Abstract

The invention discloses a circle detection method and device, and a computer storage medium. The circle detection method comprises the steps: carrying out the edge detection of a to-be-detected image,and obtaining a plurality of edge points; combining any at least three edge points in the plurality of edge points to obtain a plurality of edge point sets, and performing circle fitting based on each edge point set to obtain a plurality of fitting circles; screening the plurality of edge points according to the contrast of the plurality of fitting circles; and performing circle fitting based ona combination formed by the reserved edge points to obtain a to-be-detected circle in the to-be-detected image. According to the circle detection method provided by the invention, the precision of thedetected circle can be ensured.

Description

technical field [0001] The present application relates to the technical field of robot vision, in particular to a circle detection method and device thereof, and a computer-readable storage medium. Background technique [0002] In actual production applications, it is necessary to use the machine vision system to realize the information extraction of circular features (referring to circular structures on the surface of workpieces / items, such as circular holes, cylinders, etc.), so as to guide production testing and realize the automation of production operations , Intelligent. [0003] The inventors of the present application found that the method in the prior art cannot guarantee the edge contrast of the found circle, and when there is interference or noise, it is easy to cause the found circle to not fit the edge. Contents of the invention [0004] The technical problem mainly solved by this application is to provide a circle detection method and its device, and a compu...
