[0037] Figure 3 It is a schematic diagram of the hardware structure of a computer device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] At present, the domestic and foreign ophthalmometer markets still generally rely on traditional physical buttons and manual operation modes, which require professional assistance and are complex and inefficient in accurately tracking the position of the human eye and pupil. Although fully automatic ophthalmometers have appeared on the market, which can automatically measure the refractive power of the human eye with one-button start, this process still requires manual assistance to adjust the height of the forehead support, and has not yet fully achieved unattended automated operation.

[0040] According to an embodiment of the present invention, an embodiment of an intelligent self-service optometry system is provided, and the system includes:

[0041] A lifting platform 2, which can be adjusted and moved in up and down directions and in front and back directions, and is used to place an ophthalmometer 3;

[0042] An image acquisition device is provided on one side of the detection window of the ophthalmometer 3 for capturing a face image; a pupil imaging lens 4 is provided in the detection window for capturing a pupil image; a forehead support bracket 6 with adjustable height is provided on the ophthalmometer 3, the forehead support bracket 6 is located in front of the imaging lens 4, a forehead support pressure sensor is installed on the forehead support bracket 6, and the ophthalmometer 3 can be adjusted and moved in the up-down, left-right, and front-back directions;

[0043] A measuring chair 1, on which a pressure sensor is installed;

[0044] The control unit is used to control the positions of the forehead support bracket 6 and the ophthalmometer 3 to acquire the pupil image of the target object according to the face image acquired by the image acquisition device when receiving the trigger signal of the pressure sensor 5.

[0045] like Figure 1As shown, the target object first sits on the measuring chair 1. After the pressure sensor 5 arranged on the measuring chair 1 detects the pressure signal, the lifting platform 2 is first moved forward to the first preset position, and the ophthalmometer 3 starts the voice prompting the measured person to sit up straight and look forward. The imaging lens 4 placed under the measuring window of the ophthalmometer captures the face image of the target object, and the pupil position is located by using the preset deep learning algorithm. The relative position relationship between the pupil position and the detection window of the ophthalmometer 3 is analyzed to determine whether the pupil is located in the preset ideal area, that is, the first standard position. If not in the first standard position, the distance between the pupil position and the first standard position is calculated, and The mobile lifting platform 2 reaches this distance and reaches the second preset position to eliminate the height difference between different users. Then, when the target object places the head on the forehead support bracket 6, the forehead support pressure sensor responds immediately, and the system immediately enters the fine adjustment stage. According to the first distance between the pupil and the chin, the forehead support bracket 6 is intelligently lifted to the preset height to ensure that the user's head is in the best comfort and sight angle. Then, the system further analyzes the second standard position deviation between the pupil and the imaging lens 4 in the ophthalmometer 3, and drives the ophthalmometer 3 to perform subtle up and down, left and right, and front and back adjustments until the pupil is aligned with the imaging lens 4 to achieve the best focus state.

[0046] After completing these preparation steps, the system enters the automatic optometry process. The refractive power measurement results corresponding to the two eyes are obtained. This process is not only efficient, but also does not require the direct participation of professionals, replacing manual operations, reducing human errors, and realizing unattended and fully intelligent and self-service optometry process.

[0047] In some optional implementations, the ophthalmometer 3 further includes a voice playback unit, which plays a prompt recording when receiving a trigger signal from the pressure sensor.

[0048] By adding a voice playback unit for playing a prompt recording, when the target object sits on the measuring chair and the pressure sensor on the measuring chair detects a pressure electrical signal, the control unit adjusts the lifting platform to move to the first preset position, and then the ophthalmometer prompts the target object to sit up straight and look forward through the voice playback unit.

[0049] The intelligent self-service eye test system in this embodiment is presented in the form of functional units, where the units refer to ASIC (Application Specific Integrated Circuit) circuits, processors and memories that execute one or more software or fixed programs, and / or other devices that can provide the above functions.

[0050] According to an embodiment of the present invention, an embodiment of an intelligent self-service eye examination method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0051] In this embodiment, an intelligent self-service optometry method is provided, which is applied to the above system. Figure 2 is a flow chart of an intelligent self-service optometry method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0052] Step S201: When it is detected that the pressure sensor on the measuring chair generates a pressure signal, the lifting platform is adjusted to move to a first preset position.

[0053] Specifically, when the system is started, the pressure sensor on the measuring chair begins to continuously monitor whether there is a pressure change. When the user sits down, the pressure sensor senses the pressure change and then generates a pressure electrical signal. The electrical signal generated by the pressure sensor is transmitted to the control unit via wires or wirelessly.

[0054] Step S202: acquiring a face image acquired by an image acquisition device to determine the pupil position of the target object.

[0055] Specifically, when the lifting platform has been adjusted to the first preset position, the control unit will send a start signal to the image acquisition device, and the imaging lens module placed below the measurement window of the ophthalmometer will capture the face image. The field of view of the imaging lens is greater than 50 degrees. The algorithm will perform face recognition and feature extraction to identify key areas of the face, such as the eyes, nose, mouth, etc. In particular, the algorithm will focus on the eye area and accurately locate the pupil through edge detection, morphological operations and other methods.

[0056] Optionally, if problems are found during image processing, such as blurred images, incomplete face capture, etc., the system will provide feedback to the user through display screens, sound prompts, etc., and ask the user to readjust their posture or position.

[0057] In some optional implementations, after the above step S202, the following further includes:

[0058] According to the pupil position, the lifting platform is adjusted to the second preset position so that the pupil position is located at the first standard position.

[0059] Specifically, after obtaining the pupil position according to the above step S202, the relative position relationship between the pupil position and the detection window of the ophthalmometer is analyzed to determine whether the pupil is located in a preset ideal area, that is, the first standard position. If it is not in the first standard position, the distance between the pupil position and the first standard position is calculated, and the lifting platform is moved to this distance to reach the second preset position to eliminate the height difference between different users.

[0060] Optionally, when the lifting platform reaches the second preset position, the system may capture the facial image again through the image acquisition device to verify whether the pupil is already in the ideal area. If the verification result meets the requirements, the system will continue with the subsequent eye examination steps; if it does not meet the requirements, it may be necessary to readjust the position of the lifting platform until the requirements are met.

[0061] Step S203, when a pressure signal generated by a forehead support pressure sensor on the forehead support bracket is detected, the forehead support bracket and the ophthalmometer are adjusted to a preset position according to the pupil position.

[0062] Specifically, when the user places the head on the forehead support, the forehead support pressure sensor senses the pressure change and generates a pressure electrical signal. This signal is transmitted to the control unit through a wire or wirelessly, and the control unit extracts the pupil position data from the face image obtained in the previous step S202. These data are usually expressed in the form of coordinates and are clearly marked in the image coordinate system or the coordinate system of the ophthalmometer.

[0063] Furthermore, the control unit uses a built-in algorithm to calculate the distance and direction that need to be adjusted according to the pupil position data and the preset optimal position relationship between the ophthalmometer and the pupil, and adjusts the forehead support bracket and the ophthalmometer to the preset position.

[0064] In some optional implementations, the above step S203 includes:

[0065] According to a first distance between the pupil position and the chin, adjusting the forehead support bracket so that the first distance is a preset value;

[0066] According to the deviation between the pupil position and the second standard position, the ophthalmometer is adjusted to make the pupil position be located at the second standard position.

[0067] Specifically, when the forehead support pressure sensor detects a pressure electrical signal, the face image captured by the image acquisition device is first used to identify the pupil position using image processing technology. At the same time, the system also identifies the position of the chin and calculates the first distance between the pupil position and the chin, and compares it with a preset optimal distance preset value. If the first distance is not equal to the preset value, the control unit will send a signal to the adjustment mechanism of the forehead support bracket to make it rise or fall until the first distance reaches the preset value.

[0068] Further, after the forehead support bracket is adjusted, the system confirms the pupil position again and compares it with the second standard position in the ophthalmometer detection window, usually the best focus point of the pupil imaging lens, and calculates the deviation between the pupil position and the second standard position.

[0069] Further, according to the size and direction of the deviation, the control unit will send a signal to the adjustment mechanism of the ophthalmometer to make fine adjustments in the up-down, left-right or front-back directions. When the pupil position is precisely aligned with the second standard position, the adjustment stops.

[0070] Step S204, sequentially adjusting and measuring the diopter corresponding to the single eye, and obtaining the measurement results corresponding to the single eye respectively.

[0071] Specifically, the pupil imaging lens is started, and the target object looks at a specific point or cursor in the lens to ensure that the pupil image is clear. The pupil images of the tested eyes are collected in turn, and the appropriate refractive measurement mode is selected, which usually includes the measurement of sphere (Sphere, S), cylinder (C) and axis (Axis, A). Specifically, sphere measurement: measures the refractive power of the eyeball in the horizontal direction, which is used to correct myopia or hyperopia; cylinder measurement: measures the refractive power of the eyeball in the vertical or oblique direction, which is used to correct astigmatism; axis measurement: determines the axis of astigmatism, that is, the direction in which the astigmatism is most obvious.

[0072] Furthermore, the ophthalmometer will automatically calculate the refractive power of the measured eye based on the pupil image and the built-in algorithm. After the measurement of a single eye is completed, the other eye is switched to perform the same process as above. After the measurement of both eyes is completed, the ophthalmometer will display the measurement results including the refractive power data of both eyes, which may include spherical power, cylindrical power and axis position.

[0073] In summary, in the intelligent self-service eye test method provided by the embodiment of the present invention, when the target object sits on the measuring chair, the pressure sensor arranged on the measuring chair detects the pressure signal and transmits the pressure electrical signal to the control unit, and the control unit controls the lifting platform to move forward to the first preset position to ensure that the ophthalmometer is in an appropriate height range. Then, the imaging lens module placed below the measuring window of the ophthalmometer quickly captures the face image of the target object, and locates the pupil position using a preset deep learning algorithm. Then, by analyzing the relative position relationship between the pupil position and the detection window of the ophthalmometer, it is determined whether the pupil is located in the preset ideal area, that is, the first standard position. If not in the first standard position, the distance between the pupil position and the first standard position is calculated, and the lifting platform is moved to this distance to reach the second preset position to eliminate the height difference between different users. Once the user places the head on the forehead rest bracket, the forehead rest pressure sensor responds immediately and the system enters the fine adjustment stage. According to the first distance between the pupil and the chin, the forehead rest bracket intelligently rises and falls to the preset height to ensure that the user's head is in the best comfort and sight angle. Subsequently, the system further analyzes the second standard position deviation between the pupil and the pupil imaging lens in the ophthalmometer, and drives the ophthalmometer to make subtle up and down, left and right, and front and back adjustments until the pupil is aligned with the imaging lens to achieve the best focus state.

[0074] After completing these preparation steps, the system enters the automatic optometry process. First, for each eye of the target object, the optometry instrument emits specific light or patterns in turn, and by capturing the subtle reaction of the pupil, accurately calculates the refractive power data, including spherical power, cylindrical power and axis information, and then switches to the other eye and repeats the above operation process to obtain binocular refractive power measurement results. This process is not only efficient, but also does not require the direct participation of professionals, replacing manual operation, reducing human errors, and realizing unattended and fully intelligent and self-service optometry process.

[0075] In some optional implementations, after the lifting platform is adjusted to move to the first preset position, the ophthalmometer performs voice broadcasting to prompt the target object to complete the preset voice instruction.

[0076] By adding a voice playback unit for playing a prompt recording, when the target object sits on the measuring chair and the pressure sensor on the measuring chair detects a pressure electrical signal, the control unit adjusts the lifting platform to move to the first preset position, and then the ophthalmometer prompts the target object to sit up straight and look forward through the voice playback unit.

[0077] Optionally, before adjusting the lifting platform to move to the first preset position, the ophthalmometer plays a preset welcome message and operation instructions through the voice playback unit, such as: "Welcome to the intelligent self-service optometry system, please sit on the measuring chair.".

[0078] In some optional implementations, after the detection is completed and the measurement results are obtained, the lifting platform, the ophthalmometer and the forehead support bracket are reset so that the lifting platform, the ophthalmometer and the forehead support bracket return to the initial measurement position.

[0079] The control unit controls the lifting platform to descend to the initial position, and the ophthalmometer and the forehead support bracket are also automatically adjusted to the initial measurement state, including the up and down, left and right, front and back positions of the ophthalmometer and the height of the forehead support bracket.

[0080] Optionally, after the reset is completed, the system may prompt the user through voice or display: "The eye test is completed, the system has been reset, thank you for your use."
