Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a fully self-service fundus camera and a method for setting a photographing mode. Background Art

[0002] In order to realize the collection of the user's fundus image, in the invention patent application CN202310955386.0 "Image shooting method based on fundus camera, fundus camera, device and medium", the fundus image of the user is accurately collected through a fundus camera, thereby improving the efficiency and accuracy of the recognition and processing of fundus lesions.

[0003] However, in the existing technical solutions, fundus cameras generally include multiple modes such as color acquisition, monochrome acquisition and video acquisition, and the settings of existing photo modes are often based on the user's own settings. However, users often lack professional medical knowledge. Therefore, the fundus data obtained by the photo mode they choose may not be able to accurately evaluate the actual fundus pathological status.

[0004] In response to the above technical problems, the present invention determines whether the photographing mode selected by the user meets the requirements by analyzing the user's historical fundus lesion data and the fundus lesion data of the user's selected photographing mode, and makes targeted recommendations on photographing modes to improve the accuracy and reliability of obtaining fundus lesion data.

[0005] Specifically, the present application provides a fully self-service fundus camera and a method for setting a photographing mode. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, a method for setting a photographing mode of a fully self-service fundus camera is provided.

[0008] A method for setting a photographing mode of a fully self-service fundus camera, specifically comprising:

[0009] S1 determines the user's fundus camera usage record using the user's identity recognition result, determines the distribution of the user's fundus camera usage time based on the usage record, and determines that the user's fundus camera usage proficiency meets the requirements using the distribution of the usage time, then proceeds to the next step;

[0013] A further technical solution is that the identity recognition result of the user is determined based on the reading result of the user's account or the facial recognition result.

[0014] A further technical solution is that the usage record of the fundus camera includes the number of usage periods of the fundus camera and the times corresponding to different usage periods.

[0015] A further technical solution is to regard the usage data of the fundus camera of the user within a unit time as a same usage period.

[0016] A further technical solution is that the method for determining the user's recommended photographing mode is:

[0017] The use period of the photographing mode is used as the matching use period, and the photographing pass rates of different matching use periods are determined according to the image pass rates and the number of pass images in different matching use periods;

[0018] Determine the shooting timeliness of different matching use periods based on the historical shooting times of different matching use periods;

[0019] The comprehensive reliability coefficient of the photographing mode is determined according to the photographing qualification rate and the photographing timeliness of different matching use time periods, and the recommended photographing mode is determined using the comprehensive reliability coefficient.

[0020] A further technical solution is that when the image clarity of the historical fundus image meets the requirement, the historical fundus image is determined to be a qualified image.

[0021] A further technical solution is to use the comprehensive reliability coefficient to determine the recommended photographing mode, specifically including:

[0022] The shooting mode with the largest comprehensive reliability coefficient is used as the recommended shooting mode.

[0023] A further technical solution is to determine whether it is necessary to switch the photographing mode, which specifically includes:

[0024] Acquire multiple fundus images using a preset number of fundus images, determine image clarity of the fundus images based on analysis results of the fundus images, determine qualified fundus images among the fundus images using the image clarity, and determine image quality of the fundus images according to the number of qualified fundus images and the image clarity of different qualified fundus images;

[0025] Determine unqualified fundus images caused by eye position change or facial position change of the user through the analysis result of the fundus image, and use them as abnormal change images, and determine the abnormal position change value of the user by using the number of abnormal change images;

[0026] The matching coefficient of the current photographing mode is determined according to the image quality of the fundus image and the abnormal value of the position change of the user, and the matching coefficient is used to determine whether the photographing mode needs to be switched.

[0027] A further technical solution is that when the matching coefficient is less than a preset matching threshold, it is determined that the photographing mode needs to be switched.

Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0046] Example 1

[0047] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a method for setting a photographing mode of a fully self-service fundus camera is provided, which specifically includes:

[0048] S1 determines the user's fundus camera usage record using the user's identity recognition result, determines the distribution of the user's fundus camera usage time based on the usage record, and determines that the user's fundus camera usage proficiency meets the requirements using the distribution of the usage time, then proceeds to the next step;

[0049] Furthermore, the identity recognition result of the user is determined based on the reading result of the user's account or the facial recognition result.

[0050] It can be understood that the usage record of the fundus camera includes the number of usage periods of the fundus camera and the times corresponding to different usage periods.

[0051] It should be noted that the usage data of the fundus camera of the user within a unit time period is regarded as the same usage period.

[0052] Specifically, it should be noted that Figure 2 As shown, determining that the user's proficiency in using the fundus camera meets the requirements specifically includes:

[0053] Determine the number of usage periods in different divided time periods by using the distribution of the usage moments, and determine the proficiency influence values ​​of the different divided time periods by using the number of usage periods in the different divided time periods;

[0054] Determine weight values ​​of different divided time periods based on the time lengths from the current moment to different divided time periods, and determine the user's proficiency in using the fundus camera in combination with the proficiency influence values ​​of the different divided time periods;

[0055] Whether the user's proficiency in using the fundus camera meets the requirement is determined based on the user's proficiency in using the fundus camera.

[0056] Further, when the user's proficiency in using the fundus camera is less than a preset proficiency, it is determined that the user's proficiency in using the fundus camera meets the requirement.

[0057] It should also be noted that determining that the user's proficiency in using the fundus camera meets the requirements specifically includes:

[0058] Determine the number of usage periods of the user within a recent preset time period using the time corresponding to the usage period of the fundus camera by the user, and use it as the adjacent usage period;

[0059] Whether the user's proficiency in using the fundus camera meets the requirement is determined according to the number of the approaching use time periods.

[0060] It can be understood that when the number of the approaching use time periods is less than the number of preset time periods, it is determined that the user's proficiency in using the fundus camera meets the requirement.

[0061] In another embodiment, determining that the user's proficiency in using the fundus camera meets the requirement specifically includes:

[0062] S11 obtains the number of time periods during which the user uses the fundus camera, and determines whether the number of time periods during which the user uses the fundus camera is less than a preset number of time periods. If so, it is determined that the user's proficiency in using the fundus camera does not meet the requirement. If not, proceed to the next step.

[0063] S12 determines whether the number of time periods during which the user uses the fundus camera is within a preset time period number interval, if so, proceeds to the next step, if not, proceeds to step S15;

[0064] S13 determines the number of usage periods of the user in the most recent preset time period by using the time corresponding to the usage period of the fundus camera of the user, and uses it as the adjacent usage period, and determines whether the number of adjacent usage periods is less than the preset number of adjacent periods. If so, it is determined that the user's proficiency in using the fundus camera does not meet the requirement, and if not, proceeds to the next step;

[0065] S14: determining weight values ​​of different use periods by using the time corresponding to the use period of the fundus camera by the user, and determining whether the user's proficiency in using the fundus camera does not meet the requirement based on the sum of the weight values ​​of the different use periods; if so, determining that the user's proficiency in using the fundus camera does not meet the requirement; if not, proceeding to the next step;

[0068] It is understandable that when the user's proficiency in using the fundus camera does not meet the requirements, the user's fundus image is acquired by taking photos using video acquisition.

[0069] S2: taking the unqualified fundus image caused by the eye position change or face position change of the user as the abnormal movement image, obtaining the abnormal movement image of the user during the use period of the fundus camera, and determining that the position change of the user meets the requirements by combining the user change types corresponding to different abnormal movement images, and then proceeding to the next step;

[0070] Furthermore, the user change type includes eye position change and facial position change, and the specific user change type is determined according to the image analysis result of the user's abnormal movement image.

[0071] It should be noted that determining that the location change of the user can meet the requirements specifically includes:

[0072] The usage period with abnormal movement images is regarded as the abnormal movement usage period, and whether the location change of the user can meet the requirements is determined by the proportion of the abnormal movement usage period.

[0073] It is also understandable that when the position change of the user does not meet the requirements, the fundus image of the user is acquired by taking a photo through video acquisition.

[0074] It should be further explained that when the proportion of the number of abnormal mobile usage time periods is greater than the preset proportion, it is determined that the location change of the user does not meet the requirements.

[0075] In another embodiment, Figure 3 As shown, determining that the location change of the user can meet the requirements specifically includes:

[0076] Determine the number of abnormal movement images under different user change types according to the user change type corresponding to the abnormal movement images in the use period of the fundus camera by the user, and determine the abnormal movement weight values ​​of different use periods according to the number of abnormal movement images under different user change types;

[0077] The abnormal movement weight value is used to determine the abnormal movement usage period in the usage period, and according to the number of the abnormal movement usage period, it is determined whether the location change of the user can meet the requirement.

[0078] In another possible embodiment, determining whether the location change of the user can meet the requirement specifically includes:

[0079] Obtaining the number of abnormal movement images of the user, and determining whether the number of abnormal movement images of the user meets the requirement, if so, proceeding to the next step, if not, determining that the position change of the user cannot meet the requirement;

[0080] The usage period with abnormal movement images is regarded as the abnormal movement usage period, and whether the number of the abnormal movement usage period of the user meets the requirement is determined, if so, proceeding to the next step, if not, determining that the position change of the user cannot meet the requirement;

[0081] Determine the number of abnormal movement images under different user change types according to the user change type corresponding to the abnormal movement images in the use period of the fundus camera, and determine the abnormal movement weight values ​​of different use periods by using the number of abnormal movement images under different user change types, and use the abnormal movement weight values ​​to determine whether there is an abnormal movement use period in the use period, if yes, proceed to the next step, if not, determine whether the position change of the user can meet the requirements;

[0082] Determine whether the user's location change can meet the requirement according to the number of abnormal mobile usage periods, if so, proceed to the next step, if not, determine that the user's location change cannot meet the requirement;

[0083] The abnormal movement weight values ​​of different abnormal usage periods are obtained, and the abnormal values ​​of the user's location changes are evaluated in combination with the moments corresponding to the different abnormal usage periods, and the abnormal values ​​of the location changes are used to determine whether the user's location changes can meet the requirements.

[0084] S3 obtains historical fundus images of the user using different photographing modes, determines the image qualification rate of the historical fundus images, and determines the recommended photographing mode of the user based on the historical photographing times of the different photographing modes;

[0085] It should be noted that if Figure 4 As shown, the method for determining the recommended photographing mode of the user is:

[0086] The use period of the photographing mode is used as the matching use period, and the photographing pass rates of different matching use periods are determined according to the image pass rates and the number of pass images in different matching use periods;

[0087] Determine the shooting timeliness of different matching use periods based on the historical shooting times of different matching use periods;

[0088] The comprehensive reliability coefficient of the photographing mode is determined according to the photographing qualification rate and the photographing timeliness of different matching use time periods, and the recommended photographing mode is determined using the comprehensive reliability coefficient.

[0089] Further, when the image clarity of the historical fundus image meets the requirement, the historical fundus image is determined to be a qualified image.

[0090] It should be further explained that the determination of the recommended photographing mode by using the comprehensive reliability coefficient specifically includes:

[0091] The shooting mode with the largest comprehensive reliability coefficient is used as the recommended shooting mode.

[0092] In another possible embodiment, the method for determining the user's recommended photographing mode is:

[0093] S11 uses the usage period of the photographing mode as the matching usage period, and determines whether the number of the matching usage period is greater than the preset matching period number. If so, proceed to the next step; if not, proceed to step S15;

[0094] S12 uses the historical fundus image of the photographing mode as the matching fundus image, and determines whether the qualified rate of the matching fundus image is less than the preset qualified rate. If so, it is determined that the photographing mode does not belong to the recommended photographing mode. If not, proceed to the next step;

[0095] S13 performs matching use periods in which the image pass rates do not meet the requirements according to the image pass rates of different matching use periods, and determines whether the number of matching use periods in which the image pass rates do not meet the requirements meets the requirements. If not, it is determined that the photographing mode does not belong to the recommended photographing mode. If so, proceed to the next step.

[0096] S14 determines the matching usage period whose historical shooting time is greater than the preset time length through the historical shooting time of different matching usage periods, and judges whether the number of matching usage periods whose historical shooting time is greater than the preset time length meets the requirement. If not, it is determined that the photographing mode does not belong to the recommended photographing mode. If so, proceed to the next step.

[0097] S15 determines the photographing pass rate of different matching usage periods according to the image pass rate and the number of qualified images in different matching usage periods, determines the photographing timeliness of different matching usage periods based on the historical photographing time of different matching usage periods, determines the comprehensive reliability coefficient of the photographing mode according to the photographing pass rate and the photographing timeliness of different matching usage periods, and determines the recommended photographing mode using the comprehensive reliability coefficient.

[0098] S4 uses the recommended photographing mode to acquire the fundus image of the user, and determines whether it is necessary to switch the photographing mode based on the analysis result of the fundus image and the position change of the user.

[0099] Specifically, determining whether it is necessary to switch the camera mode includes:

[0100] Acquire multiple fundus images using a preset number of fundus images, determine image clarity of the fundus images based on analysis results of the fundus images, determine qualified fundus images among the fundus images using the image clarity, and determine image quality of the fundus images according to the number of qualified fundus images and the image clarity of different qualified fundus images;
