Document Type and Number:
WIPO Patent Application WO/2024/124707
Kind Code:
A1
Abstract:
Disclosed in the present invention is a bend angle measuring method for bent pipe machining. The measuring method comprises the following steps: carrying out binarization and region-of-interest extraction on an image to be recognized, so as to obtain binarized images of two straight line segment regions, the image to be recognized being an image of a machined bent pipe; and, according to the binarized images of the two straight line segment regions, calculating a bend angle. The image-based online bend angle measuring method and system provided by the present invention have the advantages of low cost, high efficiency and high universality.
