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

The invention relates to the technical field of image processing, and discloses an automatic label welding method and device based on multiple steel bundles, and the method comprises the steps: firstly obtaining an end face image of a to-be-welded steel bundle, extracting the end face contour of each piece of steel from the end face image of the to-be-welded steel bundle, and obtaining the centralpoint coordinates of the end face contour of each piece of steel; conducting expansion processing on the end face images of the to-be-welded steel bundles, and extracting the outer contour of each steel bundle; according to the center point coordinates of the end face contour of each steel material and the outer contour of each steel bundle, obtaining the end face contours of all the steel materials corresponding to each steel bundle; obtaining a to-be-welded point set of each steel bundle according to the end face contours of all the steel materials corresponding to each steel bundle; and welding the sign according to the to-be-welded point set of each steel bundle. Before the label welding points are selected, the outer contours of the overlapped and crossed steel bundles are extracted,all steel materials to which the steel bundles belong are divided, and the selection precision of the subsequent label welding points is improved.

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...
