Editing method and device of retinal vessel edge line

Abstract

The invention discloses an editing method of a retinal vessel edge line. The method includes the steps of obtaining a vessel central line, drawing a plurality of tube diameter lines on the vessel central line at equal intervals, obtaining a first end point and a second end point input by a user on the vessel edge line, judging whether a continuous line exists between the first end point and the second end point or not, obtaining a judgment result, generating the correspondence between the first end point and the second end point on the basis of the judgment result, obtaining a first control point input by the user, adjusting the correspondence on the basis of the first control point to obtain the adjusted correspondence, and editing the adjusted correspondence on the basis of the tube diameter lines to generate the edited vessel edge line. The invention further discloses an editing device of the retinal vessel edge line. By reediting the vessel edge line, the accuracy of a retinal vessel image is improved; meanwhile operation is simple, operation steps are few, working content is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a method and an editing device for edge lines of retinal blood vessels. Background technique [0002] With the continuous breakthrough and large-scale application of computer technology, it has become the norm in the industry to pre-process the data collected by medical equipment through computers to reduce the workload of doctors. The retinal blood vessel image in the eyeball image can automatically generate the blood vessel centerline and blood vessel edge line of the retinal blood vessel, and automatically generate the patient's condition information through calculation. [0003] However, in the actual application process, due to problems such as image contrast interference, noise interference, algorithm defects, and poor configuration adaptability, the accuracy of the retinal blood vessel images automatically generated by the computer is poor, and errors or mistakes often occur, such as i...

Problems solved by technology

[0005] In order to solve the technical problem of inaccurate drawing of retinal vessel edge lines in the prior art, an embodiment of the present invention provides an editing method and an editing device for retinal vessel edge lines. Draw a plurality of caliber lines at equal intervals on the blood vessel center line, wherein each of the multiple caliber lines is perpendicular to the blood vessel center line; obtain the user input on the blood vessel edge line The first end point and the second end point, judging whether there is a continuous line between the first end point and the second end point, and obtaining a judgment result; based on the judgment result, generating the first end point and the The corresponding relationship between the second end points; obtain the first control point input by the user, and adjust the corresponding relationship based on the first control point to obtain the adjusted corresponding relationship; based on the plurality of pipe diameter line pairs The adjusted corresponding relationship is edited to generate an edited vessel edge line
