Description

Technical Field

[0001] The present invention relates to the technical field of image processing, and in particular to a binocular fusion vision function training method and device. Background Art

[0002] Binocular vision is the process of projecting a single object from the outside world to both eyes, and then integrating it into a three-dimensional image through the visual center of the brain. It allows the brain to fuse the images observed by both eyes into a complete impression with three-dimensional perception, rather than two separate objects. Binocular vision function can be divided into three levels, namely simultaneous vision, fusion vision and stereoscopic vision. The normal three-level vision function is the basis for binocular perception of the shape and spatial position of objects, and is also an important prerequisite for various visual activities. Simultaneous vision (primary visual function) means that both eyes can see an object at the same time, and the image received by each eye just falls on the macula of the retina. After being transmitted to the brain, it is perceived as an image. It is the basis of binocular vision function and reflects whether the correspondence between the macula and the retina of both eyes is normal. Only when the simultaneous vision function is normal can fusion vision and stereoscopic vision be further established. Fusion vision (secondary visual function) is based on the normal simultaneous perception of both eyes. Through the analysis and processing of the brain, two images with slight differences from the corresponding points of the retinas of both eyes can be fused into a complete image. It reflects the brain's ability to integrate binocular images. Only when the fusion vision function is normal can a complete and clear object be seen, rather than two ghost or blurred images. Normal fusional vision is the basis for establishing stereoscopic vision (tertiary visual function). Myopic people often have convergence insufficiency due to delayed accommodation, and binocular fusion function may be abnormal, which can easily lead to symptoms of visual fatigue and even develop strabismus (exotropia). At the same time, convergence insufficiency can also lead to abnormal accommodation, which may accelerate the progression of myopia. Abnormal fusional vision can also cause abnormal stereoscopic vision, which reduces or loses depth perception and makes it impossible to accurately judge the distance and size of objects, thereby affecting daily activities such as walking and grasping objects, resulting in restricted life, driving safety hazards and limited career choices. Therefore, establishing normal binocular fusional vision is of great significance to visual health.

[0003] In the prior art, most of them are realized by installing fusion training software on the computer and cooperating with corresponding training equipment, and binocular dichotomy can be realized by several means. One is to use red-blue color difference 3D glasses or polarized light 3D glasses, and the eyes can only see the corresponding content on the screen through the corresponding lenses to realize binocular dichotomy; the other is to realize binocular dichotomy by displaying different contents on the left and right eye screens such as virtual reality and naked eye 3D. During training, the contents of the left and right eyes move towards or away from each other to guide the eyes to perform fusion range training. However, the red and blue glasses in the first method do not filter the images thoroughly based on different colors, and there is a problem of poor dichotomy effect. At the same time, the fusion range parameters in both methods are fixed and cannot be adjusted according to the actual situation of the user. The unfixed distance between the eyes and the computer also leads to uncertainty of the range parameters, which leads to the problem of low matching degree. In addition, since the initial position of the training screen is a fixed center position, the binocular images cannot be effectively fused when used by strabismic users, and the fusion starting point and the eye position do not match, resulting in poor final training effect.

[0004] In view of this, it is necessary to improve the binocular fusion training method in the prior art to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to disclose the problems that the existing binocular fusion training method has poor dichographic effect, and the fusion parameters are fixed and the matching degree is not high, and the initial position of the training picture is a fixed center position, and the binocular pictures cannot be effectively fused when used by strabismic users, and the final training effect is poor due to the mismatch between the fusion starting point and the eye position.

[0006] To achieve the above object, the present invention provides a binocular fusion vision function training method, comprising:

[0007] Acquire initial eye positions corresponding to both eyes of the user, where the initial eye positions refer to the position coordinates of the image in the corresponding display area when both eyes respectively observe the image displayed in the corresponding display area and align them;

[0008] Based on the initial eye positions of the user's eyes, respectively, horizontally adjust and vertically adjust the horizontal position and vertical position of the image in the corresponding display area to determine the horizontal fusion range and vertical fusion range of the user's eyes;

[0009] Within the horizontal fusion range and the vertical fusion range, images displayed in display areas corresponding to the user's two eyes are horizontally moved and vertically moved from the initial eye position to perform binocular fusion vision function training for the user.

[0010] As a further improvement of the present invention, the step of obtaining initial eye positions corresponding to both eyes of the user includes:

[0011] Get a test image;

[0012] Splitting the test image into a first test image and a second test image with completely different contents, and displaying them in display areas corresponding to the user's eyes respectively;

[0013] The positions of the first test image and the second test image in the corresponding display areas are adjusted respectively. When the user's two eyes respectively observe the first test image and the second test image displayed in the corresponding display areas and align them to form the test image, the position coordinates of the first test image and the second test image in the corresponding display areas are used as the initial eye positions corresponding to the user's two eyes respectively.

[0014] As a further improvement of the present invention, the steps of respectively adjusting the positions of the first test image and the second test image in the corresponding display areas include:

[0015] Keeping the position of the first test image in the corresponding display area unchanged, and adjusting the position of the second test image in the corresponding display area;

[0016] or,

[0017] Keeping the position of the second test image in the corresponding display area unchanged, adjusting the position of the first test image in the corresponding display area;

[0018] or,

[0019] The positions of the first test image and the second test image in the corresponding display area are adjusted simultaneously.

[0020] As a further improvement of the present invention, before horizontally adjusting and vertically adjusting the horizontal position and vertical position of the image in the corresponding display area based on the initial eye positions corresponding to both eyes of the user, the method includes:

[0021] Get a test image;

[0022] The test image is subjected to deletion processing to form a third test image and a fourth test image with different parts of content missing, and the third and fourth test images are displayed in display areas corresponding to the user's eyes, respectively.

[0023] As a further improvement of the present invention, the horizontal adjustment and vertical adjustment of the horizontal position and vertical position of the image in the corresponding display area based on the initial eye positions corresponding to the user's eyes respectively, so as to determine the horizontal fusion range and vertical fusion range of the user's eyes, includes:

[0024] Based on the initial eye position, the horizontal position of the image in the corresponding display area is adjusted horizontally at the same time until the images displayed in the corresponding display area are observed independently by both eyes of the user, and the horizontal movement distance of the image in the corresponding display area is determined as the horizontal fusion range of both eyes of the user;

[0025] Based on the initial eye position, the vertical position of the image in the corresponding display area is vertically adjusted simultaneously until the user's two eyes observe the images displayed in the corresponding display area independently, and the vertical movement distance of the image in the corresponding display area is determined as the vertical fusion range of the user's two eyes.

[0026] As a further improvement of the present invention, the adjusting the horizontal position of the image in the corresponding display area based on the initial eye position level includes:

[0027] The third test image and the fourth test image move in opposite directions at the same speed from the initial eye position level in the corresponding display area until the user's eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the first horizontal movement distances corresponding to the third test image and the fourth test image respectively;

[0028] The third test image and the fourth test image move in opposite directions at the same speed from the initial eye position level in the corresponding display area until the user's eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the second horizontal movement distances corresponding to the third test image and the fourth test image respectively;

[0029] The first horizontal movement distance and the second horizontal movement distance define a horizontal fusion range of the user's eyes.

[0030] As a further improvement of the present invention, the vertically adjusting the vertical position of the image in the corresponding display area based on the initial eye position includes:

[0031] The third test image and the fourth test image move vertically and backward from the initial eye position at the same speed in the corresponding display area until the user's eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the vertical movement distances corresponding to the third test image and the fourth test image respectively;

[0032] The vertical fusion range of the user's eyes is defined by the vertical movement distance between the third test image and the fourth test image.

[0033] As a further improvement of the present invention, the images displayed in the display areas corresponding to the user's eyes respectively moving horizontally and vertically from the initial eye position within the horizontal fusion range and the vertical fusion range include:

[0034] Acquire a first training image and a second training image for training, and display them in display areas corresponding to the user's eyes respectively;

[0035] When training the user's ability to spread both eyes horizontally, the first training image and the second training image are cyclically moved horizontally backwards from the corresponding initial eye positions based on the first horizontal movement distance;

[0036] When training the user's binocular horizontal convergence ability, the first training image and the second training image are cyclically moved horizontally opposite to each other from the corresponding initial eye positions based on the second horizontal movement distance;

[0037] When training the user's binocular vertical fusion ability, the first training image and the second training image are cyclically moved vertically backward from the corresponding initial eye positions based on the vertical movement distance;

[0038] As a further improvement of the present invention, the movement mode of the first training image and the second training image is stepless smooth movement or jump movement.

[0039] As a further improvement of the present invention, it also includes:

[0040] The initial eye positions corresponding to the user's eyes are respectively acquired within a set time and the horizontal fusion range and the vertical fusion range of the user's eyes are determined for updating.

[0041] Based on the same inventive concept, the present invention also discloses a binocular fusion vision function training device, comprising:

[0042] An acquisition module, wherein the acquisition module acquires initial eye positions corresponding to both eyes of the user, wherein the initial eye positions refer to position coordinates of the image in the corresponding display area when both eyes observe the image displayed in the corresponding display area and align the image;

[0043] A determination module, wherein the determination module horizontally adjusts and vertically adjusts the horizontal position and the vertical position of the image in the corresponding display area based on the initial eye positions corresponding to the user's eyes, respectively, to determine the horizontal fusion range and the vertical fusion range of the user's eyes;

[0044] A training module, wherein the training module horizontally moves and vertically moves the images displayed in the display areas corresponding to the user's two eyes respectively from the initial eye position within the horizontal fusion range and the vertical fusion range, so as to perform binocular fusion vision function training for the user.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] Before the binocular fusion vision function training is performed on the user's eyes, the initial eye positions corresponding to the user's eyes are first obtained, and the position coordinates of the images in the corresponding display areas are determined based on the alignment of the images displayed by the two eyes in the corresponding display areas. Therefore, whether it is a normal eye position or an abnormal eye position (for example, a strabismus eye position), the corresponding initial eye position can be determined according to the specific binocular situation. At the same time, the horizontal fusion range and the vertical fusion range of the user's eyes are determined based on the initial eye position, and binocular fusion vision function training is subsequently performed based on the initial eye position and the horizontal fusion range and the vertical fusion range to improve the matching degree between the initial eye position and the user's eyes, thereby solving the problems of poor separation effect in the existing binocular fusion training method and low matching degree due to the fixed fusion parameters, as well as the problem that the initial position of the training picture is a fixed center position, the binocular pictures cannot be effectively fused when used by a strabismus user, and the final training effect is poor due to the mismatch between the fusion starting point and the eye position.

[0055] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0056] Ginseng Figures 1 to 7 As shown, the present invention shows a binocular fusion vision function training method (hereinafter referred to as the "method"), which can be run on a fusion training software installed on a computer or wearable smart glasses, and is used to train the user's binocular fusion vision function to enhance and improve the coordination and visual function of the two eyes, promote the user's eye coordination and binocular fusion ability, and thus improve the visual effect.

[0057] Ginseng Figure 1 As shown, the method specifically includes the following steps S1 to S3.

[0058] Step S1: Obtain the initial eye positions corresponding to the user's eyes respectively.

[0059] Specifically, the initial eye position refers to the position coordinates of the test image in the corresponding display area when the images displayed in the corresponding display areas observed by both eyes are aligned. When the light signal of a single object in the outside world is transmitted to both eyes respectively, it will be fused to form a three-dimensional image after passing through the visual center of the brain. The brain will fuse the images observed by both eyes into a whole, rather than two separate objects. Therefore, when obtaining the initial eye positions corresponding to the user's eyes, in order to prevent the two eyes from interfering with each other and ensure the accuracy of the test, the user's binocular fusion state is broken, and the user's eyes observe different display areas respectively to achieve binocular vision, and the images displayed in different display areas have completely different contents. Based on this, when the images displayed in the corresponding display areas observed by both eyes are aligned (that is, when the aforementioned fusion is formed into a whole), the position coordinates of the image in the corresponding display area are used as the initial eye positions corresponding to the two eyes. For example, the fusion training software can be a VR version of the fusion training software, and binocular vision is achieved by displaying different contents on the left and right eye screens.

[0060] It should be noted that the alignment of the images displayed by the two eyes in the corresponding display areas refers to the combination of two images with completely different contents to form a complete image. The specific alignment method may be to align the centers of the two images, or to align the sides of the two images, etc. This embodiment does not specifically limit this. Figure 3Taking the lion inside the cage shown in the figure as an example, the central alignment of the two images means that the display area corresponding to the left eye only shows the cage, and the display area corresponding to the right eye only shows the lion. The user observes the images shown in the two display areas with their left and right eyes respectively. When the lion is inside the cage, that is, the center of the cage is aligned with the center of the lion, the position coordinates of the left-eye image in the corresponding display area and the position coordinates of the right-eye image in the corresponding display area are used as the initial eye positions corresponding to the user's two eyes. The side alignment of the two images means that the display area corresponding to the left eye shows half of the cage and half of the lion, and the display area corresponding to the right eye shows the other half of the cage and the other half of the lion. The user observes the images shown in the two display areas with their left and right eyes respectively. When the lion and the cage are both complete and the lion is inside the cage, that is, the sides of the two images are aligned, the position coordinates of the left-eye image in the corresponding display area and the position coordinates of the right-eye image in the corresponding display area are used as the initial eye positions corresponding to the user's two eyes.

[0061] In this application, before performing binocular fusion vision function training on the user's two eyes, the initial eye positions corresponding to the user's two eyes are first obtained, and specifically determined based on the position coordinates of the images in the corresponding display areas when the images shown in the corresponding display areas observed by the two eyes are aligned. Therefore, whether it is a normal eye position or an abnormal eye position (for example, a strabismus eye position), the corresponding initial eye position can be determined according to the specific binocular situation. At the same time, the horizontal fusion range and vertical fusion range of the user's two eyes are determined based on the initial eye positions, and subsequent binocular fusion vision function training is performed based on the initial eye positions, the horizontal fusion range, and the vertical fusion range to improve the matching degree between the initial eye positions and the user's two eyes, thereby solving the problem of poor split vision effect in the existing binocular fusion training methods and the low matching degree caused by the fixed fusion parameters, as well as the problem of poor final training effect caused by the fixed center position of the initial position of the training screen and the inability to effectively fuse the binocular images when a strabismus user uses it, and the mismatch between the fusion starting point and the eye position.

[0062] In one embodiment, referring Figure 2 as shown, obtaining the initial eye positions corresponding to the user's two eyes respectively includes the following steps S11 to S13.

[0063] S11. Obtain a test image.

[0064] S12. Segment the test image to form a first test image and a second test image with completely different contents, and display them in the display areas corresponding to the user's left and right eyes respectively.

[0065] S13, respectively adjust the positions of the first test image and the second test image in the corresponding display area. When the user's two eyes respectively observe the first test image and the second test image displayed in the corresponding display area and align them to form a test image, the position coordinates of the first test image and the second test image in the corresponding display area are used as the initial eye positions corresponding to the user's two eyes respectively.

[0066] For example, Figure 3 and Figure 4 As shown, Figure 3 The image of a lion in a cage is the test image A. The test image A is segmented into a first test image A1 and a second test image A2 with completely different contents. Figure 4 The first test image A1 shown in the figure only contains a cage, and the second test image A2 only contains a lion. The first test image A1 is placed in the display area B1 corresponding to the left eye, and the second test image A2 is placed in the display area B2 corresponding to the right eye, and the position of the first test image A1 in the display area B1 corresponding to the left eye and the position of the second test image A2 in the display area B2 corresponding to the right eye are adjusted respectively. When the user's eyes respectively observe the first test image A1 displayed in the display area B1 corresponding to the left eye and the second test image A2 displayed in the display area B2 corresponding to the right eye to align to form the test image A, the position coordinates of the first test image A1 in the display area B1 corresponding to the left eye and the position coordinates of the second test image A2 in the display area B2 corresponding to the right eye are respectively used as the initial eye positions corresponding to the user's left eye and right eye, respectively, so that whether it is a normal eye position or an abnormal eye position (for example, a strabismus eye position), the corresponding initial eye position can be determined according to the specific binocular conditions to ensure the matching degree between the initial eye position and the user's binoculars.

[0067] Among them, respectively adjusting the positions of the first test image A1 and the second test image A2 in the corresponding display areas includes: keeping the position of the first test image A1 in the corresponding display area unchanged, and adjusting the position of the second test image A2 in the corresponding display area; or, keeping the position of the second test image A2 in the corresponding display area unchanged, and adjusting the position of the first test image A1 in the corresponding display area; or, adjusting the positions of the first test image A1 and the second test image A2 in the corresponding display area at the same time. Specifically, taking the adjustment of the position of the first test image A1 in the display area B1 corresponding to the left eye as an example, a position is selected as the origin and a rectangular coordinate system is established. The center position of the display area B1 can be selected as the origin. When the first test image A1 is at the origin, the position coordinates of the first test image A1 in the display area B1 are determined to be (0, 0). The first test image A1 can be moved horizontally and / or vertically in the display area B1. Similarly, the same position is selected as the origin in the display area B2 and a rectangular coordinate system is established. That is, the center position of the display area B2 is used as the origin. When the second test image A2 is at the origin, the second test image A2 is moved horizontally and / or vertically in the display area B1. The position coordinates in the display area B2 are determined to be (0, 0), and the second test image A2 can be moved horizontally and / or vertically in the display area B2. Only the first test image A1 can be moved, only the second test image A2 can be moved, or both the first test image A1 and the second test image A2 can be moved at the same time. When the first test image A1 is aligned with the second test image A2, the position coordinates (x1, x2) of the first test image A1 in the rectangular coordinate system established in the display area B1 and the position coordinates (y1, y2) of the second test image A2 in the rectangular coordinate system established in the display area B2 are determined, and they are used as the initial eye positions corresponding to the left eye and the right eye of the user, respectively.

[0068] Step S2: horizontally adjust and vertically adjust the horizontal position and vertical position of the image in the corresponding display area based on the initial eye positions corresponding to the user's eyes, so as to determine the horizontal fusion range and vertical fusion range of the user's eyes.

[0069] Specifically, refer to Figure 5 As shown, before horizontally adjusting and vertically adjusting the horizontal position and vertical position of the image in the corresponding display area based on the initial eye positions corresponding to the user's eyes, the following steps S51 to S52 are also included.

[0070] Step S51, obtaining a test image.

[0071] Step S52: performing deletion processing on the test image to form a third test image and a fourth test image with different parts of content missing, and displaying them in the display areas corresponding to the user's eyes respectively.

[0072] by Figure 3Taking the image of a lion in a cage as an example of test image A, test image A is missing to form a third test image and a fourth test image with different parts missing. For example, the third test image is missing the left front leg of the lion relative to test image A, and the fourth test image is missing the tail of the lion relative to test image A. The third test image and the fourth test image with different parts missing can be merged to form a complete test image A, thereby displaying the third test image and the fourth test image in the display areas corresponding to the user's eyes, respectively.

[0073] It should be noted that the purpose of the deletion processing is to delete part of the image content to form a new image. The aforementioned acquisition of the initial eye positions corresponding to the user's eyes and the determination of the horizontal fusion range and vertical fusion range of the user's eyes are based on Figure 3 The image of a lion in a cage is used as a test image for exemplary explanation. The two test images can be the same image or different images. As long as the initial eye positions corresponding to the user's eyes can be obtained based on the test images and the horizontal fusion range and vertical fusion range of the user's eyes can be determined, this embodiment does not specifically limit this. At the same time, in the present application, preferably, the content in the third test image is approximately 80% similar to the content in the fourth test image.

[0074] Exemplarily, the horizontal position of the image in the corresponding display area is adjusted horizontally based on the initial eye position until the user's two eyes observe the images displayed in the corresponding display area independently, and the horizontal movement distance of the image in the corresponding display area is determined as the horizontal fusion range of the user's two eyes; the vertical position of the image in the corresponding display area is adjusted vertically based on the initial eye position until the user's two eyes observe the images displayed in the corresponding display area independently, and the vertical movement distance of the image in the corresponding display area is determined as the vertical fusion range of the user's two eyes.

[0075] Specifically, refer to Figure 6 As shown, adjusting the horizontal position of the image in the corresponding display area based on the initial eye position level includes the following steps S61 to S63.

[0076] Step S61: The third test image and the fourth test image move in opposite directions at the same speed from the initial eye position level in the corresponding display area until the user's eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the first horizontal movement distances corresponding to the third test image and the fourth test image respectively.

[0077] Step S62: The third test image and the fourth test image move in opposite directions at the same speed from the initial eye position level in the corresponding display area until the user's two eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the second horizontal movement distances corresponding to the third test image and the fourth test image respectively.

[0078] Step S63: defining a horizontal fusion range of the user's eyes by the first horizontal movement distance and the second horizontal movement distance.

[0079] For example, the third test image is placed in the display area B1 corresponding to the left eye, and the fourth test image is placed in the display area B2 corresponding to the right eye. When detecting the horizontal dilation ability range of the user's eyes, the third test image and the fourth test image are moved in opposite directions at the same speed from the initial eye position level in the corresponding display areas (that is, the third test image is moved to the left in the display area B1 from the initial eye position level corresponding to the left eye, and the fourth test image is moved to the right in the display area B2 from the initial eye position level corresponding to the right eye, and the two moving speeds are the same). When the third test image and the fourth test image are seen to be independent, that is, when there is no fusion area between the third test image and the fourth test image under the observation of the user's eyes, the first horizontal movement distances corresponding to the third test image and the fourth test image are recorded. When detecting the horizontal convergence ability range of the user's eyes, the third test image and the fourth test image are moved in opposite directions at the same speed from the initial eye position level in the corresponding display area (that is, the third test image is moved rightward from the initial eye position level corresponding to the left eye in the display area B1, and the fourth test image is moved leftward from the initial eye position level corresponding to the right eye in the display area B2, and the two moving speeds are the same). When the third test image and the fourth test image are seen to be independent, that is, when there is no fusion area between the third test image and the fourth test image under the observation of the user's eyes, the second horizontal movement distances corresponding to the third test image and the fourth test image are recorded. Based on this, the horizontal fusion range of the user's eyes is defined by the first horizontal movement distance and the second horizontal movement distance.

[0080] It should be noted that the aforementioned horizontal divergence ability range is intended to be the ability range of the user's eyes to rotate outward at the same time, and the horizontal convergence ability range is intended to be the ability range of the user's eyes to rotate inward at the same time, and subsequent training of the user's eyes is performed based on this ability range.

[0081] Ginseng Figure 7 As shown, vertically adjusting the vertical position of the image in the corresponding display area based on the initial eye position includes the following steps S71 to S72.

[0082] Step S71: The third test image and the fourth test image move vertically backwards from the initial eye position at the same speed in the corresponding display area until the user's eyes observe the third test image and the fourth test image displayed in the corresponding display area independently, and record the vertical movement distances corresponding to the third test image and the fourth test image respectively.

[0083] Step S72: defining a vertical fusion range of the user's eyes according to a vertical movement distance between the third test image and the fourth test image.

[0084] For example, the third test image is placed in the display area B1 corresponding to the left eye, and the fourth test image is placed in the display area B2 corresponding to the right eye. When detecting the vertical fusion ability range of the user's binoculars, the third test image and the fourth test image are moved in opposite directions at the same speed from the initial eye position in the corresponding display area (that is, the third test image is moved vertically upward from the initial eye position corresponding to the left eye in the display area B1, and the fourth test image is moved vertically downward from the initial eye position corresponding to the right eye in the display area B2, and the two moving speeds are the same, and / or, the third test image is moved vertically downward from the initial eye position corresponding to the left eye in the display area B1, and the fourth test image is moved vertically upward from the initial eye position corresponding to the right eye in the display area B2, and the two moving speeds are the same), when the third test image and the fourth test image are seen to be independent, that is, when the third test image and the fourth test image do not have any fusion area under the observation of the user's binoculars, the vertical movement distances corresponding to the third test image and the fourth test image are recorded. Based on this, the vertical fusion range of the user's binoculars is defined by the vertical movement distance.

[0085] Step S3, within the horizontal fusion range and the vertical fusion range, horizontally and vertically move the images displayed in the display areas corresponding to the user's two eyes respectively from the initial eye position to perform binocular fusion vision function training for the user.

[0086] Exemplarily, firstly, a first training image and a second training image for training are obtained. The first training image and the second training image can be defined by the user. This embodiment does not specifically limit this. In the following description, the first training image is placed in the display area B1 corresponding to the left eye, and the second training image is placed in the display area B2 corresponding to the right eye. However, this does not limit the scope of protection of the present application.

[0087] Specifically, when training the user's ability to spread both eyes horizontally, the first training image and the second training image are cyclically moved horizontally backwards from the corresponding initial eye positions based on the first horizontal movement distance. First, the first training image is placed at the initial eye position corresponding to the left eye in the display area B1 corresponding to the left eye (i.e., the position coordinates (x1, x2)), and the second training image is placed at the initial eye position corresponding to the right eye in the display area B2 corresponding to the right eye (i.e., the position coordinates (y1, y2)). Next, the first training image is moved horizontally to the left from the position coordinates (x1, x2), and the second training image is moved horizontally to the right from the position coordinates (y1, y2). When the first training image is moved to the first horizontal moving distance, the first training image returns to the position coordinates (x1, x2), and the second training image returns to the position coordinates (y1, y2). Then, the first training image is moved horizontally to the left from the position coordinates (x1, x2), and the second training image is moved horizontally to the right from the position coordinates (y1, y2). When the first horizontal moving distance is moved, the first training image returns to the position coordinates (x1, x2) again, and the second training image returns to the position coordinates (y1, y2) again. The cycle is repeated.

[0088] When training the user's binocular horizontal convergence ability, the first training image and the second training image cyclically move horizontally oppositely from the corresponding initial eye positions based on the second horizontal movement distance. First, the first training image is placed at the initial eye position corresponding to the left eye in the display area B1 corresponding to the left eye (i.e., the position coordinates (x1, x2)), and the second training image is placed at the initial eye position corresponding to the right eye in the display area B2 corresponding to the right eye (i.e., the position coordinates (y1, y2)). Next, the first training image is horizontally moved to the right from the position coordinates (x1, x2), and the second training image is horizontally moved to the left from the position coordinates (y1, y2). When the first training image is moved to the first horizontal movement distance, the first training image returns to the position coordinates (x1, x2), and the second training image returns to the position coordinates (y1, y2). Then, the first training image is horizontally moved to the right from the position coordinates (x1, x2), and the second training image is horizontally moved to the left from the position coordinates (y1, y2). When the first horizontal movement distance is moved, the first training image returns to the position coordinates (x1, x2) again, and the second training image returns to the position coordinates (y1, y2) again. The cycle is repeated.

[0089] When training the user's binocular vertical fusion ability, the first training image and the second training image are cyclically moved vertically backward from the corresponding initial eye positions based on the vertical movement distance. First, the first training image is placed at the initial eye position corresponding to the left eye in the display area B1 corresponding to the left eye (i.e., the position coordinates (x1, x2)), and the second training image is placed at the initial eye position corresponding to the right eye in the display area B2 corresponding to the right eye (i.e., the position coordinates (y1, y2)). Next, the first training image is moved vertically upward from the position coordinates (x1, x2), and the second training image is moved vertically downward from the position coordinates (y1, y2). When the vertical movement distance is reached, the first training image returns to the position coordinates (x1, x2), and the second training image returns to the position coordinates (y1, y2). Then, the first training image is moved vertically upward from the position coordinates (x1, x2), and the second training image is moved vertically downward from the position coordinates (y1, y2). When the vertical movement distance is reached, the first training image returns to the position coordinates (x1, x2) again, and the second training image returns to the position coordinates (y1, y2) again. The cycle is repeated. Alternatively, the first training image can be moved vertically downward from the position coordinates (x1, x2), and the second training image can be moved vertically upward from the position coordinates (y1, y2). When moving to the vertical moving distance, the first training image returns to the position coordinates (x1, x2), and the second training image returns to the position coordinates (y1, y2). Then, the first training image is moved vertically downward from the position coordinates (x1, x2), and the second training image is moved vertically upward from the position coordinates (y1, y2). When moving to the vertical moving distance, the first training image returns to the position coordinates (x1, x2) again, and the second training image returns to the position coordinates (y1, y2) again, and the cycle is repeated. Alternatively, the first training image can be moved vertically upward (or downward) from the position coordinate (x1, x2), and the second training image can be moved vertically downward (or upward) from the position coordinate (y1, y2). When moving to the vertical moving distance, the first training image returns to the position coordinate (x1, x2), and the second training image returns to the position coordinate (y1, y2). Then, the first training image is moved vertically downward (or upward) from the position coordinate (x1, x2), and the second training image is moved vertically upward (or downward) from the position coordinate (y1, y2). When moving to the vertical moving distance, the first training image returns to the position coordinate (x1, x2) again, and the second training image returns to the position coordinate (y1, y2) again. The cycle is repeated, and this embodiment does not specifically limit this.

[0090] It should be noted that the movement mode of the first training image and the second training image is stepless smooth movement or jump movement. At the same time, after the user has trained for a period of time based on the aforementioned binocular fusion vision function training method, the initial eye positions corresponding to the user's eyes are re-acquired within a set time and the horizontal fusion range and vertical fusion range of the user's eyes are determined for updating, thereby ensuring the matching degree of the current initial eye position, horizontal fusion range and vertical fusion range with the current state of the user's eyes. In addition, the movement distance of the aforementioned first training image and the second training image can be increased by a small amount, such as a correction amount less than or equal to 5 prism degrees.

[0093] It should be noted that the logic contained in step S1 in the aforementioned binocular fusion vision function training method is implemented by the acquisition module 101 in the binocular fusion vision function training device, the logic contained in step S2 in the aforementioned binocular fusion vision function training method is implemented by the determination module 102 in the binocular fusion vision function training device, and the logic contained in step S3 in the aforementioned binocular fusion vision function training method is implemented by the training module 103 in the binocular fusion vision function training device.
