[0093] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0094] The specific embodiment of the method for generating a visual stereogram for visual function training provided by the present invention is described in detail below:

[0095] Example 1

[0096] 1. Basic conditions setting

[0097] 1.1 Set the training distance, i.e. the reading distance ReadingD. In Example 1, ReadingD=400mm;

[0098] 1.2 Set the number of lines of a text, TextL. In Example 1, set TextL=8;

[0099] For the sake of convenience, assume that the content of the first line of text is the "first line of text",..., and the content of the eighth line of text is the "eighth line of text".

[0100] 1.3 Set the total width of each line of text LineN. In Example 1, LineN=100 mm.

[0101] 1.4 When reading 3D books, readers need to wear red-green glasses, with the left lens being green and the right lens being red.

[0102] 1.5. Set 3 color values.

[0103] 1.5.1 Background color BColour. The possible values ​​are RGB (255, 255, 128);

[0104] 1.5.2 Left eye lens filter color LColour. How to determine LColour: If you use the color LColour to draw a pattern on the background color, when the reader wears red-green glasses to view the image, the left eye cannot see the pattern on the image, but the right eye can see the pattern clearly. LColour can take the value of RGB(128,255,128).

[0105] 1.5.3 Right eye lens filter color RColour. RColour is determined by: If a pattern is drawn on the background color with the color RColour, when the reader wears red-green glasses to view the image, the right eye cannot see the pattern on the image, while the left eye can see the pattern clearly. RColour can take the value of RGB(255,144,128).

[0106] 2. Design Method

[0107] 2.1. Design a guiding slope for collective training.

[0108] The design method is as follows:

[0109] 2.1.1、Design the first table, such as Figure 1 As shown, the background color is BColour, and a table is drawn on the picture with LColour color. The table has 8 horizontal grid lines (corresponding to TextL=8) distributed at equal distances; the left and right endpoints of the i-th horizontal grid are Ai and Bi (i=1, 2, ..., 8);

[0110] The table has a number of vertical line segments distributed at equal distances, and the number of vertical line segments may range from 5 to 20. In Example 1, 9 vertical line segments are taken as an example.

[0111] 2.1.2. Figure 1 The 8th horizontal line B8 is compressed to the left, Figure 1 Transform into a right-angled trapezoid with point A1 in the upper left corner as a right angle, such as Figure 3 shown.

[0112] After deformation, the length from Ai to Bi is shortened by m compared to before compression. i (mm);

[0113] m8, m7, ..., m1 are an arithmetic sequence, and m1=0.

[0114] In Example 1, m8 is 120 mm.

[0115] 2.1.3, Design the second table, such as Figure 2 As shown. The background color is BColour. The foreground pattern is Figure 1 Same, use RColour for the foreground color.

[0116] 2.1.4. Figure 2 The 8th horizontal line C8 is compressed to the right, Figure 2 Transform into a right-angled trapezoid with point D1 in the upper right corner as a right angle. Figure 4 shown.

[0117] After deformation, the length from Ci to Di is shorter than before compression by the same value m in 2.1.2. i . m8=120mm, m8, m7, …, m1 is an arithmetic sequence, and m1=0.

[0118] 2.1.5. Generate a set of training guide slopes.

[0119] Will Figure 3 and Figure 4 The top horizontal line segment of the two images completely overlaps, and all the points of the two images are superimposed in the way of "taking the minimum value of the corresponding point color", forming Figure 5 .

[0120] The so-called "corresponding point color takes the minimum value" means: for any point (x, y) on the image, assuming that Figure 3 The color value of the upper (x, y) point is RGB (r1, g1, b1); Figure 4 The color value of the point (x, y) is RGB (r2, g2, b21); then Figure 5 The calculation formula for the color value RGB (r3, g3, b3) of the point (x, y) is:

[0121] If (r1<r2), then r3 takes the value of r1, otherwise r3 takes the value of r2;

[0122] If (g1<g2), then g3 takes the value of g1, otherwise g3 takes the value of g2;

[0123] If (b1<b2), then b3 takes the value of b1, otherwise b3 takes the value of b2;

[0124] When wearing red-green glasses Figure 5 If you close your right eye and open your left eye, all you see is Figure 4 If you close your left eye and open your right eye, you will see only Figure 3 If both eyes are open to look at the image at the same time, according to the "binocular convergence phenomenon mechanism", a table-shaped slope from top to bottom and from far to near will be seen. In this design, this slope is called the collective training guiding slope.

[0125] Original Figure 3 Yohara Figure 4 The first horizontal line in Figure 5 The coincidence is the straight line L1;

[0126] Original Figure 3 Yohara Figure 4 The i-th horizontal line (i≥1) in Figure 5 In the same straight line; Figure 5 Central, original Figure 3 Ai point and original Figure 4 The distance between the Ci points is m in 2.1.2 i .

[0127] 2.2 Design a set of training stereograms, such as Figure 6 shown.

[0128] The design method is as follows:

[0129] 2.2.1、 Figure 5 Add text to form Figure 6 .

[0130] Assume that the text to be added is the i-th line (i=1, 2, ..., 8), and the i-th line of text is typeset into two lines of text LWi and RWi in the specified font size and two colors, LColour and RColour, respectively; align the lower edge of LWi with Li in the "minimum value of corresponding point color" method, and place the center point of LWi at a distance of Figure 5 Vertical center line left m i / 2 position, add to Figure 5 On; align the lower edge of RWi with Li, with the center point of RWi at a distance Figure 5 Vertical center line right m i / 2 position, add to Figure 5 superior.

[0131] When wearing red-green glasses Figure 5 When you look at the table, you will see that above each horizontal line on the inclined surface from far to near, there is a line of text standing upright, thus forming 8 lines of text from far to near.

[0132] Example 2

[0133] Embodiment 2 is based on embodiment 1 and further includes the following design steps:

[0134] 2.2.2, in Figure 6 On the top, mark the set degree corresponding to each line of text to form Figure 7 .

[0135] Under the premise that the viewing distance is 400mm, in optometry, when doing convergence training, the horizontal displacement of the corresponding points of the red and green sight mark patterns by 4mm is recorded as 1ΔBO.

[0136] To indicate the degree of the i-th row, first replace m in 2.1.2 i The value is expressed in BO and is typeset in two colors, LColour and RColour, and then added to the corresponding point color in the way of "taking the minimum value". Figure 6 , align the bottom edge of the text with color LColour with Li, and the left edge with Figure 6 Align the left line; align the bottom edge of the text with color RColour with Li, and the left edge with Figure 6 The distance to the left line is m i .

[0137] When wearing red-green glasses Figure 7 When you look at the table, you will see that above each horizontal line on the inclined plane from far to near, there is a line of text standing upright, thus forming 8 lines of text from far to near, and the left side of each line of text is marked with the convergence degree of the line of text when the viewing distance is 40cm.

[0138] Example 3

[0139] Designed to spread out training guide slopes, such as Fig.10 shown.

[0140] The design method is as follows:

[0141] 2.3.1. Figure 1 The 8th horizontal line A8 is compressed to the right, Figure 1 It transforms into a right-angled trapezoid with point B1 in the upper right corner as a right angle. Figure 8 shown.

[0142] After deformation, the length from A8 to B8 is shortened by n8 compared to before compression, and the value of n8 is 64 mm. n8, n7, ..., n1 are an arithmetic sequence, and n1 = 0.

[0143] 2.3.2. Figure 2 The 8th horizontal line D8 is compressed to the left, Figure 2 Transform into a right trapezoid with the upper left corner C1 as a right angle. Fig. 9 shown.

[0144] After deformation, the length from C8 to D8 is shortened by the same value as before compression, which is n8 in 2.3.1, n8=64 mm, n8, n7, ..., n1 is an arithmetic sequence, and n1=0.

[0145] 2.3.3. Generate a scattered training guide slope. Figure 8and Fig. 9 The top horizontal line of the two images completely overlaps, and all the points of the two images are superimposed in the way of "taking the minimum value of the corresponding point color", forming Fig.10 .

[0146] When wearing red-green glasses Fig.10 When both eyes are open to look at the image, according to the "binocular convergence phenomenon mechanism", a tabular slope from top to bottom and from near to far will be seen. This slope is called the "divergence training guiding slope".

[0147] Original Figure 8 and Fig. 9 The first horizontal line in Fig.10 The coincidence is the straight line L1;

[0148] Original Figure 8 and Fig. 9 The i-th horizontal line (i≥1) in Fig.10 In the same straight line. Fig.10 Central, original Figure 8 Ai point and original Fig. 9 The distance between the Ci points is n in 2.3.1 i ;

[0149] 2.4. Design a scattered training stereogram, such as Fig.11 shown.

[0150] The design method is as follows:

[0151] 2.4.1. Fig.10 Add text to form Fig.11 .

[0152] Assume that the text to be added is the i-th line (i=1, 2, ..., 8), and the i-th line of text is typeset into two lines of text LWi and RWi in the specified font size and two colors, LColour and RColour, respectively; align the upper edge of LWi with Li in the "minimum value of corresponding point color" method, and place the center point of LWi at a distance of Fig.10 Vertical center line right n i / 2 position, add to Fig.10 On; align the upper edge of RWi with Li, and the center point of RWi is at a distance Fig.10 Vertical center line deviates to the left i / 2 position, add to Fig.10 superior.

[0153] When wearing red-green glasses Fig.12 When you look at the text, you will see that under each horizontal line on the inclined surface of the table from near to far, there is a line of text hanging vertically, thus forming 8 lines of text from near to far.

[0154] Example 4

[0155] Embodiment 4 is based on embodiment 3 and further includes the following design steps:

[0156] 2.4.2, in Fig.11 Finally, the three-dimensional diagram for dispersion training in Example 4 is formed, that is, Fig.12 .

[0157] Under the premise that the viewing distance is 400mm, in optometry, during dispersion training, the horizontal displacement of the corresponding points of the red and green sight mark patterns by 4mm is recorded as 1ΔBI.

[0158] To mark the spread of the i-th row, first replace n in 2.3.1 i The value is expressed as BI, and is typeset into text in two colors, LColour and RColour, and then added to the corresponding point color in the way of "taking the minimum value". Fig.11 , align the top edge of the text with color RColour with Li, and the left edge with Fig.11 Align the left line; align the top edge of the text with color LColour with Li, and the left edge with Fig.11 The distance to the left line is n i .

[0159] When wearing red-green glasses Fig.12 When you look at the picture, you will see that under each horizontal line on the inclined surface of the table from near to far, there is a line of text hanging vertically, thus forming 8 lines of text from near to far. And the left side of each line of text is marked with the dispersion of the line of text when the viewing distance is 40cm.

[0160] Example 5

[0161] For some readers who are new to 3D books, since they have never seen a 3D book or 3D painting before, they may not be able to understand it at first. Figure 6 , Figure 7 In order to master the reading skills as quickly as possible, readers can first use the [Picture Viewing Wizard] (patent number: ZL 2023 23378584.X) to view the page in three-dimensional form. After reading it several times and mastering the reading skills, there is no need to use the [Picture Viewing Wizard] anymore.

[0162] exist Figure 5 At the upper 1 / 3 of the , two dashed lines are added to obtain the example 5. Fig.13 The set training stereogram shown is used to assist in viewing the image through these two dotted lines.

[0163] ⑴ Hold the [Picture Guide] flat, with the end without the vertical edge against the middle of the bridge of your nose, and the other end not against any object. Then relax your mind, look forward along the [Picture Guide], and slowly you will see the two identical patterns (fish) at the front of the [Picture Guide] as one pattern.

[0164] ⑵ After seeing it as a pattern, slowly place the front end of the [Picture Viewing Guide] against the middle of the page of the 3D book, with the top edge of the guide aligned with the Fig.13 Align the two dotted lines in the picture, and then slowly move your eyes to the page of the 3D book, and a 3D scene will appear in front of you. Then take away the [Picture Guide] and you can enjoy the 3D scene of the whole painting.

[0165] ⑶For scattered training Fig.11 and Fig.12 You can also use the [Image Viewer] (patent number: ZL2019 20882960.3) to see the three-dimensional effect.

[0166] Generally speaking, after reading a few times with the help of the [Picture Wizard], you will gradually master the skills of reading 3D books. When you read 3D books again, you will be able to quickly see the 3D effect without the [Picture Wizard].

[0167] In other optional embodiments of the present invention, the text in the above embodiments may be replaced by patterns.

[0168] Example 6

[0169] The difference between Example 6 and Example 1 is that the text is replaced with silhouettes of some sports events.

[0170] In order to increase the diversity of book 3D display, Figure 1 On the premise that the positions of points B1 and B8 remain unchanged, the straight line from B1 to B8 can be replaced by a curve, such as a quadratic spline curve, an exponential curve, a tangent curve, or even a more complex curve.

[0171] Example 7

[0172] like Fig.15 As shown, Figure 1 The straight lines in are replaced by curves converted by the quadratic spline function to obtain the first guide line group. Figure 2 When the straight line in is replaced by a curve, the same curve function is also needed to be used to convert and obtain the second guide line group. Then the guide line group is generated in the same way as in Example 1, such as Fig.16 Wear red-green glasses to see Fig.16 When you are guiding the slope in the collective training, you will see that the slope is steep at first and then gentle.

[0173] and Fig.16Corresponding to the set training guide slope, when generating the scattered training guide slope, it is necessary to adjust the distance between the LColour color text and the RColour color text to ensure that the three-dimensional text stands above the corresponding horizontal line. Similarly, the scattered training guide slope can be obtained.

[0174] The following is a description of the basic conditions and related parameters in the optional embodiments of the present invention:

[0175] 3.1. In optometry, the training target of collective training is 30ΔBO; the training target of discrete training can reach 15ΔBI, and generally the maximum value does not exceed 20ΔBI. In this design, the training target value of discrete training is set to 16ΔBI.

[0176] 3.2, Reading D = 400mm. This is the training distance set by most optometry training equipment. Although this distance can also be changed, if it changes, the BO and BI values ​​must be changed accordingly, for example:

[0177] If the viewing distance is 20cm, the horizontal distance corresponding to 1ΔBO is 2mm. In 2.1.2, the value of m8 should be set to m8=60mm;

[0178] If the viewing distance is 60cm, the horizontal distance corresponding to 1ΔBO is 6mm. In 2.1.2, the value of m8 should be set to m8=180mm;

[0179] If the viewing distance changes, the size of the final visual stereogram used for visual function training should also be adjusted accordingly.

[0180] 3.3、The number of lines in a text is TextL. TextL can be no less than 2, and should be determined based on the content of the text and the layout effect.

[0181] 3.4. The total width of each line of text LineN can be any value. However, since it is one of the important indicators for determining the total width of the visual stereogram used for visual function training, the formula for the total width is:

[0182] Total width = LineN + 120mm

[0183] Therefore, the value of LineN should be determined by comprehensively considering factors such as image display and printing. In Examples 1 to 5, LineN=100mm. The width of the final designed image is 220mm. This size is not only suitable for screen viewing, but also suitable for printing into 8k book pages.

[0184] 3.5.BColour=RGB(255,255,128);LColour=RGB(128,255,128);RColour=RGB(255,144,128) is a set of optimal color values ​​given in this design. In fact, this set of values ​​can also be adjusted, but it is necessary to comply with the principles of 1.5.2 and 1.5.3.

[0185] 3.5.1. If the user is required to wear red-green glasses, but the left lens is red and the right lens is green, the LColour and RColour color values ​​mentioned above should be interchanged when designing the above images.

[0186] 3.5.2. If the user is required to wear red-blue glasses, with the left lens being blue and the right lens being red, the following set of color values ​​can be used when designing the above image:

[0187] BColour=RGB(255,128,255); LColour=RGB(160,160,255); RColour=RGB(255,144,128)

[0188] 3.5.3. If the user is required to wear red-blue glasses, but the left lens is red and the right lens is blue, the LColour and RColour color values ​​in 3.5.2 should be swapped when designing the above images.

[0189] 3.5.4 If users are required to wear red-cyan glasses, they should select appropriate BColour, LColour and RColour while complying with the principles of 1.5.2 and 1.5.3.

[0190] 3.6. The contents displayed in 3D books are not limited to text. They can also display animals, plants, flowers and birds, and any artistic patterns. Fig.14 In the figure, each row shows the silhouettes of some sports events.

[0191] 3.7. When designing a stereogram for collective training, when the first table is transformed into the first guide line group, point A1 can also be compressed to the right. Correspondingly, when the second table is transformed into the second guide line group, point D1 can also be compressed to the left. After such a transformation, m1≠0, therefore, m8 must also be changed accordingly to satisfy the relationship: m1+m8=120mm, ensuring that when the training distance is 40cm, the training target of collective training is 30ΔBO.

[0192] Similarly, when designing a three-dimensional diagram for dispersed training, if the first table is transformed into the first guide line group, point B1 can also be compressed to the left, and if the second table is transformed into the second guide line group, point C1 can also be compressed to the right. After such transformation, n1≠0, then n8 must also be changed accordingly to satisfy the relationship: n1+n8=64mm, ensuring that when the training distance is 40cm, the training target of the dispersed training is 16ΔBI.

[0193] 3.8. Figures 1 to 14 In the patterns shown, the vertical line segments are not necessarily limited to straight lines, but can be curves, such as sine curves (such as Fig.17 ), sine curve superimposed on cosine curve (such as Fig.17 It can also be a combination of multiple patterns (such as Fig.17 As shown in the right figure, the collective training guide slope can be generated by following the transformation and superposition method given in 2.1; the scattered training guide slope can be generated by following the transformation and superposition method given in 2.3.

[0194] The present invention provides a visual stereogram for visual function training and a generation method thereof. By utilizing the generation method of the visual stereogram for visual function training provided by the present invention, the visual stereogram for visual function training provided by the present invention can be obtained.

[0195] By using the method for generating a visual stereogram for visual function training provided by the present invention, ordinary documents can be made into visual stereograms for visual function training, and multiple visual stereograms for visual function training can be printed and bound into a book to make a visual stereo book. Readers can achieve visual function training in the process of reading the visual stereo book, including training to expand the range of fusion, training to improve fusion ability, stereoscopic vision training, etc.

[0196] The present invention designs a visual three-dimensional book based on the "binocular convergence phenomenon mechanism". When a reader wears red and green glasses to read the visual three-dimensional book provided by the present invention, he sees that each line of text in the book is closer to the eyes than the previous line of text; or each line of text is farther away from the eyes than the previous line of text, and the whole page of the book is a three-dimensional scene that is gradually closer or farther away. The process of the reader reading the book is the process of training the eyes to focus or disperse.

[0197] The existing instruments and equipment for visual function training cannot effectively combine training and learning. Since the training time conflicts with the learning time, and training often affects learning, people are unable to persist in spending more time on training.

[0198] If some content is selected from Chinese, foreign language and other courses in each grade and compiled into a visual three-dimensional book, each student will look at the content that has just been learned, is being learned, or is about to learn when doing visual function training. This will effectively combine visual function training with learning. Readers can persist in spending more time on training, greatly enhancing the effect of visual function training.

[0199] In addition to being printed into paper books, visual stereograms used for visual function training can also be displayed on electronic devices such as desktops, PADs, or mobile phones through application software such as APP, which greatly facilitates readers' training.

[0200] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

[0201] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one", "one" or "the" do not indicate quantity restrictions, but indicate that there is at least one. Similar words such as "include" or "comprise" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Similar words such as "connect" or "connected" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
