[0002] In ophthalmological clinical practice, accurate eye examination of patients is crucial because it is directly related to the choice of treatment plan and the final treatment effect. However, many ophthalmic examination items, such as keratometric measurement, astigmatism measurement, fundus photography, etc., require the patient's head to be kept in a specific positive position. Any tilt of the head may lead to inaccurate measurement of corneal curvature and astigmatism axis, resulting in pseudorotation. These errors will not only mislead the doctor's diagnosis, but also lead to improper selection of treatment plans, ultimately affecting the treatment effect.

[0003] In the traditional examination process, in order to ensure that the patient's head is in the correct position, the doctor or technician usually needs to adjust the patient's head position before measurement to ensure that the central reflection points of the patient's cornea are on the same horizontal line.

The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0025] To facilitate understanding of the embodiments of the present application, first Figure 1 Detailed description. Figure 1 The structural schematic diagram of an adjustment system 100 of a head alignment fixing device for ophthalmic examination in an embodiment of the present invention is shown. The adjustment system 100 of a head alignment fixing device for ophthalmic examination in this embodiment mainly comprises: a head alignment fixing device 110, an image acquisition device 120 and a control and adjustment device 130; the head alignment fixing device 110 is connected to the image acquisition device 120; the head alignment fixing device 110 and the image acquisition device 120 are respectively connected to the control and adjustment device 130; wherein,

[0026] The image acquisition device 120 is used to acquire the eye image of the patient in the head alignment fixation device 110 in real time.

[0027] The control and adjustment device 130 is used to determine the patient's head position based on the eye image, and control the head position fixing device 110 to adjust according to the head position determination result.

[0028] In this embodiment, the eye image is an image of the eye position obtained by real-time acquisition of the image acquisition device by aiming at the head of the patient to be subjected to ophthalmological examination and fixed in the head correction fixing device. The image acquisition device may be a camera module, and the camera module includes a camera device, a storage device and a processing device. The camera device includes but is not limited to: a camera, a video camera, a micro camera, a camera module integrated with an optical system or a CCD chip, a camera module integrated with an optical system and a CMOS chip, etc.

[0029] Furthermore, the image acquisition device may be one or more, that is, one image acquisition device is aligned with the head fixation device to acquire the patient's eye image, or multiple image acquisition devices are aligned with the head fixation device to acquire the patient's eye image. The installation positions of the multiple image acquisition devices may be different, and the image acquisition areas of the image acquisition devices may have overlapping positions or may not overlap. In addition, a spare image acquisition device may be provided in case one of the image acquisition devices is damaged, so as not to affect the real-time acquisition of the eye image.

[0030] It should be understood that the "eye image" mentioned in this embodiment includes but is not limited to: static images, dynamic images or videos, etc. Static images can be in jpg, jpeg, tif, png and other formats; dynamic images can be in gif format; videos include mkv, mp4, avi, mov and other types.

[0031] In some examples, the control and adjustment device in the embodiment of the present application can be a controller such as ARM (Advanced RISC machines), FPGA (Field Programmable Gate Array), SoC (System on Chip), DSp (Digital Signal Processing) or MCU (Microcontroller Unit); it can also be a desktop computer, a laptop computer, a tablet computer, a smart phone, a smart bracelet, a smart watch, a smart helmet, a smart TV, a personal digital assistant (Personal Digital Assistant, referred to as PDA), etc.; it can also be a cloud server, which can be arranged on one or more physical servers according to various factors such as function and load, or it can be composed of distributed or centralized server clusters, which is not limited in this embodiment. In this embodiment, the control and adjustment device is preferably a microprocessor, which can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components, and is the operation control part of the microcomputer. The microprocessor has the advantages of small size, light weight and easy modularization.

[0032] In one embodiment, in combination Figure 2 It is explained that the control and adjustment device 130 includes:

[0033] An image recognition unit 131 is used to perform recognition processing on the eye image based on an image recognition algorithm to obtain a recognition result of the central reflective point of the cornea of ​​both eyes;

[0034] An angle calculation unit 132, connected to the image recognition unit 131, is used to calculate the tilt angle of the central reflective point of the cornea of ​​both eyes according to the coordinate information of the recognition result of the central reflective point of the cornea of ​​both eyes;

[0035] The comparison and judgment unit 133 is connected to the angle calculation unit 132, and is used to judge whether the tilt angle meets the preset horizontal requirement; if it meets the preset horizontal requirement, it is judged that the patient's head is in the correct position; if it does not meet the preset horizontal requirement, it is judged that the patient's head is not in the correct position.

[0036] Specifically, the control and adjustment device 130 includes an image recognition unit 131, an angle calculation unit 132, and a comparison and judgment unit 133, and the image recognition unit 131, the angle calculation unit 132, and the comparison and judgment unit 133 are electrically connected in sequence. It should be noted that the image acquisition device 120 transmits the real-time acquired eye image to the control and adjustment device 130, and the control and adjustment device 130 receives the eye image for processing, and after processing, sends a control signal to the head alignment fixing device 110, and the head alignment fixing device 110 adjusts according to the control signal to make the patient's head in the correct position.

[0037] It should be understood that the image recognition algorithm in this embodiment includes an edge detection algorithm, a shape recognition algorithm, a feature extraction and matching algorithm, a deep learning target detection algorithm, etc. The image recognition algorithm includes, but is not limited to: Sobel algorithm, Prewitt algorithm, Canny algorithm, Hough transform algorithm, BRIEF algorithm, BRISK algorithm, ORB algorithm, R-CNN algorithm, SPP-Net algorithm, Fast RCNN algorithm, R-FCN algorithm, Mask R-CNN algorithm, Cascade R-CNN algorithm, TridentNet algorithm, SSD series algorithm, YOLOX algorithm, YOLOv series algorithm, RetinaNet algorithm, CornerNet algorithm, CenterNet algorithm, etc. The image recognition algorithm can be selected and adjusted differently according to the actual situation, and this embodiment does not limit it.

[0038] It should be noted that the image recognition algorithm provides high efficiency, consistency and real-time processing capabilities by automatically and accurately analyzing image data, while reducing labor costs and improving the accuracy of decision-making. The image recognition algorithm is highly scalable and can adapt to different data sets and image types. The use of the image recognition algorithm in this embodiment improves the recognition speed and accuracy of the image, and has better detection performance for small targets.

[0039] In this embodiment, the central reflective point of the cornea of ​​both eyes is the reflective point in the center of the cornea of ​​both eyes of the patient when the patient is looking straight ahead. When the central reflective points of the cornea of ​​both eyes are not in the same horizontal plane, it is determined that the patient's head is tilted. At this time, the patient's head needs to be adjusted to be in the right position before an ophthalmological examination can be performed. In this embodiment, the image recognition unit 131 detects the eye image through an image recognition detection algorithm to obtain the central reflective point of the cornea of ​​the patient's two eyeballs, that is, the central reflective point of the cornea of ​​both eyes. In this embodiment, whether the patient's head is in the right position is determined based on whether the central reflective points of the cornea of ​​both eyes are in the same horizontal plane.

[0040] Furthermore, the recognition result of the central reflection point of the cornea of ​​both eyes is received in the angle calculation unit 132, and the inclination angle of the central reflection point of the cornea of ​​both eyes is calculated according to the coordinate information of the central reflection point of the cornea of ​​both eyes. The specific calculation method is to connect the central reflection points of the cornea of ​​two eyeballs according to the coordinate information of the central reflection point of the cornea of ​​both eyes, and then calculate the inclination angle of the connecting line relative to the horizontal line. This inclination angle is the inclination angle of the central reflection point of the cornea of ​​both eyes.

[0041] After obtaining the inclination angle of the central reflective point of the cornea of ​​both eyes, the comparison and judgment unit 133 judges whether the inclination angle of the central reflective point of the cornea of ​​both eyes meets the preset horizontal requirement, so as to judge whether the head of the patient in the current head alignment fixing device 110 is in the correct position. Specifically, if the inclination angle of the central reflective point of the cornea of ​​both eyes meets the preset horizontal requirement, it means that the line connecting the central reflective points of the cornea of ​​both eyes is in a horizontal state, which means that the head of the patient in the current head alignment fixing device 110 is in the correct position; if the inclination angle of the central reflective point of the cornea of ​​both eyes does not meet the preset horizontal requirement, it means that the line connecting the central reflective points of the cornea of ​​both eyes is not in a horizontal state, which means that the head of the patient in the current head alignment fixing device 110 is not in the correct position and needs to be adjusted.

[0042] In one embodiment, in combination Figure 2 It is noted that the control and adjustment device 130 further includes:

[0043] The angle adjustment unit 134 is connected to the comparison and judgment unit 133, and is used to use a control algorithm to calculate based on the tilt angle and the preset horizontal requirement to obtain a real-time adjustment angle when the patient's head is not in the correct position, and drive the rotating part of the head correction fixation device to rotate and adjust according to the real-time adjustment angle.

[0044] In this embodiment, the control algorithm includes but is not limited to: PID control algorithm, LQR control algorithm, adaptive control algorithm, predictive control algorithm, root locus method algorithm, frequency domain method algorithm, state feedback control algorithm, nonlinear control algorithm, neural network control algorithm, etc. In this embodiment, the preferred control algorithm adopts PID control algorithm, which calculates the real-time adjustment angle of the rotating component through the inclination angle of the central reflection point of the cornea of ​​both eyes, the preset horizontal requirement, and the current rotation angle of the rotating component, and drives the rotating component of the head correction fixing device to rotate and adjust according to the real-time adjustment angle to correct the patient's head. PID control refers to a controller obtained by linearly combining proportional, integral, and differential control. It is suitable for control objects where the system structure parameters cannot be fully mastered or where an accurate mathematical model cannot be obtained. It is most widely used in engineering practice and is characterized by simple structure, good stability, and reliable operation.

[0045] Furthermore, after the adjustment of the head alignment fixing device is completed, the image acquisition device re-captures the patient's eye image in real time, and further determines by controlling the adjustment device whether this adjustment makes the inclination angle of the central reflection point of the cornea of ​​both eyes meet the preset horizontal requirement. If so, it means that the patient's head is in the correct position and the next step of the patient's eye examination can be carried out. If not, the head alignment fixing device is continued to be adjusted until the requirements are met to achieve the patient's head correction.

[0046] In one embodiment, if Figures 3 to 5 , which is a schematic diagram of the structure of a head alignment fixing device for ophthalmic examination in an embodiment of the present invention. The head alignment fixing device comprises a bracket 1 and a rotating shaft 2 arranged on the bracket 1; the bracket 1 is driven to rotate by adjusting the rotation angle of the rotating shaft 2, so that the patient's head in the head alignment fixing device is aligned.

[0047] It should be noted that during the ophthalmic examination, the patient's head is fixed and positioned using a head fixation device to facilitate subsequent ophthalmic examinations. Figure 3 As shown, the head alignment fixing device is installed on the fixed workbench 8, and the head alignment fixing device includes a bracket 1, and the bracket 1 is connected to the fixed workbench 8, so as to be fixed on the fixed workbench 8. A rotating shaft 2 is provided on the bracket 1, and the rotating shaft 6 is controlled to rotate to drive the bracket 1 to swing left and right. The swing of the bracket 1 drives the entire head alignment fixing device to rotate, so that the crooked head of the patient located in the head alignment fixing device is aligned. After the head is aligned, the patient's eyes are correctly aligned with the position of the ophthalmic examination equipment for accurate examination. The head alignment fixing device can improve the accuracy and efficiency of ophthalmic examinations, and the patient's head can be adjusted and fixed by mechanical means to reduce the inspection error caused by head movement.

[0048] In one embodiment, if Figures 3 to 5 As shown, the head correction fixing device also includes a forehead rest 3, support rods 4 symmetrically arranged on both sides of the forehead rest 3, a mandibular rest 5, a lifting component 6 connected to the mandibular rest 5, and a telescopic component 7 arranged on the support rod 4; the support rod 4 and the lifting component 6 are respectively installed on the bracket 1; the forehead rest 3, the support rod 4 and the mandibular rest 5 together enclose a patient's head placement area; the lifting component 6 and the telescopic component 7 are adjusted to make the head placement area conform to the patient's head size.

[0049] It should be explained that the forehead support 3 is used to support the patient's forehead, and the mandibular support 5 is used to support the patient's mandible. The forehead support 3 and the mandibular support 5 are used together to ensure the stability of the patient's head during the examination. The support rods 4 symmetrically arranged on both sides of the forehead support 3 are fixedly mounted on the bracket 1. The support rods 4 play a role of connection and support. The forehead support 3 is installed in the middle position on the upper side of the support rods 4. The lifting component 6 is installed on the bracket 1, and is also connected to the mandibular support 5. The mandibular support 5 is driven up and down to adjust its height by lifting and lowering the lifting component 6. Two telescopic components 7 are symmetrically arranged on both sides of the forehead support 3 and the mandibular support 5 and fixed on the support rod 4. The telescopic component 7 can adopt a telescopic spring structure, or a rotating thread structure that can be freely extended and retracted, or a telescopic structure with multiple sections of sleeve connection, etc., which is not limited in this embodiment.

[0050] Furthermore, the forehead support 3, the support rod 4 and the mandibular support 5 together enclose a patient's head placement area, that is, an area where the patient's head is fixedly placed during the examination. By adjusting the lifting component 6 and the two telescopic components 7, the size of the head placement area can be adjusted to adapt to the size of different patients' heads.

[0051] In one embodiment, if Figures 3 to 5 As shown, the inner side of the telescopic component 7 is provided with a flexible fitting member 71. The flexible fitting member 71 is installed on the telescopic component 7. The flexible fitting member 71 can be an airbag cushion or sponge, etc., to fit the patient's face. In this embodiment, the flexible fitting member is preferably an airbag cushion, and the size of the airbag cushion can be controlled to fit different patient face sizes.

[0052] It should be understood that the telescopic component 7 in the present invention can adjust the size of the head placement area by adjusting the distance of the telescopic component into the inner side of the support rod. However, if the patient's head is too small, then only adjusting the distance may cause the area size not to match the patient's head size. In this case, the inflation amount of the flexible fitting part 71 on the telescopic component 7 can be adjusted at the same time to reduce the size of the head placement area so as to fit the head size of the patient with a small head.

[0053] like Figures 3 to 5As shown, the head alignment fixing device is connected to the control and adjustment device 130, and the connection method can be a wired connection or a wireless connection. In this embodiment, the head alignment fixing device and the control and adjustment device 130 are connected by a wired connection. The control and adjustment device 130 is a desktop computer or a laptop computer. After receiving the image data and processing it, the computer sends a control signal to the head alignment fixing device for adjustment to make the head aligned.

[0054] It should be noted that the head alignment fixation device designed in this embodiment can not only align the patient's head, but also be adjusted according to the patient's head size to ensure comfort and accuracy of the examination. By adjusting the rotating component, the patient's head alignment can be controlled, and by adjusting the telescopic component, personalized fixation can be provided for different patients, reducing discomfort and examination errors caused by the patient's head being out of alignment or the head size not matching, thereby improving the quality of ophthalmic examinations and the patient's experience.

[0055] It should be emphasized that the present invention continuously captures and collects eyeball images through an image acquisition device and feeds back to a control and adjustment device, thereby realizing automatic identification of the central reflective points of the patient's corneas, and automatically adjusting the position of the patient's head by comparing the position of the line connecting the central reflective points of the corneas of the two eyes with the horizontal line, ensuring that the central reflective points of the corneas of the two eyes are on the same horizontal line. The present invention automatically adjusts the position of the head in the head correction device, and fixes the patient's head so that it does not move during the examination process, thereby ensuring that the head remains stable during the ophthalmic examination, eliminating the need for the examiner to manually adjust the head position, significantly reducing the examiner's working time, and improving the accuracy and efficiency of the ophthalmic examination.
