Problems solved by technology

[0004] However, the 3D images displayed by the holographic display devices in the prior art are not clear 3D images that users can see at every position, and there is an optimal viewing range. If they leave this range, they will no longer be able to appreciate to clear 3D images
In addition, when the external light changes, such as when the light becomes dark, the camera is blocked or the camera is damaged, etc., the existing holographic display device can no longer meet the needs of users.

Embodiment approach

[0088] 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 after the human eye image is tracked, the two eyes are determined according to the tracked human eye image. Coordinates, and increase the converted depth of field of the displayed 3D image, 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, increasing user experience.

[0089] In another embodiment, as Figure 5 As shown, 5 is a schematic flowchart of another embodiment of the holographic display method based on human eye tracking in the present invention.

[0090] The difference between this embodiment and the previous embodiment is that before performing step 505 to determine the coordinates of both eyes according to the tracked human eye image, and increase the converted depth of fi...

Abstract

The invention discloses a holographic display method and a holographic display device based on eye tracking. The holographic display method comprises the following steps: tracking the eyes of a viewer in real time, and acquiring an eye image; judging whether eye coordinates can be determined or not according to the tracked eye image; and when the eye coordinates cannot be determined according to the tracked eye image, reducing the conversion depth of field of a displayed 3D image. Through the way, a user can still view a clear 3D image when eye positions cannot be tracked clearly by a camera.

Description

technical field [0001] The present invention relates to the field of holographic display, in particular to a holographic display method and a holographic display device based on human eye 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] When people watch the images played by the holographic display, in order to enable the human eye to ob...
