Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, fig. 1 is a flowchart of a method for calibrating optotype color according to an embodiment of the present invention, including steps 101 to 104, specifically as follows:
step 101: initializing a calibration interface according to a preset first RGB channel value, and setting a left visual target and a right visual target in the calibration interface, wherein the left visual target and the right visual target are respectively set to be a red visual target and a Lan Seshi visual target;
in this embodiment, taking a case that a user wears red-blue glasses (a left-eye blue lens and a right-eye red lens) to perform binocular vision function training, a specific color image is watched under a specific color lens, and the color of the image after passing through the lens is consistent with that of the image background after passing through the lens, thereby realizing a filtering effect. As shown in fig. 2, for example, a red lens will filter an image of red (# FF 0000) in the screen against a magenta (# FF00 FF) background, and a blue lens will filter an image of blue (# 0000ff) in the screen. That is, on a magenta background, the left eye can only see the red optotype and the right eye can only see the blue optotype. As shown in fig. 3, the specific filtering principle is that the magenta (#ff00 FF) background is red (#ff0000) and blue (#0000 FF) respectively under red-blue lens filtering. The red (#FF 0000) image is red (#FF 0000) and purple (principle of three primary colors, red and blue change into purple) respectively under the filtration of the red and blue lens, so that the red background and the red image realize hiding effect in the red lens, and the blue background and the purple image realize display effect; similarly, the blue (# 0000 FF) image is respectively purple (three primary colors: red plus blue to violet) and blue (# 0000 FF) under the filtering of the red and blue lenses, so that the red background and the purple image in the blue lenses realize the display effect and the blue background and the blue image realize the hiding effect.
In this embodiment, when performing the calibration of the optotype color, a background of magenta (#ff00 FF) is set on the calibration interface through a preset first RGB channel value, and a left optotype and a right optotype are set on the magenta background, where the left optotype is set as a red optotype and the right optotype is set as a blue optotype.
The left and right optotypes may be provided in the present embodiment as simple patterns, geometric figures, numbers or letters, etc.
In this embodiment, the left-side optotype and the right-side optotype are default set to be optotypes with the same size and shape and different colors.
In this embodiment, taking the example that the left-side optotype and the right-side optotype are set to solid circles with the same size and different colors, the left-side optotype is set to a red solid circle, and the right-side optotype is set to a blue solid circle.
Step 102: collecting a first confirmation operation of a user, and determining a calibration mode according to the first confirmation operation, wherein the calibration mode comprises a first calibration mode and a second calibration mode;
in this embodiment, when performing the calibration of the optotype color, an operation prompt is given to the calibration interface, so that the user may perform an operation according to the operation prompt, for example, "please wear red-blue glasses, and cover the left eye and the right eye in sequence" is displayed on the calibration interface, and the left eye visual optotype and the right eye visual optotype are calibrated.
In this embodiment, the first confirmation operation of the user is collected, and a calibration mode is determined according to the first confirmation operation, where the calibration mode includes a first calibration mode and a second calibration mode, specifically:
collecting a first confirmation operation of a user, and determining the number of visible optotypes of the left eye and the number of visible optotypes of the right eye of the user according to the first confirmation operation;
and determining a calibration mode according to the number of the visible optotypes of the left eye and the number of the visible optotypes of the right eye.
In this embodiment, the RGB channel values of the optotype are adjusted so that the number of left-eye and right-eye visual optotypes of the user is one.
In this embodiment, when performing the visual standard calibration, the user covers the left eye after wearing the red-blue glasses according to the operation prompt, and views the screen through the single eye of the right eye, and confirms the number of visual targets of the right eye. The system acquires a first confirmation operation of a user, determines the number of visual targets of the right eye of the user through the first confirmation operation, enters a first calibration mode for the right eye if the number of the visual targets of the right eye is two, and confirms and acquires the number of the visual targets of the left eye if the number of the visual targets of the right eye is one.
In this embodiment, the calibration interface will be initialized after entering binocular vision training. First, the patient is asked to cover the left lens with his hand and ask the right eye to look at the screen: "only one circle", "two circles", if "two circles" are selected, entering a first calibration mode for the right ophthalmic lens; otherwise, the patient is asked to cover the right lens with his hand and ask the left eye to look at the screen: "only one circle", "two circles", if "two circles" are selected, the first calibration mode is entered for the left ophthalmic lens.
In this embodiment, the determining the calibration mode according to the number of visible optotypes for the left eye and the number of visible optotypes for the right eye specifically includes:
when the number of the visible optotypes of the left eye and the number of the visible optotypes of the right eye are both one, the calibration mode is a second calibration mode;
otherwise, the calibration mode is a first calibration mode.
In the present embodiment, the second calibration mode is entered only when the number of visible targets for the left eye and the right eye of the user is one.
In this embodiment, the number of visual targets visible to the left eye and the number of visual targets visible to the right eye of the user are determined through the first confirmation operation, so that whether the visual targets visible to the left eye and the right eye need to be calibrated or not is determined, and only one visual target can be seen by the left eye and the right eye under wearing of the red-blue glasses by means of respective calibration, so that the visual separation effect of the left eye and the right eye is improved, and the visual training effect is improved.
Step 103: when the calibration mode is a first calibration mode, responding to a first calibration operation of a user, and sequentially adjusting RGB channel values of the left visual target and the right visual target according to the first calibration operation until the RGB channel values of the left visual target and the right visual target respectively reach preset RGB channel values, and entering a second calibration mode;
in this embodiment, the responding to the first calibration operation of the user sequentially adjusts the RGB channel values of the left visual target and the right visual target according to the first calibration operation until the RGB channel values of the left visual target and the right visual target respectively reach the preset RGB channel values, and then enters a second calibration mode, specifically:
acquiring the number of visible optotypes of the left eye and the number of visible optotypes of the right eye of a user;
if the number of visible optotypes of the left eye and the number of visible optotypes of the right eye of the user are two, the first calibration operation adjusts the RGB channel values of the left optotype and the right optotype respectively;
if the number of visible optotypes of the left eye of the user is one and the number of visible optotypes of the right eye is two, adjusting the RGB channel value of the left optotype according to the first calibration operation;
if the number of the visible optotypes of the left eye of the user is two and the number of the visible optotypes of the right eye is one, adjusting the RGB channel value of the right optotype according to the first calibration operation;
until the RGB channel values of the left visual target and the right visual target respectively reach preset RGB channel values, so that the number of the visible visual targets of the left eye and the right eye of a user is one, and a second calibration mode is entered.
Referring to fig. 4, fig. 4 is a schematic diagram of a first calibration mode according to an embodiment of the invention.
In this embodiment, if the number of visible optotypes for the right eye is one, the right eye lens enters the first calibration mode, and after entering the first calibration mode, the calibration interface gives a corresponding operation prompt, so that the user calibrates the left optotype according to the operation prompt. For example, "left-side target color is brighter than background" and "left-side target color is darker than background" are displayed at the calibration interface. And collecting the operation of a user, and changing the RGB channel value of the left visual target according to the operation of the user.
In this embodiment, a movable progress bar is set on the calibration interface of the first calibration mode, and the user changes the RGB channel of the left visual target by moving the movable progress bar until the left visual target can be completely filtered by the red lenses in the red-blue glasses worn by the user, so that the visual target of the right eye of the user is only the right visual target.
In this embodiment, after the first calibration is completed for the right eye, if the number of visible optotypes for the left eye is two, a first calibration mode is performed for the left eye, and "the right optotype color is brighter than the background" and "the right optotype color is darker than the background" are displayed on the calibration interface. And changing the RGB channel value of the right visual target through the movable progress bar until the right visual target can be completely filtered by a blue lens in the red-blue glasses worn by the user, so that the visual target of the left eye of the user is only the left visual target.
In this embodiment, the movable progress bar actually changes the values of three color channels of R (red), G (green), and B (blue) of the optotype so that the three color channels are superimposed to obtain different colors. If the target to be calibrated is brighter than the background, the color is more similar to white RGB (255 ), and only the non-0 value in the RBG channel of the target to be calibrated is changed to be continuously reduced to be close to black RGB (0, 0) (the initialized RGB value of the red target is (255, 0), and the RGB value of the blue target is (0,0,255)). Similarly, if the optotype to be calibrated is darker than the background, the color of the optotype to be calibrated is more similar to that of black RGB (0, 0), and only the value of 0 in the RBG channel of the optotype to be calibrated is required to be changed at the same time, so that the value is increased continuously and is less towards white RGB (255 ).
If the visual target to be adjusted is red, the leftmost end of the movable progress bar is the color (255, 0) before adjustment of the circle, and the rightmost end of the movable progress bar is (255 ) dark or (0, 0) bright; similarly, if the target to be adjusted is blue, the leftmost end of the movable progress bar is the color (0,0,255) of the target before adjustment, and the rightmost end of the movable progress bar is (255 ) darker or (0, 0) lighter.
In this embodiment, by adjusting the RGB channel values of the left and right optotypes in the first calibration mode, the RGB channel values of the current left and right optotypes better conform to the red and blue glasses currently worn by the user, so as to improve the filtering effect of the red and blue glasses and improve the binocular vision splitting effect of the user.
Step 104: and when the calibration mode is a second calibration mode, collecting a second confirmation operation of a user, screening a first visual target according to the second confirmation operation, and adjusting the RGB channel value of the first visual target according to the RGB channel value of the calibration interface until the RGB channel value of the first visual target reaches a preset condition, so as to complete the color calibration of the visual target.
In this embodiment, the second confirmation operation of the collecting user screens out the first optotype according to the second confirmation operation, and adjusts the RGB channel value of the first optotype according to the RGB channel value of the calibration interface until the RGB channel value of the first optotype reaches a preset condition, so as to complete the color calibration of the optotype, specifically:
collecting a second confirmation operation of a user, comparing the display definition of the left visual target and the right visual target according to the second confirmation operation, and confirming the first visual target; the first visual target is a visual target with high imaging definition;
and adjusting the RGB channel value of the first visual target according to the RGB channel value of the calibration interface until the RGB channel value of the first visual target reaches a preset condition, so that the imaging definition of the left visual target is consistent with that of the right visual target, and the visual target color calibration is completed.

The RGB channel values of the clear circles are drawn toward the RGB channel values of the background color, i.e., the red circles raise the values of the blue channels, and the blue circles raise the values of the red channels. If the optotype to be adjusted is a red optotype, the leftmost end of the movable progress bar is the color (r, g, b) of the optotype before adjustment, and the rightmost end of the movable progress bar is (r, g, 255); similarly, if the visual target to be adjusted is a blue visual target, the leftmost end of the movable progress bar is the color (r, g, b) before adjustment of the visual target, and the rightmost end of the movable progress bar is (255, g, b). When moving to the far right, the optotype is basically in a complete disappearing state and is integrated with the background.
In this embodiment, through the second confirmation operation of the user, the imaging definition of the left visual target and the right visual target in the process of actually wearing the device is confirmed, so that the RGB channel values of the left visual target and the right visual target are adjusted, the imaging definition of the left visual target and the right visual target are basically consistent, the binocular vision of the user is balanced, the monocular inhibition caused by inconsistent imaging definition is avoided, and the effect of vision training is improved.
In another alternative embodiment, the user may choose directly by setting the stepwise RGB channel values to list the various adjusted optotypes. For example, when the red optotype is adjusted in the image balancing module, the (r, g, b), (r, g, b+10), (r, g, b+20), (r, g, b+30), (r, g, b+40), (r, g, b+50) are listed in units of 10 for the user to select, so that the optotype is closer to the background primary color.
Referring to fig. 6, fig. 6 is a schematic flow chart of a method for calibrating optotype color according to an embodiment of the invention.
