Method for detecting lack and upending of cigarettes in cigarette packet on basis of machine vision technology

Abstract

The invention discloses a method for detecting lack and upending of cigarettes in a cigarette packet on the basis of the machine vision technology. The method comprises the following steps: an image sensor is adopted for shooting the filter-tip end surface of the cigarette packet, and a forward image of the filter-tip end surface is shot by the image sensor; when the cigarette packet is lack of cigarettes, areas with the brightness becoming low obviously can occur in the image shot by the image sensor, the image is obviously different from a white image of the normal filter-tip end surface by contrast, and a computer can judge that the cigarette packet is lack of the cigarettes; if upended cigarettes exist in the cigarette packet, an image of a cigarette-tobacco end surface is shot by the image sensor and is obviously different from the white image of the normal filter-tip end surface by contrast, and the computer can judge that the upended cigarettes exist in the cigarette packet.

Description

technical field [0001] The invention relates to the field of cigarette pack detection methods, in particular to a cigarette pack detection method using machine vision technology, in particular to a machine vision technology-based cigarette pack missing and reverse count detection method. Background technique [0002] In the process of cigarette processing and production, reasons such as the blockage of the cigarette storehouse on the packaging line may cause lack of cigarettes (missing branches) in the final produced cigarette pack. In addition, cigarettes may be reversed during the process of being transported from the crimping machine to the packaging line, resulting in cigarettes being reversed (reversed) in the final cigarette pack. In order to ensure the quality of the final cigarette pack, it is necessary to install a cigarette pack missing detector on the cigarette packaging line to detect whether there are defects such as missing and reversed counts in the cigarette ...
