AI Technical Summary

Technical Problem

During the actual image acquisition process of digestive endoscopy, the continuous peristalsis of the digestive cavity and the interference of contents make it difficult for traditional static distortion correction templates to adapt to the real-time changing environment, resulting in poor real-time image distortion correction effect during digestive endoscopy.

Method used

By acquiring the current endoscopic image and its consecutive frames during digestive endoscopy, the influence of contents and tangential distortion at each pixel is determined. Dynamic distortion correction methods, including gradient value fitting, optical flow detection, and peristalsis rate analysis, are used to quantify the impact of contents and peristalsis in the digestive cavity on the image and perform real-time distortion correction.

Benefits of technology

It effectively improves the distortion correction effect of real-time images during gastrointestinal endoscopy, overcomes the shortcomings of traditional methods in dynamic environments, and improves the adaptability and accuracy of image distortion correction.
