In an embodiment of the present invention, the determining whether there is an associated abnormal blood vessel associated with the retinal blood vessel within a preset range around the first breakpoint includes: acquiring an extension line of the central line of the retinal blood vessel with the first breakpoint as an end point, wherein the extension line is a ray extending according to the extension trend of the central line; judging whether intersection points exist between the extension lines and the edge lines or the center lines of other retinal blood vessels in a preset range, and determining the retinal blood vessels with the intersection points as intersected retinal blood vessels; and judging whether a breakpoint exists on the central line of the intersected retinal blood vessels, and determining the intersected retinal blood vessels with the breakpoints as associated abnormal blood vessels associated with the retinal blood vessels.

Further, after the relevant abnormal blood vessel is highlighted in the current window of the computer, first prompt information is sent to the user, for example, inquiry information is sent to the user whether automatic repair is needed or not.
In the embodiment of the invention, the prompt information is sent to the user after the associated abnormal blood vessel is highlighted, so that the user can check the associated abnormal blood vessel again to avoid error detection caused by the identification error of the computer, and the user can freely select whether to process the currently detected associated abnormal blood vessel, thereby avoiding the error detection caused by the identification error of the computer, improving the accuracy of automatic detection, improving the operation freedom of the user and improving the user experience.
In an embodiment of the present invention, the editing the retinal blood vessel based on the first feedback information to generate an edited retinal blood vessel includes: deleting the related information of the retinal blood vessel and the related abnormal blood vessel under the condition that the first feedback information is an ignoring instruction; in the case that the first feedback information is a modification instruction: determining a breakpoint closest to the first breakpoint on the central line of the associated abnormal blood vessel as a second breakpoint; respectively taking the first breakpoint and the second breakpoint as a first endpoint and a second endpoint, and generating a corresponding relation between the first endpoint and the second endpoint; adjusting the corresponding relation to generate an edited blood vessel central line; generating the edited retinal vessel based on the edited vessel centerline.
In a possible implementation mode, after observing the highlighted associated abnormal blood vessel, the user finds that the associated abnormal blood vessel belongs to the other of the two crossed retinal blood vessels, because the end point of the other retinal blood vessel is closer to the breakpoint of the currently disconnected retinal blood vessel, the associated abnormal blood vessel is falsely detected by the computer as the associated abnormal blood vessel associated with the current retinal blood vessel, so that the user chooses to ignore the associated information, and the computer automatically deletes the associated information so as to avoid prompting the user again, causing troubles to the user and reducing the user experience.
In another possible embodiment, the user feeds back an instruction to modify the retinal vessel to the computer by observing the highlighted associated abnormal vessel, for example, clicking a "repair" option in a dialog box popped up in the current view, at which time the computer determines the breakpoint closest to the first breakpoint D1 on the centerline of the associated abnormal vessel where the breakpoint exists as the second breakpoint D4, and takes the first breakpoint D1 and the second breakpoint D4 as the first endpoint P1 and the second endpoint P2, respectively, and generates a correspondence between the first endpoint P1 and the second endpoint P2, for example, a set of points connecting the first endpoint P1 and the second endpoint P2, as shown in fig. 4.

In an embodiment of the present invention, the editing method further includes: acquiring a second control point input by a user, and optimizing the edited blood vessel central line based on the second control point to generate an optimized blood vessel central line; generating the edited retinal vessel based on the optimized vessel centerline.
Referring to fig. 6, in another possible embodiment, the edited blood vessel centerline obtained after the adjustment of the correspondence relationship by inputting a control point still does not conform to the shape of the current blood vessel, so that the second control point K2 input by the user is obtained, the edited blood vessel centerline is optimized according to the control point K2, and thus the optimized blood vessel centerline is obtained, and then the computer automatically generates the edited retinal blood vessel according to the optimized blood vessel centerline.
In the embodiment of the present invention, based on the same principle, a user may add any number of control points in the current retinal area according to actual needs, so as to adjust the correspondence for multiple times, so that the generated blood vessel centerline is more consistent with the form of the current retinal blood vessel, which all shall belong to the protection scope of the present invention, and no redundant description is given here.
