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 objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0049] See figure 1 The present invention discloses a computer vision-based method for real-time monitoring of colonoscopy withdrawal speed, which includes the following steps:

[0050] S1. Obtain real-time video of colonoscopy through the endoscopy device, decode the video into a picture (2 frames per second), and crop 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 Shrink

[0051] A 360*360 picture has more than 100,000 pixels, contains a huge amount of information, and many details need to be processed. ...

Abstract

The invention provides a computer vision-based method and system for real-time monitoring of the speed of retracting the colonoscope, which actively prompts the doctor to withdraw the speed and stability of the mirror, and reminds the doctor when the speed is too high or the picture is unstable, and the supervising physician always controls the speed of retracting the mirror. Within the safe range, improve the quality of colonoscopy examination. The present invention adopts perceptual hash algorithm technology, and by analyzing the stability of the colonoscope image instantaneously or within a period of time, it reflects the speed of the colonoscope retraction in real time, so as to remind the doctor to always control the retraction speed within the safe range during the colonoscopy examination. Improve the comprehensiveness and effectiveness of detection.

Description

Technical field [0001] The invention belongs to the field of information technology, and specifically relates to a method and system for monitoring the withdrawal speed of the colonoscope under the colonoscope. Background technique [0002] Colonoscopy is the most common method to find colorectal polyps, tumors and other lower gastrointestinal diseases. Colonoscopy withdrawal time refers to the actual time between entering the cecum and withdrawing the mirror to the anal canal during the colonoscopy process, minus the time for additional operations such as staining or biopsy. Studies have shown that with the extension of the time of withdrawal, the polyp detection rate, adenoma detection rate and the average number of polyps found per subject have increased significantly in colonoscopy patients [1,2]. Therefore, in the colonoscopy operation guidelines of various countries, the withdrawal time is an important quality control indicator. The U.S. guidelines recommend that colonosc...
