Problems solved by technology

Most of the existing cigarette appearance inspections are to take still pictures, either take multiple pictures from different angles, or take pictures with multiple cameras, and then compare them with the standard samples one by one, which usually cannot be compared at one time, or Unable to provide more automated evaluation results for cigarette appearance and stamp inspection

Abstract

The invention discloses a cigarette appearance detection method and device, equipment and system and a medium. The method comprises the steps: acquiring a 360-degree scanning panoramic image of the outer surface of a to-be-detected cigarette; preprocessing the panoramic image to remove noise, and segmenting the preprocessed panoramic image to find a target area; and comparing the corresponding image in the target area with a standard image to obtain corresponding similarity so as to generate appearance quality evaluation and defect information corresponding to the to-be-detected cigarette. According to the invention, image distortion can be reduced, the detection accuracy is improved, shooting of a plurality of pictures or shooting by a plurality of cameras is not needed, and a more automatic evaluation result can be provided for cigarette appearance and steel seal detection in time.

Description

technical field [0001] The invention relates to the technical field of cigarette quality inspection, in particular to a cigarette appearance inspection method and its device, equipment, system and medium. Background technique [0002] During the production process of cigarettes, surface defects or printing stamp defects are often caused by human or equipment reasons, which have become a major category of problems that account for the largest proportion of finished cigarette quality. Most of the existing cigarette appearance inspections are to take still pictures, either take multiple pictures from different angles, or take pictures with multiple cameras, and then compare them with the standard samples one by one, which usually cannot be compared at one time, or It is impossible to provide more automated evaluation results for cigarette appearance and stamp inspection. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purp...
