Embodiment approach

[0072] 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 connection between the center position between the two eyes and the center point of the display screen. When the line is perpendicular to the plane of the display screen, the converted depth of field of the displayed 3D image is increased to restore the original display effect of the displayed 3D image, so that the viewer can watch a clearer and more effective 3D image and increase user experience.

[0073] In another embodiment, as Image 6 as shown, Image 6 It is a schematic flowchart of another embodiment of the adaptive holographic display method based on human eye image tracking in the present invention.

[0074] The difference between this embodiment and the previous embodiment is that, before performing step 605 of determining the coordinates of bot...

Abstract

The invention discloses a self-adaptive holographic display and a holographic display device based on human eye image tracking. The method comprises the following steps: tracking a human eye image of a watcher in real time and determining the central position between two eyes according to the human eye image; judging whether the connecting line of the central position between the two eyes and the central point of the display screen is vertical to the plane of a display screen or not; when the connecting line is not vertical to the plane of the display screen, reducing a conversion depth of field of displayed 3D images. Through above manner, according to the method and device disclosed by the invention, the watcher in any positions can watch the clear 3D images.

Description

technical field [0001] The present invention relates to the field of holographic display, in particular to an adaptive holographic display method and a holographic display device based on human eye image tracking. 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 invented, ...
