Problems solved by technology

However, it is highly difficult to perform surgical operations with the extremely limited field of view of the endoscope, and foreign objects in the patient's body will inevitably stick to the lens of the endoscope, and sometimes, the flushing system of the endoscope will not be flushed out. The situation of foreign bodies will cause the originally narrow vision to become more blurred, which will affect the doctor's judgment

Embodiment Construction

[0023] Introduce a kind of endoscope signal processing method provided by the present invention below in conjunction with accompanying drawing:

[0024] see figure 1 , a kind of endoscopic signal processing method provided by the present invention, comprises the steps of following sequence:

[0025] S1. Image generation, a plurality of images generated through time-series imaging of the subject;

[0026] S2. The main and auxiliary images are determined, and one image is selected as the main image according to the static image generation instruction, and multiple images are used as the auxiliary image group;

[0027] S3. Contour extraction, extracting contour components from the main image and the sub-image;

[0028] S4. Judgment of foreign objects on the lens. Determine whether there are foreign objects on the lens according to the relative position of the contour components in the image. If there are foreign objects, perform step S5. If there are no foreign objects, determi...

Abstract

The present invention relates to an endoscope signal processing method and system. The method comprises: determining whether there is a foreign object on the lens; if there is the foreign object, intercepting a picture corresponding to the foreign object in the main image and splicing the picture with the main image; detecting the spliced coincidence; and selecting the highest coincidence of the main composite image as the output image. The method disclosed by the present invention can reduce the impact of the foreign bodies on the lens on the endoscopic images, so that medical personnel can obtain a clearer and more comprehensive picture, and the diagnosis and treatment can be facilitated.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an endoscope signal processing method and system. Background technique [0002] In recent years, surgical operations using an endoscope, such as laparoscopic surgery and thoracoscopic surgery, have been attracting attention. Endoscopic surgery is advantageous because it does not require laparotomy, thoracotomy, etc., and only two or three holes a few centimeters in diameter need to be made for inserting the endoscope and surgical tools, thus significantly easing the application of burden on patients. However, it is highly difficult to perform surgical operations with the extremely limited field of view of the endoscope, and foreign objects in the patient's body will inevitably stick to the lens of the endoscope, and sometimes, the flushing system of the endoscope will not be washed away The situation of foreign bodies will cause the originally narrow vision to become more bl...
