In the following embodiments, optional features and examples are provided in each embodiment at the same time, and the various features described in the embodiments can be combined to form multiple optional solutions, and each numbered embodiment should not be regarded as only for a technical solution.

Example 1

FIG. 1 is a flowchart of a vision detection method provided in Embodiment 1 of the present invention. The vision detection method provided by this embodiment can be applied to the situation of vision detection, for example, it is suitable for use of smart TVs, mobile phones, or computers with display functions. The case of electronic products for vision testing. The method can be implemented by the vision detection device provided by the embodiment of the present invention, specifically by hardware and/or software in the vision detection device, and the vision detection device can be integrated in the electronic product provided by the embodiment of the present invention, for example, integrated in a smart TV In electronic products with display functions such as computers, mobile phones or computers.

Referring to Figure 1, the vision detection method includes the following steps:

S110. In response to a user operation acting on the detection distance selection interface, determine a target detection distance and a first display parameter of an eye chart corresponding to the target detection distance.

In the embodiment of the present invention, a display module (such as an LCD display screen, an LED display screen, or an OLED display screen) of an electronic product can display a virtual vision chart, so as to simulate a real vision chart for vision detection. Due to the differences in the size specifications of the display modules, the types of eye chart sizes that can be displayed by display modules of different sizes are also different. For example, if the display module is a small-sized display screen, it can only display a small-sized eye chart. If it is a large-sized display screen, it can satisfy both the display of small-sized vision charts and the display of large-sized vision charts. Different sizes of vision charts have different detection distances. For example, a large-sized vision chart corresponds to a detection distance of 5m, a medium-sized vision chart corresponds to a detection distance of 2.5m, and a small-sized vision chart corresponds to a detection distance of 2.5m. The detection distance is 1.25m, which is not limited here.

In the detection distance selection interface displayed by the display module of the electronic product, at least one option that satisfies the detection distance corresponding to the displayed eye chart size can be provided, and the electronic product can receive the user operation acting on the detection distance selection interface, and select The detection distance indicated by the user operation is taken as the target detection distance, and the first display parameter of the eye chart corresponding to the target detection distance can be read from the preset storage space. Exemplarily, when the user clicks the button control corresponding to 2.5m on the detection distance selection interface, the electronic product can receive the user operation of clicking the button control, and use the 2.5m corresponding to the button control as the target detection distance, and can store it from the preset. Read the first display parameter of the eye chart corresponding to 2.5m in the space.

Optionally, in response to a user operation acting on the detection distance selection interface before the user operation, the method further includes: in response to a vision detection request, displaying a detection distance selection interface.

During standby or normal operation of the electronic product, a vision detection request, such as a voice vision detection request or a remote control vision detection request, can be received. When the electronic product receives the vision detection request, it can trigger and run the code program corresponding to the vision detection method provided by the embodiment of the present invention to display the detection distance selection interface (for example, a detection distance selection prompt box pops up), so that the user can detect the distance. Enter user actions in the distance selection interface.

S120. Collect a user position image, and adjust the user to a preset detection position according to the target detection distance, the first display parameter, and the user position image.

In this embodiment of the present invention, in response to a user operation acting on the detection distance selection interface, the electronic product may also enable an image acquisition module for the user's position image, for example, enable a camera group module including at least two cameras, and may also prompt the user to enter the camera. The range of image acquisition for the group. After collecting the user's position image through the camera group, the user's spatial position can be determined according to the spatial ranging algorithm of binocular/polyocular vision or the spatial algorithm based on fringe projection. A display parameter adjusts the user's position, so that the user can perform vision detection at the preset detection position, that is, the user can perform vision detection at the detection position that satisfies the target detection distance and the first display parameter, thereby improving the vision detection accuracy. .

In this embodiment, the process of adjusting the user's position according to the user's spatial position, the target detection distance, and the first display parameter may be the simultaneous adjustment of the user's horizontal position, vertical position and vertical depth from the center of the camera group, for example At the same time, it gives the distance that the user needs to move forward/backward, the distance to move left/right, and the distance to move up/down; it can also be the adjustment of the user's horizontal position, vertical position and vertical depth from the center of the camera group in turn. In addition, the order of adjusting the horizontal position, vertical position and vertical depth of the user from the center of the camera group in turn may be any order, which is not limited here.

Exemplarily, the process of sequentially adjusting the horizontal position, vertical position and longitudinal depth of the user from the center of the camera group may be: the electronic product first prompts the user according to the difference between the value of the longitudinal depth in the spatial position of the user and the value of the target detection distance. The user adjusts the vertical depth distance, such as walking forward to the camera group, or backing away from the camera group, etc.; after the user adjusts the vertical depth distance each time, the electronic product can re-determine the value of the vertical depth in the user's spatial position and the value of the vertical depth. When the difference between the target detection distances is smaller than the first preset value, it is considered that the user's longitudinal depth position adjustment is completed. After adjusting the position of the vertical depth, the electronic product can follow the difference between the value of the horizontal position/vertical position in the user's spatial position and the value of the horizontal position/vertical position of the eye chart on the screen in the first display parameter. value, prompting the user to adjust the horizontal position/vertical position, such as moving left/right, or moving up/down (for example, in a sitting or standing position), so that the user can look straight ahead on the eye chart, thus ensuring vision detection accuracy.

Optionally, the first display parameter includes center position coordinates; correspondingly, adjusting the user to a preset detection position according to the target detection distance, the first display parameter and the user position image, including: identifying user feature points in the user position image , and determine the three-dimensional position coordinates of the user's feature points; according to the target detection distance, the center position coordinates of the eye chart, and the three-dimensional position coordinates, the user is adjusted to the preset detection position.

In this embodiment, the center position coordinates of the eye chart can be considered as the pixel position coordinates of the center of the eye chart in the display module of the electronic product. Taking the center position of the image acquisition module as the origin, establish a reference three-dimensional coordinate system. For example, when the image acquisition module is arranged at the center position above the display module, the horizontal direction in the screen plane of the display module can be used as the X axis, the vertical direction as the Y axis, and the vertical direction as the Y axis. The direction of the screen plane is used as the Z axis. Further, it is possible to determine the transformation relationship between the pixel coordinate system of the display module and the benchmark three-dimensional coordinate system, and according to the transformation relationship between the pixel coordinate system and the benchmark three-dimensional coordinate system, it can be determined that the center of the eye chart is located at the positional coordinates under the benchmark three-dimensional coordinate system, and the The axis of the position coordinate that usually represents the longitudinal depth has a value of zero. In addition, the target detection distance can be considered as the distance from the plane formed by the horizontal and vertical directions of the reference three-dimensional coordinate system, and can be expressed as a numerical value of the axis of the vertical depth in the reference three-dimensional coordinate system.

Among them, the user feature points in the user location image are identified, for example, the user face features in the user image are identified through a face recognition algorithm, and the user's eyes may be preferentially selected as the user feature points. The three-dimensional position coordinates of the user feature points can be determined according to the user position image, and the three-dimensional position coordinates can be considered as coordinates in the reference three-dimensional coordinate system corresponding to the image acquisition module.

By comparing the value of the horizontal axis, the value of the vertical axis and the value of the longitudinal depth axis in the three-dimensional position coordinates of the user feature point with the value of the horizontal axis in the reference three-dimensional coordinate system, the center of the eye chart is located in the reference three-dimensional coordinate system. , the value of the axis in the vertical direction, and the value of the axis of the longitudinal depth of the target detection distance in the reference three-dimensional coordinate system, can provide the adjustment prompt information for the three-dimensional position coordinates of the user's feature points. The user can adjust the position based on the adjustment information to adjust to the preset detection position, so as to meet the requirements of vision detection and improve the accuracy of vision detection.

Optionally, after collecting the user position image, the method further includes: when it is recognized that there is an eye blocker in the user position image, prompting the user to remove the eye blocker. The user position image may also be used to identify whether the user's eyes are blocked by the eyes, for example, whether the user's eyes are wearing glasses, sunglasses, or the like. And in order to detect the user's naked eyesight, when it is recognized that there is eye occlusion in the user's position image, the user can be prompted to remove the eye occlusion, for example, the user can be prompted to take off the glasses by playing a prompt sound through the speaker or displaying prompt text through the display model. Wait.

S130. Detect ambient light, determine a second display parameter of the display screen according to the ambient light, and display the eye chart in a first mode according to the first display parameter and the second display parameter.

When performing vision detection, the external ambient light will affect the vision detection result to a certain extent. For example, when the ambient light is too dark, it is not conducive to the vision detection. The ambient light may be detected based on the image acquisition module, or the ambient light may be detected by a light sensor. After further detecting the ambient light, the second display parameter of the display screen can be determined according to the pre-stored corresponding relationship between the ambient light and the second display parameter, for example, determining the brightness, color temperature, contrast, and sharpness of the display screen. Adjusting the display screen according to the second display parameter can reduce the influence of ambient light on the vision detection result to a certain extent, and improve the vision detection accuracy.

Optionally, the first display parameter includes size and center position coordinates, and the second display parameter includes brightness and color temperature; correspondingly, performing a first mode display on the vision chart according to the first display parameter and the second display parameter, including: Determine the display position and display size of each optotype in the eye chart; determine the type of optotype at each display position, set the optotype of the type to the corresponding display size, and perform the first step for each optotype. Mode display; adjusts the display to the determined brightness and color temperature.

In this embodiment, the display brightness and color temperature of the display module can be adjusted according to the second display parameter, and then the eye chart can be displayed according to the first display parameter; The second display parameter adjusts the display brightness and color temperature of the display module; the eye chart can also be displayed according to the first display parameter, and the display brightness and color temperature of the display module can be adjusted according to the second display parameter.

The process of adjusting the display brightness and color temperature of the display module according to the second display parameter may be that the display module first displays the preset brightness and color temperature, and then calibrates according to the brightness and color temperature in the second display parameter. Wherein, the process of displaying the eye chart according to the first display parameter may be, according to the size and center position of the eye chart in the first display parameter, to determine the display position of the optotype corresponding to each row and each column in the eye chart, and the position of each display position. The display size of the optotype; for each display position, the optotype type can be randomly selected (taking the "E" optotype as an example, the optotype with the opening up/down/left/right can be randomly selected), and then according to the corresponding display position The display size setting selects the size of the optotype, and fills the optotype with the set size to the display position, thereby realizing the display of each optotype in the eye chart. In addition, the display mode may include displaying the font, shape, color and/or effect of the optotype, and the effect may be, for example, normal, highlight or flashing, and the first mode display may be, for example, a normal effect display.

S140: Select at least one optotype to be determined in the eye chart in turn, display the currently selected optotype to be determined in the second mode, and receive the determination result input by the user.

In the embodiment of the present invention, after the vision chart is displayed on the vision detection interface of the display module of the electronic product, the optotypes to be determined in the vision chart can be randomly selected in descending order of the optotypes, and the selected optotypes to be determined can be selected at random. A second mode display is possible. Among them, the second mode is different from the first mode, for example, the effect is highlighted first and then restored to the normal effect display, or the effect display is flashed first and then restored to the normal effect display, which is intended to prompt the user for the pending view of the special display. mark to judge.

Optionally, receiving the determination result input by the user includes: receiving the gesture determination result, the voice determination result and/or the remote control determination result input by the user.

Among them, the electronic product can collect and recognize the gesture judgment result input by the user through the image acquisition module, and can also receive the gesture judgment result input by the user through the sensing device of the device such as the handle paired with the electronic product; the voice receiving module (such as a microphone etc.) to receive the voice judgment result input by the user; the remote control judgment result input by the infrared remote control can be received through the infrared receiving module, the remote control judgment result input by the Bluetooth remote control can also be received through the Bluetooth receiving module, and the remote control judgment result input by the Bluetooth remote control can also be received through the application software. The software interface receives the remote control judgment result input by the application software remote control, etc.

Exemplarily, the electronic product can recognize the pointing of the finger/arm in the image of the user's finger/arm collected by the image acquisition module, or receive the handle orientation identified by the gyroscope in the handle paired with the electronic product, and determine the direction of the pointing or the orientation. The text information is used as the gesture judgment result; the electronic product can recognize the user's voice containing the judgment words "up, down, left, right", such as "up", "down", "left", "right" collected by the microphone, and use the The text information of the recognized judgment word is used as the voice judgment result; the electronic product can parse the infrared, Bluetooth or data signals received by the infrared module, the Bluetooth module or the software interface, and can use the text information of the analysis result as the judgment result of the remote control.

S150, analyze the judgment result to obtain a vision detection result, and perform an eye prompting according to the vision detection result.

In the embodiment of the present invention, during the vision detection process, each time a user-input determination result for an optotype to be determined is received, the determination result can be analyzed in real time; A unified analysis is performed on the determination results of one or more (usually multiple) optotypes to be determined. Preferably, the determination result can be analyzed in real time, so that when the user makes a wrong determination of the optotype of a certain size, the selection of the optotype to be determined with a smaller size is stopped, which saves the detection time and improves the detection efficiency. In addition, after obtaining the vision detection result of one eye of the user, step S140 may also be repeated to perform vision detection of the other eye.

Specifically, analyzing the judgment result may include: when the judgment result is the gesture judgment result, judging whether the text information of the judgment direction in the gesture judgment result is consistent with the text information of the preset direction of the target to be judged; if so, the judgment is successful; if Otherwise, the judgment fails; when the judgment result is the voice judgment result, judge whether the text information of the judgment word in the voice judgment result is consistent with the text information of the preset judgment word of the visual target to be judged, if so, the judgment is successful, otherwise the judgment fails; when the judgment When the result is the judgment result of the remote control, it is judged whether the text information of the analysis result is consistent with the preset text information of the optotype to be judged, and if so, the judgment is successful; otherwise, the judgment fails.

Specifically, the eye prompting can be performed by displaying pictures and texts on the display module, or by playing the voice through the speaker module to perform the eye prompting, or by pushing the prompt information to the setting of the user who is currently detecting vision application software account to perform eye prompting. And the content of the prompt may be, reminding the user of the duration of using the electronic product, reminding the user to rest, reminding the user to go to a hospital or an optical shop for a corresponding eye examination, and the like.

Optionally, analyze the judgment result to obtain the vision detection result, including: comparing the judgment result with the standard judgment result to determine the user's vision value; and visual acuity change trend as the result of visual acuity test.

In this embodiment, the visual acuity value of the user may be determined according to the determination accuracy of the to-be-determined optotype corresponding to the visual acuity value. Specifically, the optimal visual acuity value may be selected as the user's visual acuity value from a plurality of visual acuity values whose determination accuracy is higher than the preset accuracy rate. Vision value. Exemplarily, the preset accuracy rate is 80%, assuming that the user is in the process of detecting the visual acuity of the left eye, the determination accuracy rate of the to-be-determined optotype corresponding to the visual acuity value of 4.9 is 100%, and the determination accuracy of the to-be-determined optotype corresponding to the visual acuity value of 5.0 is 100%. is 80%, and the determination accuracy of the optotype to be determined corresponding to the visual acuity value of 5.1 is 20%, it can be considered that the visual acuity value of the user's left eye is 5.0. Further, the historical visual acuity value of the user can be read out from the preset storage space, and compared with the visual acuity value obtained this time, to determine the visual acuity change trend, such as the increase of myopia, and the visual acuity change trend. The format can be graphs, tables, or text, etc.
