Embodiment Construction

[0090] The first embodiment of the present application discloses an automatic welding label method based on multiple steel bundles, see figure 1 As shown in the schematic diagram of the workflow, the method includes:

[0091] Step S101 , acquiring an end face image of a steel bundle to be welded, where at least one steel bundle is included in the steel bundle to be welded.

[0092] The end face image of the steel bundle to be welded is collected by a binocular camera, the binocular camera includes a first camera and a second camera, and the collected end face image includes the first end face image collected by the first camera and the second camera Acquired second end face image.

[0093] Step S102, extracting the end surface profile of each steel material from the end surface image of the steel bundle to be welded, and obtaining the center point coordinates of the end surface profile of each steel material.

[0094] Based on the first end face image and the second end face...

Abstract

This application relates to the technical field of image processing, and discloses an automatic welding label method and device based on multiple steel bundles. The end face profile of the root steel, and obtain the center point coordinates of each steel end face profile; expand the end face image of the steel bundle to be welded, and extract the outer contour of each steel bundle; according to the center point coordinates of each steel end face profile and each According to the outer contour of each steel bundle, obtain the end surface contours of all steel materials corresponding to each steel bundle; obtain the to-be-welded point set of each steel bundle according to the end surface contours of all steel materials corresponding to each steel bundle; according to each steel bundle The set of welding points is to be welded for signs. In the above method, before selecting the welding points of the signs, the outer contours of the overlapping and intersecting steel bundles are extracted, and all the steel materials to which they belong are divided, so as to improve the selection accuracy of the welding points of the subsequent signs.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an automatic welding label method and device based on multiple steel bundles. Background technique [0002] After bundling and packaging the steel, the steel factory usually welds a certain number of labels on the end face of each steel bundle. These labels are used to display the basic information of the steel bundle, such as model, specification and production date. The traditional sign welding method is manual welding, which has low efficiency and cannot be applied to large-volume production. In order to improve efficiency, many steel mills have generally adopted machine control to realize automatic welding of signs. [0003] The process of automatic welding of signs generally includes: when the current steel bundle is transported to the position to be welded, the system controls the binocular camera to collect the end face image of the steel bundle, throug...
