All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, an embodiment of the present invention provides a fundus inspection system, which includes a user terminal 1, a server 2, and a plurality of fundus cameras 3, wherein the user terminal 1 may be a portable mobile device, such as a personal smart phone; the server 2 is a dedicated device deployed by a service provider, and the server is a general term for a service device deployed at a remote location, and it should be understood by those skilled in the art that in practical application, a variety of servers, such as an IOT (Internet of Things) server, a data storage server, and the like, need to be set according to a use, so that the server described in the present application may be understood as a server or a cluster formed by a plurality of servers. The server 2 is connected to the terminal 1 and each fundus camera 3 through the internet. The fundus camera 3 is an electronic apparatus having an optical element, an imaging device, and a communication device. The system can adopt a self-photographing type fundus camera disclosed in Chinese patent document CN209826671U, so that a user can take self-photographing fundus pictures by holding or wearing the system.
The user terminal 1 is used to provide personal identification. The user needs to register when using the system for the first time, personal information of the user is filled in an interactive interface provided by the system and is submitted to the server 2 to establish a personal account, and the server 2 allocates a personal identification for the registered user, wherein the personal identification can be a string of numbers, letters or a combination of the numbers and the letters.
As a preferred embodiment, the server 2 sends an invitation to the user terminal 1 for a fundus examination, for example a corresponding invitation link may be displayed to the user by means of a web page, a public number, an application interface, etc. The user can choose to accept the invitation, and the user terminal 1 acquires personal information input by the user, such as basic information including the user name, age, sex and the like, and responds to the fundus examination invitation; after receiving the response (after receiving the personal information), the server 2 assigns a personal identifier to the user and transmits the personal identifier to the user terminal 1, and establishes a personal account.
The fundus camera 3 is used to acquire a personal identification from the user terminal 1 and transmit the personal identification to the server 2. The fundus camera 3 can obtain the personal identification from the user terminal 1 in various ways, such as communication via wireless network, bluetooth, short-range electromagnetic signal communication, etc., and accordingly, a sensor supporting this communication way is provided in the fundus camera 3, by which the personal identification in the user terminal 1 can be obtained.
As a preferred embodiment, the user terminal 1 represents the personal identification by displaying a two-dimensional code, and the fundus camera 3 is provided with a two-dimensional code scanning device, and the personal identification is obtained by scanning the two-dimensional code and analyzing. The two-dimensional code scanning device may be an independent scanning device disposed outside the camera housing, such as a camera dedicated to scanning two-dimensional codes. In order to improve the integration level and make the entire fundus camera simpler, the present embodiment uses the lens for taking the fundus image in the fundus camera to take the two-dimensional code. Specifically, the camera is in a standby state in which the focal length of the lens is suitable for photographing the size of the two-dimensional code displayed on the screen of the user terminal 1.
The server 2 transmits a start instruction to the fundus camera 3 after receiving the personal identification. In practical application, the server 2 will also verify the personal identifier, determine whether the received personal identifier is from a registered user, thereby verifying the user identity, and issue a start instruction after the verification is passed. In addition, since a plurality of fundus cameras 3 may exist simultaneously in the network, in order for the server 2 to determine to which camera the startup instruction should be sent, the fundus camera 3 also needs to send its device serial number to the server in order for the server 2 to determine its network address, physical address, and the like. The fundus camera 3 may transmit its own device serial number while transmitting the user personal identification, or may transmit the device serial number after waiting for the server 2 to verify the personal identification, and then wait for notification from the server 2.
The fundus camera 3 enters a working state after receiving the starting instruction, so that a user can take fundus pictures by operation. This is a remote wake-up process, where the user activates the fundus camera indirectly through the smartphone and server, rather than operating the fundus camera directly. According to the camera structure of the present embodiment, the user can take a picture of the fundus by himself after the camera is started, and then the fundus camera 3 transmits the picture of the fundus to the server 2. Of course, the present invention is not limited to the use of a self-photographing type fundus camera, and is applicable to the use of a large-sized fundus camera having a more complicated structure, or a fundus camera that requires others to hold to photograph a patient.
The server 2, after receiving the fundus picture, stores it in an account registered by the user, that is, stores the fundus picture and the personal information in association with each other. In practical application, the data storage server can be used, a user can access the server 2 to view the fundus picture of the user by using any terminal, and the server 2 can also actively send the fundus picture to the user terminal 1.
As shown in fig. 2, when the user uses the present system of the present embodiment, each device performs operations including:
S1A, the user terminal 1 provides personal identification and informs the server 2;
S2A, the fundus camera 3 acquires a personal identification from the user terminal 1;
S3A, the fundus camera 3 sends a personal identification to the server 2;
S4A, the server 2 sends a start instruction to the fundus camera 3;
S5A, the fundus camera 3 enters a working state after receiving the starting instruction, so that the user can take fundus pictures through operation;
S6A, the fundus camera 3 takes a fundus picture and sends it to the server 2;
S7A, the server 2 transmits the fundus picture to the user terminal 1, or stored in a user account in the server 2.
According to the fundus examination system provided by the embodiment of the invention, a user only needs to use the personal terminal to provide the personal identification, the server remotely starts the fundus camera to acquire the personal identification of the user, the server sends a starting instruction to wake the fundus camera to enter a working state after acquiring the personal identification, the user can shoot fundus pictures and store the shot fundus pictures in the server, and the user can use the personal terminal to acquire the fundus pictures of the user. The system converts the operation of the user on the eye fundus camera into the operation on the personal terminal, thereby reducing the difficulty of man-machine interaction and avoiding overhigh cost caused by arranging too many interaction devices in the eye fundus camera. As a service manufacturer, the fundus cameras can be deployed at a plurality of places, all the fundus cameras can be served simultaneously by deploying a small amount of server equipment remotely, professional medical staff do not need to intervene in a photographing scene, the system can be separated from a medical institution to be managed and used by ordinary staff, and popularization of examination on fundus health is facilitated.
For the self-timer type fundus camera, after being remotely started up by the server 2, the user may also be given more prompts in steps S2A, S5A to ensure that the photographing process proceeds smoothly. In a preferred embodiment, the fundus camera 3 is provided with a voice playing device for playing voice to guide the user to manipulate the fundus camera 3 according to the set flow. Specifically, the boot process of the present embodiment includes: step S2a1 of prompting the user to align the two-dimensional code displayed by the user terminal 1 with the lens of the fundus camera 3, or prompting the user to turn on a communication unit (wireless network, bluetooth, NFC, or the like) of the user terminal 1 so that the fundus camera 3 reads the personal identification; step S5a1 of prompting the user to place the fundus camera 3 in a darkroom or at no light; step S5A2, prompting a user to place eyes in a shooting position, and simultaneously amplifying eye sockets by using two hands to expose eyeball in front of a shooting opening to the maximum extent; step S5A3, prompting a user to rotate the eyeball according to the direction of the light source in the camera; in step S5a4, after taking a fundus picture of one eye is completed, the user is prompted to switch to the other eye.
Further, in order to ensure that the user can correctly manipulate the fundus camera 3 for self-photographing, the fundus camera 3 is also provided with a sensing device in a preferred embodiment to sense manipulation information generated by the user's manipulation of the fundus camera 3. For example, a light sensor for sensing ambient light to generate ambient light intensity information, which can be changed by a user's manipulation since the fundus camera 3 can be moved by the user, and/or a distance measuring device may be provided, and the ambient light intensity information is regarded as a kind of manipulation information.
The distance measuring device is used for detecting the distance between the eyeball of a user (a shot object) and the lens (the ocular lens of the eye ground camera) and generating distance information according to the distance, and specifically can be an infrared distance measuring device or a shooting distance measuring device, and the distance information is generated by detecting the distance between the eye and the ocular lens at a shooting position (near the ocular lens) of the eye ground camera 3. Since the user can adjust the positional relationship with the fundus camera 3 by himself, the distance information is regarded as a kind of manipulation information.
The fundus camera 3 can automatically judge whether the above-mentioned ambient light intensity information and distance information meet the set standard, and control the prompting process according to the above-mentioned information. Specifically, for example, in the step S5a1, the light sensor is activated and it is determined whether the ambient light intensity information is smaller than the set intensity value, when the ambient light intensity information is smaller than the set intensity value, the step S5a2 is executed to determine that the current environment meets the shooting requirement, otherwise, the step S5a1 is stopped, and the user is continuously prompted to adjust the shooting environment; for example, in step S5a2, the distance measuring device is activated to determine whether the distance information is between the upper threshold and the lower threshold, that is, whether the distance between the eye and the eyepiece is too close or too far, and when the distance information is between the upper threshold and the lower threshold, the current distance is considered to be in accordance with the shooting requirement, step S5A3 may be executed, otherwise, step S5a2 is stopped, and the user is prompted to change the distance between the eye and the eyepiece.
In a preferred embodiment, the above-described operation of determining the environment and the distance is performed by the server 2, that is, the fundus camera 3 is used only to acquire the manipulation information and transmit it to the server 2. The server 2 determines from the light intensity information whether the environment in which the fundus camera 3 is located can take a fundus picture, and determines from the distance information whether the fundus camera 3 can take a fundus picture. Performing the calculation remotely by the server 2 reduces the amount of calculation of the fundus camera 3, whereby it is possible to reduce the cost of the fundus camera 3 and improve portability.
The embodiment of the invention provides another fundus examination system which comprises a user terminal 1, a server 2 and a plurality of fundus cameras 3, and the fundus examination system is added with a function of detecting fundus pictures on the basis of the system of the embodiment. Specifically, after receiving the fundus picture, the server 2 of the present embodiment uses the trained machine learning model to identify (including classification, segmentation, and regression prediction) the fundus picture, and obtains and stores a detection result in an account registered by the user, where the detection result may be a segmentation result of an object of interest in the fundus picture, a classification result of a category to which the fundus picture belongs (for example, belonging to health or a certain disease), or a regression prediction result of a body index related to the fundus picture (for example, age, diopter, and the like). The user can use any terminal to access the server 2 to check the detection result of the user, and the server 2 can also actively send the detection result to the user terminal 1.
In order to make the detection performed by the server 2 more targeted, the personal information transmitted or confirmed by the user terminal 1 of the present embodiment includes medical history information and/or symptom information. Specifically, the medical history information includes several questions and options-whether there is diabetes, whether there is hypertension, whether there is cardiovascular and cerebrovascular disease, whether there is high myopia, whether there is history of eye surgery; symptom information includes several questions and options-whether vision is degraded, whether there is edema in the eyes, whether there is bleeding in the eyes, whether there is a symptom of a fissure.
When the server 2 receives the information, the detection mode of the fundus picture is determined according to the information, for example, the detection area is determined, or a suitable machine learning model is selected to detect the fundus picture, so that the detection result is more accurate. The reason for this is that, in order to comprehensively detect various possible fundus diseases, a service manufacturer may train a plurality of models for different disease types and a plurality of models for different regions of the fundus oculi, and at the same time, the service manufacturer may train a multi-disease identification model for some common ocular diseases, for example, a machine learning model disclosed in chinese patent document CN108596895A may realize multi-disease detection. The advantages of a plurality of models are different, for example, some models have more detailed identification aiming at the characteristics of diabetic retinopathy, and the severity grade of the pathological changes can be detected; some models are more comprehensive, and can screen various fundus diseases simultaneously; some models only detect the optic disc region and only identify glaucoma. In this case, the detection efficiency using all models for each fundus picture of the user is low, so the embodiment represents the actual situation of the user by the medical history information and/or symptom information, and the server selects a part of models for the actual situation of the user to recognize the fundus picture thereof, thereby improving the detection efficiency.
For example, when the personal information of the user shows that the user does not have any medical history or symptoms, a plurality of disease identification models can be used for roughly detecting some common disease features, and the detection by using a model for a certain disease is not needed; for example, when the user has diabetes mellitus in personal information, the fundus picture can be detected by using a model special for detecting characteristics of diabetic retinopathy, so that the detection result is more detailed.
The above example is only for clearly explaining how the server 2 performs the targeted detection, and is not limited to the model selection logic, and other selection strategies may be set in practical application.
In an alternative embodiment, the server 2 may further determine the photographing quality of the fundus picture, for example, the server 2 may perform stain/bright spot detection, exposure detection, sharpness detection, light leakage detection, local shadow detection, and the like on the fundus picture by using an image detection method disclosed in chinese patent document CN108346149A, and send a prompt message to the user terminal 1 when it is determined that the photographing quality does not meet the preset standard, so as to prompt the user to operate the fundus camera 3 again to take the fundus picture thereof.
As shown in fig. 3, when the user uses the present system of the present embodiment, each device performs operations including:
S1B, the user terminal 1 provides personal identification and informs the server 2;
S2B, the fundus camera 3 acquires a personal identification from the user terminal 1;
S3B, the fundus camera 3 sends a personal identification to the server 2;
S4B, the server 2 sends a start instruction to the fundus camera 3;
S5B, the fundus camera 3 enters a working state after receiving the starting instruction, so that the user can take fundus pictures through operation;
S6B, the fundus camera 3 takes a fundus picture and sends it to the server 2;
S7B, the server 2 detects the fundus picture to obtain the detection result, and the detection in the step comprises the detection of the fundus disease and the detection of the fundus picture quality.
S8B, the server 2 transmits the fundus picture and the detection result to the user terminal 1, or stored in a user account in the server 2.
The server in the fundus examination system provided by the embodiment of the invention detects the fundus picture to obtain the detection result about the disease, and the user can check the fundus picture and the detection result through the personal terminal, so that the user can efficiently and timely know the eye health state of the user, the convenience of ophthalmic examination is improved, and the detection result can be referred by medical staff, thereby saving the medical cost.
