Description
Technical Field

Background
The vision training is a training mode of eyes and brain, retrains the relation between the brain and the eyes, and is used for continuously training the stimulation and the training of a brain vision neurocognitive system, increasing the eye movement, focusing, vision fixing capacity, the cooperative capacity of the eyes, the vision processing capacity, the visual function of treating amblyopia and the like doing eye movement.
The binocular fusion phenomenon is a visual phenomenon, when two eyes observe the same object, the object of the object image is formed on the retinas of the two eyes, and then the object is transmitted to the same area of the visual center of the cortex layer through the optic nerves on the two sides respectively, so that the two eyes are fused into a complete and single perception experience of the object image. Generally, binocular visual matching fusion occurs easily when two views have similar or related images, brightness or color, or else the entire process tends to be binocular diplopia, both alternate or unilateral suppression.
Binocular vision refers to vision in which both eyes observe an object at the same time. Although the two eyes form retinal images separately, normal binocular vision can fuse two views into a single perceptual object. If the two eyes observe a plane object, the two retina images are both located at corresponding points of the retinas of the two eyes, and the corresponding points are the same; if the two eyes observe a three-dimensional object, the retina images of the two eyes are not identical, so that binocular parallax is formed, and three-dimensional perception is generated.

And repeatedly executing the steps, fixing the third image, shifting the fourth image to the direction close to the third image, and determining the other extreme value of the reference shifting interval.
Referring to fig. 2, a manner of determining a reference offset interval is described, where fig. 2 is a schematic view of an embodiment of a method for 3D displaying a 2D image according to an embodiment of the present application, where a third image is fixed, a fourth image is moved away from the third image to adjust an offset between the third image and the fourth image, where 201 is the third image, 202 is the fourth image, the fourth image 202 is offset (in a direction indicated by an arrow 203 in fig. 2) in a direction away from the third image 201, the offset is a preset distance, then an offset between a center 202A of the fourth image 202 and a center 201A of the third image 201 is recorded, the fourth image 202 and the third image 201 are blanked, then the third image is re-rendered, and an actual visual parameter corresponding to a target user when the second image is re-rendered is recorded, and whether the actual visual parameter matches the initial visual parameter of the target user in a relaxed state is recorded, if so, determining the offset amount between the center 202A of the shifted fourth image 202 and the center 201A of the third image 201 as an extreme value of the reference offset interval, if not, shifting the fourth image 202 again in a direction away from the third image 201 on the basis of the shifted fourth image, the shifted distance being the same as the preset distance (that is, each shift may be the same or different according to the preset distance), and repeating the above steps until the actual visual parameter corresponding to the target user matches the initial visual parameter when the fourth image 202 and the third image 201 are displayed again after being blanked, where at this time, the offset amount between the center 202A of the fourth image 202 and the center 201A of the third image 201 is the extreme value of the reference offset interval.
Secondly, the step that the terminal equipment determines a reference offset interval corresponding to a target user who watches the 2D image after the 3D display at a preset distance comprises the following steps:
shifting at least one of a fifth image and a sixth image according to an operation instruction of a target user, wherein the fifth image and the sixth image are images corresponding to the second test 3D image;
if a recording instruction of the target user is received, recording a second maximum offset and a second minimum offset between the center of the fifth image and the center of the sixth image according to the recording instruction;
and determining the reference offset interval according to the second maximum offset and the second minimum offset.
In this embodiment, the terminal device may display the second test 3D image and send a prompt message, where the prompt message is used to prompt the target user to shift at least one of the fifth image and the sixth image, and then the target user may operate the second standard test 3D image, and the terminal device may receive an operation instruction of the target user and shift at least one of the fifth image and the sixth image according to the operation instruction of the user (where the shift may be that the sixth image is kept fixed, the fifth image is shifted in a direction away from the sixth image, and of course, the fifth image is kept fixed, and the sixth image is shifted in a direction away from the fifth image, and of course, the fifth image and the sixth image are simultaneously shifted in a direction away from each other, and is not limited specifically) until the target user cannot perceive that the fifth image and the sixth image form the 3D image in the brain, and sending a recording instruction, and recording the offset between the center of the fifth image and the center of the sixth image by the terminal equipment according to the recording instruction of the target user, wherein the offset between the center of the fifth image and the center of the sixth image is an extreme value in the reference offset interval. And repeatedly executing the steps, fixing the fifth image, shifting the sixth image to the direction close to the fifth image, and determining the other extreme value of the reference shifting interval.
It should be noted that, the step 101 may determine the first image and the second image corresponding to the target image, and the step 102 may determine the reference offset interval corresponding to the target user who views the 2D image after 3D display at the preset distance, however, there is no sequential execution order limitation between the two steps, and the step 101 may be executed first, or the step 102 may be executed first, or executed simultaneously, which is not specifically limited.
103. And periodically adjusting the target offset between the first image and the second image in a reference offset interval.
In this embodiment, after determining the reference offset interval and the first image and the second image corresponding to the target image, the terminal device may first determine a target offset amount between the first image and the second image, and periodically adjust the target offset amount between the first image and the second image in the reference offset interval.
It can be understood that the terminal device may periodically adjust the target offset amount in the reference offset interval by the following formula:
Δd＝f(t)；
where Δ d is the target offset, f (t) is a periodic continuous function, f (t) may be a cosine function, and t is a time variable. That is, the value of Δ d, the direction and frequency of the change in the first and second images varies as the periodic continuous function varies.
It should be noted that the terminal device may determine the target offset by:
determining a first offset between the position of the adjusted first image and the position of the first image before adjustment;
determining a second offset between the position of the adjusted second image and the position of the second image before adjustment;
the sum of the first offset amount and the second offset amount is determined as a target offset amount.
In this embodiment, when detecting a target offset between a first image and a second image after forming a 3D display image in real time, the terminal device may determine a first offset between a position of the first image after adjustment and a position of the first image before adjustment, determine a second offset between a position of the second image after adjustment and a position of the second image before adjustment, and determine a sum of the first offset and the second offset as the target offset, where the first image and the second image are at initial positions before adjustment, and the first image and the second image are at actual positions when the 3D image is formed after processing.
104. And interleaving the first image and the second image after the target offset is adjusted so as to display the 2D image in a 3D mode.
In this embodiment, after adjusting the target offset amount each time, the terminal device may interleave the first image and the second image after adjusting the target offset amount to generate and display a 3D image.
In summary, it can be seen that, in the embodiment provided by the application, the terminal device may periodically adjust the target offset between the first image and the second image, so that the adjusted target offset is always located between the reference offset intervals, and it is ensured that both eyes of a user can receive a view when watching a 2D image converted into a 3D image, and then the user can observe a clear 3D image.
