A method, medium, and device for estimating the length of pipeline cracks based on video images

Abstract

The present invention relates to the field of image processing technology, specifically to a method, medium, and device for estimating the length of pipeline cracks based on video images. The method comprises the steps of A, extracting images with cracks from acquired pipeline videos, and making them into a dataset; B, establishing a segmentation model to segment the images in the obtained dataset to obtain crack images containing only cracks; C, marking the crack image to obtain the center coordinate of the crack images; D, obtaining the coordinate of all the pixels on the crack from the crack image, and calculating the length of the crack based on the obtained coordinates of the center and all pixels on the crack. This invention can overcome the challenges of quantifying crack length caused by the shooting angle, enabling the measurement of crack length on the inner wall of the pipeline using only pipeline inspection images. This significantly improves the accuracy of crack length quantification and provides a reference basis for further repair of drainage pipelines.
