manner, the present invention enables the viewer to watch a clear 3D image at any position.

Description

technical field [0001] The present invention relates to the field of holographic display, in particular to a depth-of-field adaptive display method and a holographic display device based on the viewing angle of human eyes. Background technique [0002] To be able to see an object clearly, people generally need to locate the distance relationship of the actually seen object and be able to clearly obtain the image formed by the object on the retina. These two processes are generally called eyeball vergence and eyeball accommodation respectively. Eyeball accommodation is the process by which the eyeball obtains a clear image of an object by changing its focus. Eyeball convergence refers to the process of imaging an object on the retina at the center of the macula of both eyes, that is, the process of positioning the front and rear positions of the object or the depth of field with the eyes. [0003] On the basis of the above principles, the holographic display technology is i...
