Description

Technical Field

[0002] Naked-eye 3D visual training belongs to eye movement training and is an effective non-contact myopia prevention and control measure and program. Naked-eye 3D uses the characteristics of parallax fusion of the two eyes of the human body to directly obtain realistic three-dimensional images with space and depth with the human eye without the need for any auxiliary equipment (such as glasses, helmets, etc.). The naked-eye 3D visual training of Stereotong Company is a new type of myopia prevention and control method based on naked-eye 3D technology. It combines dynamic stereoscopic content with naked-eye 3D display technology based on AI pupil tracking technology and ophthalmology, and belongs to the category of eye movement and visual training. Compared with traditional training equipment, naked-eye 3D visual training can carry out all-round visual training at the same time, effectively overcome the impact of flat fixation on the eyes, and make vision healthier. The naked-eye 3D of stereoscopic vision plays specific 3D animations and dedicated playback and display devices, and users watch videos to relax their eye muscles and improve their vision.

[0003] At present, there are many research papers on naked-eye 3D vision training in China that have proven its effectiveness. For example, the "Research on the Influence of Naked-Eye Stereoscopic (3D) Visual Training on the Accommodative Function of the Human Eye" by the Zhongshan Eye Center of Sun Yat-sen University shows that naked-eye stereoscopic (3D) vision training has the function of accommodation training and can enhance the accommodation flexibility of the human eye; the "Immediate Effect of Naked-Eye 3D Vision Training on the Accommodative Function of Myopic Patients" by the Affiliated Eye, Ear, Nose and Throat Hospital of Fudan University shows that naked-eye 3D vision training can significantly improve the accommodation function of both eyes, and the accommodation sensitivity is enhanced and the accommodation lag is reduced after training.

[0004] Some of these naked-eye 3D vision training methods require the combination of AI pupil tracking technology and naked-eye 3D display technology, which is limited to one device and one trainee, and is not suitable for occasions where multiple people are trained at the same time; some require specific 3D videos and professional display equipment, which is also limited to one device and one trainee.

[0079] The single-image naked-eye 3D vision training method provided in this embodiment; this method includes: a training parameter configuration module, a rendering control module, a rendering module and a training control module, especially including an execution process to display the content of the repeating unit repeatedly along the horizontal axis on the display terminal to obtain a repeating composition with single-image naked-eye 3D characteristics; if the training selected by the parameter configuration module is reading training, the repeating composition unit is text and pictures, and the trainee completes the reading training in the naked-eye 3D state. If the training selected by the training parameter configuration module is vision training, the trainee completes the vision training in the naked-eye 3D state.

[0080] As Figure 1 shown, the single-image naked-eye 3D vision training method provided in this embodiment; this method includes: a training parameter configuration module, a rendering control module, a rendering module and a training control module, especially including an execution process to display the content of the repeating unit repeatedly along the horizontal axis on the display terminal to obtain a repeating composition with single-image naked-eye 3D characteristics; form a 3D animation with dynamic regular changes in depth of field; if the trainee enters the naked-eye 3D state, then conduct naked-eye 3D vision training; if the trainee does not enter the naked-eye 3D state, then conduct vision training with depth-of-field change in the fixation state.

[0081] As Figure 2As shown in the figure, the specific execution process specifically includes:

[0082] Step 1: Obtain the coordinates of the display area and the central vertical axis coordinate of the display area; open a display cache.

[0083] Step 2: Calculate the background color, the color of the repeating unit, and the orientation of the repeating unit.

[0084] Step 3: Calculate the size of the repeating unit, the vertical interval between the upper and lower repeating units, the horizontal interval between adjacent repeating units, and the number of columns M and rows N of the repeating units to be drawn.

[0085] Step 4: If M is odd, render N repeating units in a column to the central vertical axis position of the display cache, and then render the remaining M - 1 columns of repeating units to the display cache in both horizontal directions according to the repeated composition method based on the horizontal interval parameter; if M is even, render two columns of repeating units to both sides of the central vertical axis along the central vertical axis, and then render the remaining M - 2 columns of repeating units to the display cache according to the repeated composition method based on the horizontal interval parameter.

[0086] Step 5: Update the display cache to the display terminal.

[0087] As Figure 3 shown, the vision training method includes a training parameter configuration module, and the module includes: Module 1, training item setting module: training item selection, repeating unit selection, repeating unit management; Module 2, color change configuration module: optional black and white mode, gray gradient mode, color cycle mode; Module 3, orientation change configuration module: optional full column one-way, full column up and down, full column left and right, full column four-way cycle, full column four-way random, repeating unit four-way random; Module 4, scaling configuration module: the position mode can be fixed position and synchronous position scaling; the scaling mode can be static mode, scaling cycle, scaling cycle, shrinking cycle, enlarging cycle, scaling combination; Module 5, scaling speed configuration module: configure the scaling change step size and time interval; Module 6, training duration configuration module: configure the training duration; Module 7, alarm reminder configuration module: configure the timing alarm, countdown alarm, alarm type and alarm duration; Module 8, training management module: manage user information and training records.

[0088] As Figure 4 shown, the vision training method especially includes a rendering control module to complete the content of steps 1 to 4 in claim 1. The rendering control center, according to the configuration parameters of Module 1, Module 2, Module 3, Module 4, and Module 5, completes (1) obtaining the coordinates of the display area and the central vertical axis coordinate of the display area; opening a display cache; (2) calculating the background color, color, and orientation; (3) calculating the size of the repeating unit, the vertical interval, the horizontal interval, and the number of columns M and rows N of the repeating units to be drawn.

[0089] As shown in Figure 5 the figure, a vision training method, especially including a rendering module, the rendering module reads the parameters calculated by the rendering control module, and includes a display cache; reads the parameters calculated by the rendering control module. If M is odd, render the content of N repeating units in a column to the central vertical axis position of the display cache, and then render the content of the remaining M-1 columns of repeating units to the display cache along both horizontal directions according to the repeated composition method based on the horizontal interval parameter; if M is even, render the content of two columns of units to both sides of the central vertical axis respectively, and then render the content of the remaining M-2 columns of repeating units to the display cache according to the repeated composition method based on the horizontal interval parameter.

[0090] A vision training method, especially including a training control center, the training control center reads the training duration configured by the training duration configuration module to control the training duration; reads the parameters configured by the alarm reminder configuration module to control the execution of the alarm; records the training file.

[0091] When the training selected by the training configuration module is vision training, the content of the repeating unit can be selected from the classics of vision tests, or can be any letter or Chinese character. When the training item is reading, the content of the repeating unit is replaced with the content in reading to construct the repeating unit.

[0092] As shown in Figure 2 the figure, when the content of the repeating unit is text, the training process also needs to be slightly modified, as follows:

[0093] Step 1: Obtain the coordinates of the display area and the central vertical axis coordinate of the display area; open a display cache;

[0094] Step 2: Calculate the background color and the text color;

[0095] Step 3: Calculate the font size, line spacing, and the number of columns M and rows N of the repeating units to be drawn;

[0096] Step 4: If M is odd, render N repeating units in a column to the central vertical axis position of the display cache, and then render the remaining M-1 columns of repeating units to the display cache along both horizontal directions according to the repeated composition method based on the horizontal interval parameter; if M is even, render two columns of repeating units along the central vertical axis to both sides of the central vertical axis respectively, and then render the remaining M-2 columns of repeating units to the display cache according to the repeated composition method based on the horizontal interval parameter;

[0097] Step 5: Update the display cache to the display terminal.

[0098] Correspondingly, when the training item selected by the training configuration module is reading training, as shown in Figure 4The rendering control module shown also needs to be slightly modified, specifically including: Module 1 remains unchanged; Module 2 remains unchanged; Module 3 is cancelled; Module 4 remains unchanged; Module 5 remains unchanged; Module 6 remains unchanged; Module 7 remains unchanged; Module 8 remains unchanged.

[0099] Correspondingly, when the training item selected by the training configuration module is reading training, as Figure 3 shown, the training parameter configuration module also needs to be slightly modified, specifically including: The rendering control center, according to the configuration parameters of Module 1, Module 2, Module 3, Module 4 and Module 5, completes (1) obtaining the display area coordinates and the central longitudinal axis coordinate of the display area; opening a display cache; (2) calculating the background color and font color; (3) calculating the font size, line spacing, vertical interval, horizontal interval and the number of columns M and rows N of the repeating units to be drawn.

[0100] As Figure 5 shown, correspondingly, when the training item selected by the training configuration module is reading training, the rendering module is slightly modified, specifically as follows: The rendering module reads the parameters calculated by the rendering control module and includes a display cache; reads the parameters calculated by the rendering control module. If M is odd, render N repeating units in a column to the central longitudinal axis position of the display cache, and then render the content of the remaining M - 1 columns of repeating units to the display cache along the two horizontal directions according to the repeated composition method and based on the horizontal interval parameter; if M is even, render the content of two columns of repeating units to both sides of the central longitudinal axis respectively, and then render the content of the remaining M - 2 columns of repeating units to the display cache according to the repeated composition method and based on the horizontal interval parameter.

[0101] As Figure 6 shown, the schematic diagram of the central longitudinal axis of the visible area when M is odd, the horizontal axis is perpendicular to the longitudinal axis.

[0102] As Figure 7 shown, when M = 9 and N = 9, the repeated composition obtained by rendering. One column of E is on the longitudinal axis, and the remaining columns are evenly distributed on both sides of the central longitudinal axis. Under naked-eye 3D observation, the human eye can see a 3D map of M + 1 columns of E columns.

[0103] As Figure 8 shown, when M is even, render N Es on both sides of the central longitudinal axis respectively to form two columns of E.

[0104] As Figure 9 shown, when M = 8 and N = 9, the schematic diagram of the repeated composition obtained by rendering; the schematic diagram of the repeated composition of M columns of E along the horizontal axis. M / 2 columns are distributed on both sides of the central longitudinal axis respectively. Under naked-eye 3D observation, the human eye can see a 3D map of M + 1 columns of E columns.

Figure 19 Represents the case where M=4 and N=1, with a diagram of repeated composition using part of the Tao Te Ching as an example.

In the figure, the scaling rules of the gray E and the white E are opposite. When the gray E is enlarged, the white E is reduced; when the white E is enlarged, the gray E is reduced.

The display surface of the display terminal can form a closed space to form an immersive training experience.

[0135] As Figures 25 - 26 shown, in specific implementation, the device further includes one or more processors and one or more memories; one or more memories are coupled to one or more processors, and one or more memories are used to store computer program codes. The computer program codes include computer instructions. When one or more processors execute the computer instructions, the terminal executes the above device. Among them, the image constructed by the repeated composition can be rendered to the display terminal, and the shape can be a flat surface, a curved surface, a cylindrical surface or any combination of the three.

[0136] This embodiment is based on a user terminal, a display terminal, and a server; the display terminal includes an execution process to repeatedly compose and display E along the horizontal axis on the display terminal, obtaining a repeatedly composed image with the characteristics of single-image naked-eye 3D; the display terminal includes a display selected from a flat surface, a curved surface, a cylindrical surface, or any combination of the three. The user terminal is used to execute a training parameter configuration module, send the training parameters to the server, and complete the training items presented on the display terminal according to the configured training parameters; the server accepts the training parameter configuration and sends the specific detailed training parameters to the user terminal and the display terminal; the display terminal completes rendering the repeatedly composed image with the characteristics of single-image naked-eye 3D according to the training parameters transmitted by the server.

[0137] Single-image naked-eye 3D vision training process: First step, set the training state to a static single image. Second step, activate the binocular naked-eye 3D state in the fixation state. Third step: In the naked-eye 3D state, use a dynamic image to activate the regular movement of the eye muscle group. Fourth step: Close the eyes to relax the eye muscle group.

[0138] Method for activating the naked-eye 3D state in the fixation state: Let the eyes fixate on a static repeatedly composed single image at a distance of 20 to 30 centimeters, then relax the eyes to make the pupils diverge, and slowly move backward. Try several times and a 3D picture will appear. When entering the naked-eye 3D state, the picture brightness suddenly increases, the resolution increases, and the picture feels much clearer instantly, but it will become smaller and farther away (a sense of distance is generated), and the number of columns of the repeatedly composed image seen in the naked-eye 3D state will be one column more than that in the fixation state.

[0139] After both eyes enter the naked-eye 3D state for a 2-column repeatedly composed image, three columns will be seen. The middle column has a stable three-dimensional effect, and the left and right two images seem to exist within the "peripheral vision" range and are a bit blurry. During vision training and reading, focus on observing the middle column without deliberately observing the two side columns.

[0140] After both eyes enter the naked-eye 3D state for a 3-column repeatedly composed image, four columns will be seen. The middle two columns have a stable three-dimensional effect, and the left and right two columns seem to exist within the "peripheral vision" range and are a bit blurry. During vision training and reading, focus on observing the middle column without deliberately observing the two side columns.

[0141] After both eyes enter the naked-eye 3D state for an M-column repeatedly composed image, M + 1 columns will be seen. The middle M - 2 columns have a stable three-dimensional effect, and the left and right two columns seem to exist within the "peripheral vision" range and are a bit blurry. During vision training and reading, focus on observing the middle column without deliberately observing the two side columns. For beginners, observing the two side columns will cause the binocular naked-eye 3D state to disappear. After training, looking at the left and right two columns will not cause the naked-eye 3D state to disappear. Compared with 2-column and 3-column images, for an M-column repeatedly composed image where M is greater than 3 columns, the naked-eye 3D state is more stable.

[0142] After both eyes enter the naked-eye 3D state, the eye muscle groups can be trained in two ways: The first is to observe a single view by moving forward, backward, left, right, up, and down to achieve the training of the eye muscle groups. The second is to keep the eye distance unchanged and adjust the repeated composition content according to the depth-of-field change rule set by the system to achieve the training of the eye muscle groups.

[0143] A single-image naked-eye 3D vision training method of the present invention does not require special equipment and can be implemented on a common display terminal, which is convenient for popularization; one device can be used by multiple people at the same time, especially suitable for multi-person application scenarios, such as schools, hospitals, medical institutions, and vision bars, etc., for popular use in multiple scenarios.

[0144] As an embodiment, when deployed in schools, a single-image naked-eye 3D training system can be deployed on the monitors in the classrooms. Only need to run the training system during the break, and the students can enter the naked-eye 3D vision state during their free time, and naturally complete the massage and relaxation of the eye muscles. By this method of multi-person deployment on ordinary display devices, the implementation difficulty is greatly simplified, the implementation cost is reduced, and the audience is wider. Deployed at home in the same way, a family can train at the same time.

[0145] As an embodiment, when deployed in a vision bar, the vision bar can be deployed into a hexahedron display space with six-sided displays, or can be deployed into a cylindrical display space, and is uniformly synchronized and controlled by one server. Multiple trainees in one space can train at the same time, and the trainees can have a better training experience.

[0146] The present invention has been described in detail above in conjunction with the embodiments with reference to the drawings. Those of ordinary skill in the art can make various variations of the present invention according to the above description. Therefore, some details in the embodiments should not constitute a limitation to the present invention, and the present invention will take the scope defined by the appended claims as the protection scope.
