Abstract

The invention provides a Hough transform based round pipe detection method, belongs to the field of quick and intelligent detection of the industrial field, and provides a handheld detection device based on a Hough transform algorithm, aiming to solve problems about quick detection and identification methods for round pipe products in the industrial field and having effects of improving graphic detection accuracy and saving inspection time of the industrial field. The handheld detection device comprises a handheld device screen shell 1, a camera head 2, a liquid crystal display screen 3, an F1-button 4, an F2-button 5, an F3-button 6, a focal length zooming button 10 and the like. According to the Hough transform image identification algorithm, the handheld detection device can realize pipeline detection in the industrial field and accounting of the detected products; thus, requirements for detection and counting of round pipe products in large-scale production and products in line production are met, inaccuracy of the conventional image detection algorithm is overcome, and efficiency of the industrial field is improved.

Description

technical field [0001] The invention relates to an application oriented to the field of industrial field. Aiming at the requirement of machine vision identification technology of round pipe products in industrial control field and production line, a detection method of round pipe products based on Hough transformation is proposed, which belongs to the rapid and intelligent detection in industrial field. field. Background technique [0002] With the development of computer technology and information technology, image recognition technology has been more and more widely used. In response to the demand for machine vision on industrial control sites and production lines, circular tube products are detected from digital images and counted in It plays a very important role in computer vision. Many circle detection methods have been proposed one after another, the most basic and widely used one is the circle detection technology based on Hough transform. But the conventional Houg...
