Problems solved by technology

However, on the one hand, this monitoring system can only monitor the colonoscopy quality of some samples in a specific period of time, and cannot cover every examination; Withdrawing the mirror quickly at the beginning, and slowing down to meet the standard at the end, this caused the doctor to not observe the patient's distal colon in place, and wasted a lot of unnecessary time in the proximal colon

Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] seefigure 1 , the invention discloses a computer vision-based method for real-time monitoring of the speed of withdrawing the mirror from the colonoscope, which comprises the following steps:

[0050] S1, obtain the real-time video of the colonoscopy through the endoscopic inspection equipment, decode the video into a picture (2 frames per second), and cut the picture to a size of 360×360 pixels. In order to only retain the structural information of the picture, the picture needs to be further processed shrink;

[0051] A 360*360 picture has more than 100,000 pixels, which contains a huge a...

Abstract

The invention provides a real-time monitoring method and system for the enteroscope retreating speed based on computer vision. the enteroscope retreating speed and stability are actively prompted to adoctor, the doctor is reminded when the speed is overspeed or a picture is unstable, the doctor is supervised to control the enteroscope retreating speed within a safe range all the time, and the enteroscope examination quality is improved. The perception Hash algorithm technology is adopted, the enteroscope withdrawing speed is reflected in real time by analyzing the stability of the enteroscopeimage instantly or for a period of time, a doctor is reminded to control the enteroscope withdrawing speed within the safety range all the time during enteroscope examination, and the detection comprehensiveness and effectiveness are improved.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method and a system for monitoring the withdrawal speed of a colonoscope under a colonoscope. Background technique [0002] Colonoscopy is the most common examination method for detecting colorectal polyps, tumors and other lower gastrointestinal lesions. Colonoscopy withdrawal time refers to the actual time from when the colonoscopy reaches the cecum to when the colonoscopy is withdrawn to the anal canal, minus the time for additional operations such as dyeing examination or biopsy. Studies have shown that the detection rate of polyps, the detection rate of adenomas and the average number of polyps found per subject in colonoscopy patients increase significantly with the prolongation of withdrawal time[1,2]. Therefore, the colonoscopy operation guidelines of various countries regard the withdrawal time as an important quality control index. American guidelin...
