AI Technical Summary

Technical Problem

In the prior art, the alignment detection of the rod ends at the fixed-scale baffle is achieved by using manual visual inspection, which has problems of accuracy and low efficiency.

Method used

By collecting the end image of the rod at the fixed scale baffle, the shadowed area is detected, the extension area corresponding to each shadowed area is determined, and whether there is a rod end in the extension area is determined. The shadow area where the rod end is present in the extension area is determined as a rod missing area. Finally, whether there is an unaligned rod at the fixed scale baffle is determined based on whether there is a rod missing area.

Benefits of technology

The accuracy and efficiency of the alignment detection of the rod ends at the fixed-size baffle is greatly improved, and unmanned automatic bar ruler shearing is achieved.

Abstract

The present invention discloses a bar end alignment detection method and device based on image processing, wherein the method comprises: collecting a bar end image at a fixed-length baffle; detecting one or more shadow areas in the bar end image; determining an extension area corresponding to each shadow area in the bar end image; judging whether there is a bar end in the extension area corresponding to each shadow area, and determining the shadow area where the bar end exists in the extension area as a bar missing area; and determining whether there is an unaligned bar at the fixed-length baffle according to whether there is a bar missing area in the bar end image. The present invention can greatly improve the accuracy and efficiency of bar end alignment detection at the fixed-length baffle, and realize unmanned automated fixed-length cutting of bars.
