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 visual adaptation checking method according to an embodiment of the present invention, including steps 101 to 103, specifically as follows:
step 101: responding to control operation input by a user, determining an inspection mode according to the control operation, and setting the initial brightness of a first visual target according to the inspection mode; wherein the inspection mode includes: a brightness discrimination mode and a dark adaptation discrimination mode;
in this embodiment, before the visual adaptation is checked, a virtual reality game scene is created by VR equipment, an empty object is added, the object is named as a brightness controller, and a parallel light source is added to the scene. The light intensity of the brightness controller is adjusted to the darkest level (darkroom brightness can be adjusted according to actual conditions), and a real darkroom scene is simulated. An object was added 2m (inspection distance) in front of the user's field of view, named wall, and an object 30cm x 10cm was added in the center of the wall, named first optotype.
In this embodiment, before the control operation in response to the user input, determining the inspection mode according to the control operation, the method further includes:
calculating gray value level of the color according to RGB channel value of the color and a proportional linear interpolation method;
sequencing the gray value levels according to the RGB channel values, and setting a gray level table; the gray level table comprises a plurality of gray levels, wherein the lowest gray level represents the darkest brightness, and the highest gray level represents the brightest brightness.
In the present embodiment, for the first optotype used for the visual adaptation inspection, 16 gray levels are set from light to dark, and the value of each gray level of the first optotype may be set in order from low to high, for example, from 0 to 15, respectively representing 16 gray levels, where 0 represents the darkest gray and 15 represents the brightest gray. In Unity3D, gray scale setting can be achieved by setting color attributes of element materials, and values of three channels R, G, B of colors can be set to be the same value to represent brightness of gray scale.
In this embodiment, the gradation values of the remaining colors are calculated by determining the RGB channel values of the lowest-level gradation value and the highest-level gradation value according to the proportional linear interpolation method. Specifically, the darkest gray level of the number is 0.08cd/m2, and the color may be set to (0.08,0.08,0.08), and the values representing the three channels of RGB are the same, and are all 0.08. The brightest gray level of the number is 2.51cd/m2, the color can be set to 2 (. 51,2.51,2.51). The setting of the rest gray values can calculate corresponding RGB values (0.08, 0.10, 0.13, 0.16, 0.20, 0.25, 0.32, 0.40, 0.50, 0.63, 0.79, 1.00, 1.26, 1.58, 2.00, 2.51) according to the proportional linear interpolation mode.
In this embodiment, the inspection mode of the visually adapted inspection is determined by the control operation of the user, and before the control operation is input by the user, the inspection interface gives an inspection mode selection guide in which the brightness discrimination mode is a sequential mode of the brightness of the first optotype from brightest to darkest for inspecting the brightness discrimination capability of the user. The dark adaptation discrimination mode is a sequential mode of the first optotype from darkest to brightest in brightness for checking the user's dark adaptation capability. The two modes differ in examination effect, and the brightest to darkest mode can better examine the response speed and the brightness discrimination capability of the subject, and the darkest to brightest mode can better examine the dark adaptation capability and the response threshold of the subject.
In this embodiment, after the control operation in response to the user input, determining the inspection mode according to the control operation further includes: obtaining user information, wherein the user information comprises optimal corrected vision, and setting the size of a first visual target according to the optimal corrected vision; setting the initial brightness of the first optotype according to the checking mode;
when the inspection mode is a brightness discrimination mode, setting the initial brightness to be the highest gray level; when the inspection mode is a dark adaptation discrimination mode, the initial brightness is set to a lowest gray level.
In this embodiment, a plurality of gray scales are set through the RGB values of the colors, so that the brightness change of the first optotype in the training process can be sequentially changed step by step along with the gray scale table, so that the overlarge gray scale change is avoided, and the visual adaptation is not accurately checked.
In this embodiment, since the requirements of users of different ages on the size of the optotype may be different, the elderly need a larger optotype to better recognize, while the young has a relatively smaller requirement on the size of the optotype; some ocular disorders may affect the vision of the subject, and the size of the optotype may need to be adjusted to suit the actual situation. The vision requirements vary from job to job, such as the driver's need for better distance vision and the computer worker's need for better near vision. Therefore, the basic information of the user needs to be acquired, the basic information at least comprises the optimal corrected vision of the user, the size of the first visual target is adjusted according to the optimal corrected vision, and the user can manually adjust the size of the first visual target through keys according to the professional characteristics and actual requirements of the user.
In this embodiment, after the determination of the inspection mode according to the control operation, it further includes:
initializing elements in a training scene according to an inspection task, wherein the inspection task at least comprises element identification and direction identification;
when the inspection task is element identification, the first visual target comprises a first element and a second element, and the first element and the second element are initialized; wherein the first element and the second element have the same size and brightness;
when the checking task is direction identification, the first visual target comprises a first element, and the first element is initialized; wherein the first element has directional directivity.

In the present embodiment, the inspection task includes element discrimination and direction discrimination. In the element identification task, the first optotype includes two elements, and the elements may be any one of numbers, letters, patterns, and the like. Taking the elements as numbers, as shown in fig. 2, in the direction distinguishing task, the first optotype only includes one element with a direction indicator, as shown in fig. 3, and the first optotype may be set as a C-word optotype with a random direction.
Step 102: iteratively adjusting the element content of the first visual target and the brightness of the first visual target, judging the correctness of the current user operation according to the current element content and the checking task after each adjustment until the preset times of the checking task are met, and outputting all judgment results; the brightness of the first optotype is adjusted according to a preset gray level table and user operation of the last iteration during each iteration;

if the checking task is direction identification, iteratively and randomly adjusting the direction of the first element;
and adjusting the brightness of the elements in the first optotype according to the user operation and the check mode in each iteration.
In this embodiment, after the visual adaptation inspection is started, the element content of the first optotype and the brightness of the first optotype are iteratively adjusted. If the checking task is element identification at this time, randomly changing the contents of the first element and the second element when each iteration is adjusted, and judging whether the first element and the second element are identical according to user operation. The method comprises the following steps: in each element change, recording a start time A, a user needs to judge according to the content of a first element and a second element in a first visual target, recording a judging time B, and if the numbers in the first element and the second element are the same, pressing a left direction key or an upper direction key of a handle, and if the numbers are different, pressing a right direction key or a lower direction key of the handle. Two buttons "same" and "different" may also be placed in the scene to allow the user to select the judgment.
If the checking task at this time is direction discrimination, the direction of the first element is randomly changed during each iterative adjustment, and whether the user operation is correct or not is judged, specifically: and judging the direction of the C-shaped optotype. In each element change, the recording start time a, as shown in fig. 2, the user needs to observe the up, down, left, and right directions of the first visual target and press the direction key to make a judgment, and the recording judgment time B.
In this embodiment, the eye movement track of the subject is recorded in real time at the beginning of each iterative adjustment, and whether the subject is seriously subjected to the examination feedback can be determined whether the subject is in the threshold range of the examination optotype.
In this embodiment, the adjusting the brightness of the element in the first optotype according to the user operation and the inspection mode in each iteration specifically includes:
when the correctness of the user operation reaches the preset times in the iteration process, gradually adjusting the brightness of the elements in the first visual target according to a preset gray level table;
when the inspection mode is a brightness discrimination mode, the gray level of the element brightness is reduced; when the inspection mode is a dark adaptation discrimination mode, the gray level of the element brightness is turned up.
In this embodiment, when the user performs the visual adaptation inspection starting from the initial brightness, 3 iterative adjustments are required for each gray level of the first optotype, and the subject automatically jumps to the next gray level inspection after making 3 judgments. In each iterative adjustment, the gray value is displayed according to the preset value, and the content of the checked optotype is randomly displayed again.
In this embodiment, according to different inspection modes, the content and brightness level of the first optotype in the inspection task are changed multiple times and step by step, so that the user performs the inspection task in the gradually changed brightness, thereby gradually adjusting the adaptability of the eyes of the user, and performing the inspection of visual adaptation on both eyes of the user.
