Description

Technical Field

[0001] The present application relates to the field of visual training, and particularly to a 3D display method, device and storage medium for 2D images. Background Art

[0002] Visual training is a training method for the eyes and the brain, which retrains the relationship between the brain and the eyes. Just like doing eye movements, this is a continuous stimulation and training of the brain's visual nerve cognitive system, increasing eye movement, focusing, fixation ability, and the cooperation ability of both eyes, visual processing ability, and treating visual functions such as amblyopia.

[0003] Binocular fusion phenomenon is a visual phenomenon. When both eyes observe the same object, the object forms an image on the respective retinas, and then is transmitted to the same area of the cortical visual center through the optic nerves on both sides, and is fused into a complete and single image perception experience. Generally speaking, when there are similar or related graphics, brightness, or color images in the two visual fields, binocular image matching and fusion are likely to occur. Otherwise, binocular diplopia, alternation of the two, or unilateral suppression often occur throughout the process.

[0004] Binocular vision refers to the vision of observing an object with both eyes at the same time. Although the two eyes form retinal images separately, normal binocular vision can fuse the two images into a single perceptual object. If the object observed by both eyes is a flat object, the two retinal images both fall on the corresponding points of the two retinas, and the positions of the corresponding points are the same; if the object observed by both eyes is a three-dimensional object, the retinal images of the two eyes are not exactly the same, forming binocular disparity and generating stereoscopic perception.

[0005] However, when converting a 2D image into a 3D image, due to the existence of the viewing angle, users can often only receive the view with one eye, and the other eye has no way to receive the view, resulting in an inability to view a clear 3D image and affecting the viewing effect. Summary of the Invention

[0062] The 3D display method, device, and storage medium for 2D images provided by the embodiments of this application can be applied to visual training, conventional 3D video processing, and personalized 3D display solutions.

[0063] The following will describe the 3D display method for 2D images provided by the embodiments of this application from the perspective of a terminal device. Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the 3D display method for 2D images provided by the embodiments of this application, including:

[0064] 101. Determine a first image and a second image corresponding to the target image.

[0065] In this embodiment, the terminal device can first obtain the target image, which is a 2D image to be 3D displayed. The target image can be an independent 2D image or each frame of 2D image in a video stream, and is not specifically limited. After obtaining the target image, the first image and the second image corresponding to the target image can be determined, that is, the 2D image is copied to obtain the first image and the second image.

[0066] 102. Determine the reference offset interval corresponding to the target user who views the 2D image for 3D display at a preset distance.

[0067] In this embodiment, the terminal device can determine the reference offset range corresponding to the target user who views the 3D image after 3D display at a preset distance (for example, the distance between the human eye of the target user and the display screen of the terminal device is 40 cm. Of course, it can also be other distances, which are not specifically limited). That is, different users have different reference offset ranges. The following is a detailed description: The method for determining the reference offset range corresponding to the target user

[0068] 1. The terminal device determines the reference offset range corresponding to the target user who views the 2D image after 3D display at a preset distance, including:

[0069] Determine the initial visual parameters corresponding to the target user;

[0070] Adjust the offset between the third image and the fourth image corresponding to the first test 3D image;

[0071] Record the actual visual parameters corresponding to the target user when the offset third image and fourth image are presented after blanking;

[0072] Determine the first maximum offset and the first minimum offset between the center of the third image and the center of the fourth image when the actual visual parameters match the initial visual parameters;

[0073] Determine the reference offset range according to the first maximum offset and the first minimum offset.

[0074] In this embodiment, the terminal device can first determine the initial visual parameters corresponding to the target user. The initial visual parameters are the initial visual parameters of the left eye and the right eye of the target user in a relaxed state (for example, they can be obtained by an eye tracker. Of course, they can also be obtained by other methods, which are not specifically limited). The initial visual parameters of the left eye are (x L0 , y L0 , r L0 ), and the initial visual parameters of the right eye are (x R0 , y R0 , r R0 ), and the binocular horizontal center difference visual parameter distance_x_eyes, where distance_x_eyes = |x L0 - x R0 |, x is the horizontal coordinate of the pupil, y is the vertical coordinate of the pupil, and r is the pupil radius. Here, the third image is taken as the image corresponding to the left eye, and the fourth image is taken as the image corresponding to the right eye for illustration.

[0075] After adjusting the offset between the third image and the fourth image, the first offset is obtained. It can be understood that adjusting the offset between the third image and the fourth image here can be to fix the third image and offset the fourth image in a direction away from the third image. Of course, it can also be to fix the fourth image and offset the third image in a direction away from the fourth image. Of course, it can also be to offset the third image and the fourth image in directions away from each other at the same time. The specific method is not limited. For the convenience of description, the following takes fixing the third image and offsetting the fourth image in a direction away from the third image to calculate the reference offset interval:

[0076] Offset the fourth image in a direction away from the third image, and record the offset change amount distance_x of the fourth image in a direction away from the third image. First, blank out the fourth image and the third image, and then present them, and record the actual visual parameters (x L1 , y L1 , r L1 ) corresponding to the target user after presentation and (x R1 , y R1 , r R1 ). Then, determine whether the initial visual parameters match the actual visual parameters (the method for determining whether the initial visual parameters match the actual visual parameters can be to determine whether the offset change amount distance_x is proportional to distance_x_eyes. If so, it is determined that they match. Of course, other methods can also be used, such as determining whether the difference between the actual visual parameters and the initial visual parameters is less than a preset value. If so, it is determined that they match. The specific method is not limited). If so, determine the offset between the center of the offset third image and the center of the fourth image as the extreme value of the reference offset interval (that is, a maximum or minimum value in the reference offset interval). If not, continue to offset the fourth image in a direction away from the third image on the basis of the offset change amount (the distance of each offset can be a preset distance), and repeat the above steps until the actual visual parameters corresponding to the target user match the initial visual parameters when the fourth image and the third image are blanked out and presented again. At this time, the offset between the center of the fourth image and the center of the third image is the extreme value of the reference offset interval. Repeat the above steps, fix the third image, offset the fourth image in a direction closer to the third image, and determine the other extreme value of the reference offset interval.

[0077] The following combines Figure 2 to illustrate the method for determining the reference offset interval. Figure 2Schematic diagram of an embodiment of the 3D display method for 2D images provided by the embodiments of the present application. Taking the third image fixed and the fourth image moving away from the third image to adjust the offset between the third image and the fourth image as an example, where 201 is the third image and 202 is the fourth image. The fourth image 202 is offset in a direction away from the third image 201 (such as Figure 2 the direction indicated by the arrow 203 in), and the offset distance is a preset distance. Then, the offset between the center 202A of the fourth image 202 and the center 201A of the third image 201 is recorded. At the same time, the fourth image 202 and the third image 201 are blanked out, and then presented again. The actual visual parameters corresponding to the target user when presented again are recorded. At the same time, it is determined whether the actual visual parameters match the initial visual parameters of the target user in the relaxed state. If so, the offset between the center 202A of the offset fourth image 202 and the center 201A of the third image 201 is determined as the extreme value of the reference offset interval. If not, on the basis of the offset, the fourth image 202 is offset again in a direction away from the third image 201, and the offset distance is also a preset distance (that is, each offset is based on a preset distance, which can be the same or different), and the above steps are repeated until the actual visual parameters corresponding to the target user match the initial visual parameters when the fourth image 202 and the third image 201 are blanked out and presented again. At this time, the offset between the center 202A of the fourth image 202 and the center 201A of the third image 201 is the extreme value in the reference offset interval.

[0078] Second, the terminal device determines the reference offset interval corresponding to the target user who views the 2D image after 3D display at a preset distance, including:

[0079] Offset at least one of the fifth image and the sixth image according to the operation instruction of the target user. The fifth image and the sixth image are the images corresponding to the second test 3D image;

[0080] If the recording instruction of the target user is received, record the second maximum offset and the second minimum offset between the center of the fifth image and the center of the sixth image according to the recording instruction;

[0081] Determine the reference offset interval according to the second maximum offset and the second minimum offset.

[0082] In this embodiment, the terminal device can display the second test 3D image and issue a prompt message for prompting the target user to offset at least one of the fifth image and the sixth image. After that, the target user can operate on the second standard test 3D image. The terminal device can receive the operation instruction of the target user and offset at least one of the fifth image and the sixth image according to the operation instruction of the user (the offset here can be that the sixth image remains fixed and the fifth image offsets away from the sixth image. Of course, it can also be that the fifth image remains fixed and the sixth image offsets away from the fifth image. Of course, it can also be that the fifth image and the sixth image offset away from each other at the same time, and the specific is not limited). Until the target user cannot perceive the 3D image formed by the fifth image and the sixth image in the brain, a recording instruction is issued. The terminal device records the offset amount between the center of the fifth image and the center of the sixth image according to the recording instruction of the target user. The offset amount between the center of the fifth image and the center of the sixth image is the extreme value in the reference offset interval. Repeat the above steps, fix the fifth image, offset the sixth image towards the fifth image, and determine the other extreme value of the reference offset interval.

[0083] It should be noted that through step 101, the first image and the second image corresponding to the target image can be determined. Through step 102, the reference offset interval corresponding to the target user of the 2D image after 3D display when viewed at a preset distance can be determined. However, there is no limit on the order of execution between these two steps. Step 101 can be executed first, step 102 can be executed first, or they can be executed simultaneously, and the specific is not limited.

[0084] 103. Periodically adjust the target offset amount between the first image and the second image within the reference offset interval.

[0085] In this embodiment, after the terminal device determines the reference offset interval and the first image and the second image corresponding to the target image, it can first determine the 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 within the reference offset interval.

[0086] It can be understood that the terminal device can periodically adjust the target offset amount within the reference offset interval through the following formula:

[0087] Δd = f(t);

[0088] Where Δd is the target offset amount, f(t) is a periodic continuous function, and this f(t) can be a cosine function, and t is a time variable. That is to say, the value of Δd, the direction and frequency of the change of the first image and the second image change with the change of this periodic continuous function.

[0089] It should be noted that the terminal device can determine the target offset in the following manner:

[0090] Determine a first offset between the position of the first image after adjustment and the position of the first image before adjustment;

[0091] Determine a second offset between the position of the second image after adjustment and the position of the second image before adjustment;

[0092] Determine the sum value of the first offset and the second offset as the target offset.

[0093] In this embodiment, when the terminal device detects the target offset between the first image and the second image after forming the 3D display image in real time, it can determine the first offset between the position of the first image after adjustment and the position of the first image before adjustment, determine the second offset between the position of the second image after adjustment and the position of the second image before adjustment, and determine the sum value of the first offset and the second offset as the target offset. Herein, "before adjustment" refers to the initial positions of the first image and the second image, and "after adjustment" refers to the actual positions of the first image and the second image when forming the 3D image after processing.

[0094] 104. Interleave the first image and the second image after adjusting the target offset to perform 3D display of the 2D image.

[0095] In this embodiment, after the terminal device adjusts the target offset each time, it can interleave the first image and the second image after adjusting the target offset to generate and display a 3D image.

[0096] In summary, it can be seen that in the embodiments provided by the present application, the terminal device can periodically adjust the target offset between the first image and the second image, so that the adjusted target offset is always within the reference offset interval, ensuring that both eyes of the user can receive views when watching the conversion of the 2D image into the 3D image, and thus a clear 3D image can be observed.
