[0047] The terms "first", "second" in the description, claims and drawings of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. For the methods disclosed in the embodiments of the present application or the methods shown in the flowcharts, including one or more steps for implementing the methods, without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be deleted.
[0048] The embodiments of the present application provide a fundus photographing control method, device and fundus camera, which can reduce accidental injuries, have high safety, and at the same time have the effects of tracing patient data and protecting patient privacy.
[0049] Please refer to Figure 1 and Figure 2 , the fundus photographing control method provided by the present application can be applied to a fundus camera. The fundus camera can be a tabletop fundus camera or a handheld fundus camera. In the present application, a handheld fundus camera is taken as an example. The handheld fundus camera is easy to carry, and has a networking function and data processing ability, which is beneficial to providing one-stop health management for families, enterprises, primary medical institutions, etc., and is also applicable to remote medical scenarios such as inside and outside hospitals, remote rural areas, and community care.
[0050] Please refer to Figure 1 and Figure 3 , in this embodiment, the housing 10 of the fundus camera has a handheld end 11 and a photographing end 12. A control module 13 and a communication module 14 are built in the housing 10. A display panel 15 and a key module 16 are arranged at the handheld end 11, and a photographing module 17 is arranged at the photographing end 12. The communication module 14, the display panel 15, the key module 16 and the photographing module 17 are all electrically connected to the control module 13. Among them, the photographing module 17 is used to photograph images, the display panel 15 is used to display the photographed images or data information such as specified device states, the key module 16 is for medical staff to touch and operate, the communication module 14 is used to establish wireless communication between the control module 13 and external devices, and the control module 13 is used to process various types of data.
[0051] In this embodiment, the fundus camera accesses the cloud 20 through the communication module 14, and various types of data collected by the fundus camera can be uploaded to the cloud 20. The management personnel can access the cloud 20 through the back-end management system to process and verify various types of data uploaded by the fundus camera. Relevant personnel can access the cloud 20 through the intelligent terminal 30 (such as a computer, mobile phone, etc.) to obtain the shooting results uploaded by the fundus camera.
[0052] In this embodiment, the fundus camera has a first state and a second state. When the fundus camera is in the first state, the usage permission of the fundus camera is locked, and the fundus camera is prohibited from taking fundus photos of patients; when the fundus camera is in the second state, the fundus camera is allowed to take fundus photos of patients. The initial state after the fundus camera is powered on is the first state. At this time, medical staff need to unlock the fundus camera to switch the fundus camera from the first state to the second state.
[0053] In an application scenario of telemedicine, before medical staff use the fundus camera to take fundus photos of a patient at a first location, they first switch the fundus camera from the first state to the second state, and then take the photo. The fundus image taken by the fundus camera will be uploaded to the cloud 20. Doctors and experts located at a second location can download the fundus image through the intelligent terminal 30 and preliminarily observe various medical signs from the fundus image.
[0054] Please refer to Figure 1 and Figure 4 , the fundus photography control method provided by the embodiment of the present application can be applied to a fundus camera. The fundus photography control method includes:
[0055] S401. Obtain a first recognition image.
[0056] Among them, the first recognition image is an image obtained by the fundus camera photographing a first recognition object within the shooting range. The first recognition object corresponds to a first person.
[0057] In this embodiment, the first person is the medical staff operating the fundus camera and has the professional level of operating the fundus camera. It can be understood that the first person has a corresponding medical staff identity. The first recognition object is an object that can prove the medical staff identity of the first person, such as the work permit of the medical staff, etc.
[0058] In one implementation manner, the fundus camera itself has an image recognition function and can automatically recognize and photograph the first recognition object within the shooting range.
[0059] Step S401 may include: when the fundus camera recognizes a first recognition object within the shooting range, obtaining a first recognition image. When the fundus camera is in the first state and the first recognition object is within the shooting range of the fundus camera, obtain the first recognition image.
[0060] In one implementation, step S401 may further include: in response to a first shooting instruction, obtaining a first recognition image. Wherein, the first shooting instruction is a control instruction triggered according to the operation of a first person. For example, when the first recognition object is within the shooting range of the fundus camera, the first person triggers the first shooting instruction by touching the key module 16 of the fundus camera, and the fundus camera obtains the first recognition image in response to the first shooting instruction.
[0061] S402. Perform medical staff identity verification on the first person according to the first recognition image.
[0062] Wherein, the personal certificate captured in the first recognition image is recognized and processed to determine the medical staff identity of the first person, so as to perform medical staff identity verification on the first person.
[0063] S403. Determine whether the medical staff identity verification of the first person is successful. If so, execute step S404.
[0064] S404. Control the fundus camera to switch from the first state to the second state.
[0065] Wherein, the first state is the automatically reset state after the fundus camera is powered on. When the fundus camera is in the first state, it is not allowed for the fundus camera to obtain the patient information of a second person. When the fundus camera is in the second state, it is allowed for the fundus camera to obtain the patient information of the second person.
[0066] In this embodiment, the second person refers to a patient who requires the first person to operate the fundus camera for fundus photography. The patient information includes patient data, such as the patient's name, etc., and the patient's identity can be recorded through the patient information.
[0067] It can be understood that when the fundus camera is in the first state, at this time the fundus camera does not have the usage permission, and the task person cannot directly perform fundus photography on the second person through the fundus camera, and the fundus images captured by the fundus camera cannot be uploaded to the cloud 20.
[0068] When the medical staff identity verification of the first person is successful, the fundus camera switches from the first state to the second state. At this time, the first person has the usage permission relative to the fundus camera. The fundus camera switches from the first state to the second state, allowing the fundus camera to perform fundus photography on the second person, and allowing the fundus images captured by the fundus camera to be uploaded to the cloud 20.
[0069] The default initial state of the fundus camera provided by this application after power-on is the first state. In the first state, the fundus camera prohibits fundus photography of the second person. When fundus photography is required, first, the fundus camera obtains the first identification image of the first person, and then verifies the medical staff identity of the first person based on the first identification image. Only after successful verification, the fundus camera switches from the first state to the second state, allowing the fundus camera to perform fundus photography on the second person. In this way, fundus photography of the second person can be allowed only after determining the medical staff identity of the first person, avoiding non-professional personnel from operating the fundus camera, thereby reducing accidental injuries to patients and having higher safety.
[0070] In an embodiment of the present application, in step S403, if it is determined that the verification of the medical staff identity of the first person fails, step S405 is executed.
[0071] S405. Control the fundus camera to output a verification failure message.
[0072] Among them, the verification failure message is used to indicate that the verification of the medical staff identity has not been completed.
[0073] When the verification of the medical staff identity of the first person fails, the first person does not have the usage permission relative to the fundus camera, and the fundus camera remains in the first state.
[0074] For example, within a preset time, if the fundus camera does not recognize the first identification object within the shooting range, a verification failure message is output. That is, when the fundus camera is in the first state and the first identification object is outside the shooting range of the fundus camera, control the fundus camera to output a verification failure message.
[0075] In this embodiment, after the fundus camera outputs a verification failure message, a verification failure page is displayed through the display panel 15 to prompt the medical staff to re-verify the medical staff identity.
[0076] In a remote medical application scenario of the present application, the method for a medical staff to use a fundus camera to perform fundus photography on a patient includes:
[0077] First, the medical staff starts the fundus camera, and the fundus camera is in the first state. At this time, the display panel 15 of the fundus camera can prompt the medical staff to verify the medical staff identity.
[0078] Then, the medical staff can operate the key module 16 of the fundus camera to trigger the medical staff identity verification function and take a personal certificate through the fundus camera. The fundus camera obtains the first identification image to verify the medical staff identity of the medical staff.
[0079] If the healthcare staff authentication is successful, the display panel 15 of the fundus camera can display a successful authentication page, the fundus camera switches to the second state, and it is determined that the healthcare staff is the current operator, allowing the healthcare staff to operate the fundus camera to take fundus photos of the patient. The shooting results of the fundus camera will be automatically uploaded to the cloud 20 for archiving the test results and for doctors and experts to view.
[0080] If the healthcare staff authentication fails, the display panel 15 of the fundus camera displays a failed authentication page, and the fundus camera remains in the first state.
[0081] In an embodiment of the present application, before operating the fundus camera, the healthcare staff first needs to enter personal data in the cloud 20 and apply for registering a personal account. Among them, when the healthcare staff successfully registers a personal account, the cloud 20 will generate a unique identification code belonging to the personal account of the healthcare staff. The identification code has information associated with the healthcare staff, and this information includes but is not limited to healthcare staff information and an identity token (Token). Among them, the identity token is used to indicate the permission to operate the fundus camera, and the healthcare staff information includes personal data such as the name and work number of the healthcare staff.
[0082] Please refer to Figure 3 and Figure 5 , in this embodiment, the first identification object is a work certificate printed with the identification code, and each healthcare staff has a corresponding identification code. The identification code can be a matrix two-dimensional code (QR Code).
[0083] Step S401 specifically includes: photographing the first identification object of the first person to obtain a first identification image. The first identification image is photographed with the identification code of the first identification object.
[0084] Step S402 specifically includes: parsing the identification code in the first identification image to obtain the identity token of the first person.
[0085] Step S403 specifically includes: determining whether the identity token of the first person is successfully obtained. If so, execute step S404; if not, execute step S405.
[0086] It can be understood that if the identification code is successfully parsed, the identity token carried by the identification code can be obtained, and this identity token is regarded as the identity token of the first person. Therefore, it can be determined that the healthcare identity authentication of the first person is successful, that is, the first person has the identity permission to operate the fundus camera. On the contrary, if the identification code parsing fails, the identity token of the first person cannot be obtained, and it is determined that the healthcare identity authentication of the first person fails.
[0087] Specifically, the implementation method of parsing the first identification image is:
[0088] The fundus camera converts the first recognition image into a parsed file in the format of a Base64 string and uploads it to the cloud 20. The back-end management system obtains the parsed file from the cloud 20 and calls the QR code parsing suite to parse the parsed file.
[0089] If the back-end management system successfully parses the file, the corresponding identity token and medical staff identity can be obtained. The back-end management system sends the identity token and medical staff identity to the cloud 20, and the cloud 20 sends them to the fundus camera, and the fundus camera confirms that the verification of the medical staff identity is successful.
[0090] Conversely, if the back-end management system fails to parse the file, the back-end management system sends the parsing failure information to the cloud 20, and the cloud 20 sends it to the fundus camera, and the fundus camera confirms that the verification of the medical staff identity fails.
[0091] In this embodiment, the reasons for the failure of the back-end management system to parse the file may be: there is no corresponding identity token for the captured recognition code, or the first recognition image does not capture a clear recognition code.
[0092] It can be understood that in step S401, if the first recognition image does not capture the first recognition object of the first person, there is no recognizable code in the first recognition image, which will cause the back-end management system to fail to parse the recognition code, and then step S405 is executed, and the fundus camera prompts that the verification of the medical staff identity fails.
[0093] In an embodiment of the present application, step S404 further includes: displaying the corresponding medical staff information through the display panel 15.
[0094] Among them, after the first person operates the fundus camera to verify the medical staff identity and the verification is successful, the display panel 15 of the fundus camera will display the medical staff information of the first person. The first person can check whether the current medical staff information is their own data information. If it is found that the data is incorrect, an error report can be made and the medical staff identity verification can be performed again to prevent data confusion.
[0095] In an embodiment of the present application, the fundus camera also has a third state. Among them, when the fundus camera is in the first state or the second state, the fundus camera prohibits taking fundus images of patients; when the fundus camera is in the third state, the fundus camera allows taking fundus images of patients.
[0096] It can be understood that when the fundus camera is in the second state, although the fundus camera already has the usage permission for medical staff, there is no patient data recorded in the fundus camera. It is necessary for the medical staff to enter the patient data into the fundus camera to switch the fundus camera from the second state to the third state.
[0097] Please refer to Figure 3 and Figure 6, in this embodiment, after step S404, that is, when the fundus camera is in the second state, the fundus photographing method further includes:
[0098] S501. Obtain a second recognition image.
[0099] Wherein, the second recognition image is an image obtained by the fundus camera photographing a second recognition object located within the photographing range. The second recognition object corresponds to a second person.
[0100] In one implementation manner, the fundus camera itself has an image recognition function and can automatically recognize and photograph the second recognition object within the photographing range.
[0101] Step S501 may include: when the fundus camera recognizes the second recognition object within the photographing range, obtain the second recognition image. That is, when the fundus camera is in the second state and the second recognition object is within the photographing range of the fundus camera, obtain the second recognition image.
[0102] In one implementation manner, step S501 may further include: in response to a second photographing instruction, obtain the second recognition image. Wherein, the second photographing instruction is a control instruction triggered according to the operation of the first person. For example, when the second recognition object is within the photographing range of the fundus camera, the second person triggers the second photographing instruction by touching the key module 16 of the fundus camera, and the fundus camera obtains the second recognition image in response to the second photographing instruction.
[0103] In this embodiment, the second recognition object is an object recorded with the patient information of the second person by the patient, such as the patient's ID card, social security card, medical record card, etc.
[0104] S502. Obtain the patient information of the second person according to the second recognition image.
[0105] Wherein, the second recognition object photographed in the second recognition image is recognized and processed to determine the patient identity of the second person, and the corresponding patient data is extracted to obtain the patient information.
[0106] S503. Judge whether the acquisition of the patient information of the second person is successful. If so, execute step S504; if not, execute step S506.
[0107] S504. Control the fundus camera to switch from the second state to the third state.
[0108] Wherein, in response to the successful acquisition of the patient information of the second person, at this time the fundus camera successfully enters the patient data, then the fundus camera switches from the second state to the third state, and the fundus camera is allowed to photograph the fundus of the second person.
[0109] S505. In response to a fundus photographing instruction, photograph the fundus of the second person to obtain fundus photographing information.
[0110] The fundus photographing instruction is a control instruction triggered according to the operation of the first person.
[0111] The fundus photographing information is the photographing result of the fundus camera. The fundus photographing information includes a fundus image obtained by the fundus camera photographing the fundus of the second person.
[0112] S506. Control the fundus camera to output a failure message for entry.
[0113] The failure message for entry is used to indicate that the patient information has not been successfully obtained. At this time, the fundus camera has not entered the patient data, and the fundus camera remains in the second state.
[0114] For example, within a preset time, if the fundus camera does not recognize the second recognition object within the photographing range, it outputs a failure message for entry. That is, when the fundus camera is in the second state and the second recognition object is outside the photographing range of the fundus camera, control the fundus camera to output a failure message for entry.
[0115] In this embodiment, after the fundus camera outputs a failure message for entry, a failure page for entry is displayed through the display panel 15 to prompt the medical staff to re-enter the patient data.
[0116] In this embodiment, when the fundus camera is in the first state, the first person does not have the permission to use the fundus camera. At this time, the first person cannot enter the patient information of the second person through the fundus camera, nor can they use the fundus camera to photograph the fundus of the second person.
[0117] When the fundus camera is in the second state, the first person has obtained the permission to use the fundus camera. At this time, if the fundus camera is in the second state, it means that the fundus camera has not obtained the patient information, indicating that the fundus camera has not determined the patient object to be photographed and has not completed the preparation work before fundus photographing. The first person still cannot use the fundus camera to photograph the fundus of the second person. If the fundus camera is in the waiting success state, it means that the fundus camera has obtained the patient information and determined the patient object to be photographed, and the first person can use the fundus camera to photograph the fundus of the second person.
[0118] It can be understood that by obtaining the patient information of the second person, the patient data of the second person is entered into the fundus camera before the formal photographing, preventing the fundus camera from being used for purposes unrelated to fundus photographing, so as to facilitate the use management of the fundus camera.
[0119] Please refer to Figure 3 and Figure 7, in an embodiment of the present application, the second identification object is the patient's ID card, which records the name and ID number of the ID card. Correspondingly, the patient's personal information includes the patient's name and ID number.
[0120] Step S501 specifically includes: photographing the second identification object of the second person to obtain the second identification image of the second person.
[0121] Step S502 specifically includes: performing character recognition on the second identification object in the second identification image to obtain the patient's personal information of the second person.
[0122] Among them, the fundus camera converts the second identification image into an identification file in the format of a Base64 string and uploads it to the cloud 20. The backend management system obtains the identification file from the cloud 20 and performs character recognition on the identification file through an optical character recognition (OCR) algorithm.
[0123] Step S503 specifically includes: determining whether the character recognition of the second identification image is successful. If so, step S504 is executed; if not, step S506 is executed.
[0124] If the character recognition of the backend management system is successful, the name and ID number of the second person's ID card can be obtained, and the corresponding patient's personal information can be obtained. The backend management system sends the patient's personal information to the cloud 20, and the cloud 20 sends it to the fundus camera, and the fundus camera confirms that the patient data entry is successful.
[0125] On the contrary, if the character recognition of the backend management system fails, the backend management system sends the recognition failure information to the cloud 20, and the cloud 20 sends it to the fundus camera. The fundus camera confirms that the patient data entry fails, and it is not allowed to perform fundus photography on the second person.
[0126] In this embodiment, the reason for the failure of the character recognition of the backend management system may be that the second identification object is not clearly photographed in the second identification image.
[0127] It can be understood that in step S501, if the second identification object of the second person is not photographed in the second identification image, there will be no patient data that can be recognized by characters in the second identification image, which will cause the character recognition of the backend management system to fail. Then step S506 is executed, and the fundus camera prompts that the acquisition of the patient's personal information fails.
[0128] In an embodiment of the present application, step S503 further includes: displaying the corresponding patient's personal information through the display panel 15.
[0129] After the first person operates the fundus camera to enter the patient data and the entry is successful, the display panel 15 of the fundus camera will display the patient information of the second person.

That is, when the fundus camera is in the third state, in response to a fundus photographing instruction, photograph the fundus of the second person to obtain a fundus image.
[0133] S702. Bind the fundus image of the second person and the corresponding associated information to obtain fundus photographing information.
[0134] Among them, the associated information is data information associated with this fundus photographing, and is used to record personnel data, photographing data, etc. other than the photographed image.
[0135] After the fundus camera obtains the fundus photographing information, it uploads the fundus photographing information to the cloud 20 as a photographing result for archiving. Remote doctor experts can view the fundus image photographed in the fundus photographing information and the bound associated information to more comprehensively understand the patient's condition.
[0136] Please refer to Figure 3 and Figure 8 In one implementation manner, when the fundus camera is in the third state, the first person can select the corresponding photographing part through the key module 16 of the fundus camera, and then start photographing. Among them, after the first person selects the corresponding photographing part, the display panel 15 of the fundus camera will display the corresponding photographed part for the first person to verify whether there is a selection error.
[0137] In this embodiment, when the fundus camera is in the third state, the fundus photographing instruction carries photographing part information, and the photographing part information is used to indicate the photographing part for photographing the fundus of the second person (such as the left eyeball, the right eyeball, etc.).
[0138] Specifically, the associated information can be photographing information, and the photographing information includes the photographing time information of the fundus image and the photographing part information of the fundus image.
[0139] Step S702 specifically includes: binding the fundus image of the second person and the corresponding shooting information to obtain fundus shooting information.

[0141] Please refer to Figure 3 and Figure 9 , in one implementation, the associated information can be medical staff information.
[0142] Step S702 specifically includes: binding the fundus image of the second person and the medical staff information of the first person to obtain fundus shooting information.
[0143] It can be understood that the fundus image and the medical staff information are bound and archived in the cloud 20, which is convenient for tracing the medical staff who took the fundus image. For example, when a remote doctor or expert views the fundus image, they can contact the corresponding medical staff to inquire about the on-site situation.
[0144] Please refer to Figure 3 and Figure 10 , in one implementation, the associated information can be patient information.
[0145] Step S702 specifically includes: binding the fundus image of the second person and the corresponding patient information to obtain fundus shooting information.
[0146] It can be understood that the fundus image and the patient information are bound and archived in the cloud 20, and the fundus image is automatically classified as the fundus examination result of the corresponding patient, saving the time of manual classification.
[0147] Please refer to Figure 3 and Figure 11 , in one implementation, the fundus camera has the function of manually deleting fundus images. After the first person operates the fundus camera to obtain the fundus image, they can view the currently taken fundus image of the second person through the display panel 15 of the fundus camera. If the first person finds that the shooting effect of the fundus image is not good, they can select to delete the specified fundus image through the operation key module 16 and take the fundus shot again.
[0148] The associated information includes medical staff information and the number of shootings. The number of shootings is the number of times the first person operates the fundus camera to take the fundus shot of the second person this time.
[0149] Step S702 specifically includes: binding the medical staff information of the first person, the corresponding number of shootings and the fundus image of the second person to obtain fundus shooting information.
[0150] It can be understood that the number of shootings can evaluate the operation proficiency and operation level of the first person, so as to facilitate the management of the usage permission of the fundus camera. For example, when the average value of the number of shootings in the most recent N (N is greater than or equal to 1) fundus shootings by medical staff is greater than the preset threshold, the usage permission of the fundus camera for the medical staff will be cancelled, and the identity token of the medical staff will be deleted.
[0151] Please refer to Figure 3 and Figure 12 , in an implementation manner, the associated information includes shooting information, patient information, medical staff information, and the number of shootings.
[0152] Step S702 specifically includes: binding the shooting information, patient information, medical staff information, and the number of shootings with the fundus image to obtain fundus shooting information.
[0153] It can be understood that the fundus shooting information carries the shooting time, shooting location, patient data of the second person, personal data of the first person, and the number of camera shootings in this fundus shooting, expanding various types of information of the fundus shooting, so as to facilitate data management and traceability of the fundus shooting.
[0154] Please refer to Figure 3 and Figure 13 , in an embodiment of the present application, after step S404, that is, when the fundus camera is in the second state, the fundus shooting method further includes:

At the same time, the patient information associated with the medical staff information and the patient information will also be cleared, and the fundus camera will switch from the third state to the second state.
[0158] It can be understood that after the first person clears their own data, the next medical staff using the fundus camera can re-perform the medical staff identity verification to obtain the operation permission of the fundus camera.
[0159] In this way, after the medical staff finishes taking fundus photographs of the patient, the local storage of the fundus camera can delete the medical staff information of the medical staff, the patient information of the patient, and the taken fundus photograph information. The deleted data information can only be viewed from the cloud 20, thereby preventing the leakage of patient data and protecting personal privacy.
[0160] In an embodiment of the present application, the fundus photographing method further includes:
[0161] When the fundus camera is in the second state and the first identification object is within the photographing range of the fundus camera, an authority clearing instruction is output, and step S401 is executed.
[0162] Wherein, when the fundus camera has completed medical staff identity verification and at the same time the fundus camera identifies the first identification object within the photographing range, it is considered that the medical staff identity verification needs to be re-performed. Then, an authority clearing instruction is output to control the fundus camera to clear the currently taken fundus photograph data and reset it to the first state.
[0163] In this way, after the previous medical staff finishes taking fundus photographs of the previous patient and before the next medical staff takes fundus photographs of the next patient, the next medical staff needs to re-perform medical staff identity verification, that is, photograph the work permit of the next medical staff through the fundus camera. At this time, the local storage of the fundus camera automatically deletes the medical staff information of the previous medical staff, the patient information of the previous patient, and the taken fundus photograph information. The deleted data information can only be viewed from the cloud 20, thereby preventing the leakage of patient data and protecting personal privacy.

[0171] After the first person has used the fundus camera to complete the fundus photographing of the current patient, the fundus camera will clear the current patient information and associated fundus photographing information, and the fundus camera will switch from the third state to the second state.
[0172] In this way, after the second person has completed the fundus photographing, the first person can delete the current patient information and associated fundus photographing information. The deleted data information can only be viewed from the cloud 20, thereby preventing the leakage of patient data and protecting personal privacy.
[0173] In an embodiment of the present application, the fundus photographing method further includes:
[0174] When the fundus camera is in the third state and the second identification object is within the shooting range of the fundus camera, output a personnel clearing instruction and execute step S501.
[0175] Among them, when the fundus camera has completed the entry of patient data and at the same time the fundus camera recognizes the second identification object within the shooting range, it is considered that the patient data needs to be re-entered, then output a personnel clearing instruction, control the fundus camera to clear the current patient's data, and reset it to the second state.
[0176] In this way, after the previous patient has completed the fundus photographing and before the next patient conducts the fundus photographing, the first person can directly re-photograph the second identification object of the next patient. At this time, the fundus camera will automatically delete the patient information of the previous patient and the fundus photographing information taken locally. The deleted data information can only be viewed from the cloud 20, thereby preventing the leakage of patient data and protecting personal privacy. After that, the patient information of the next patient can be re-entered into the fundus camera. For details, see step S501 and related descriptions.
