Cigarette packet package appearance detection method

Abstract

The invention relates to the technical field of package detection, in particular to a cigarette packet package appearance detection method . The method comprises the following steps of: collection andstorage of standard package appearance characteristics: normally detecting at least three standard cigarette packets, performing collection to obtain standard parameters, and storing the standard parameters in a memory; on-line cigarette packet comprehensive detection to obtain detection data of all points of the cigarette packet; detection result judgment: contrasting the similarity between thecigarette packet and the standard parameters and the image position coordinate data, and judging whether the similarity and the image position coordinate data are within an allowable tolerance or not;rejection of unqualified parts, namely rejecting the unqualified parts through a self-rejecting mechanism. Compared with the prior art, the method provided by the invention has the beneficial effectsthat: the detection result is comprehensive and accurate, and the system applies a comprehensive detection technology to improve the accuracy of the detection result; the operation is simple, complexconfiguration is not needed, and manual intervention is not involved in the whole process; reflective packaging materials can be detected, a diffuse reflection mode is used for uniform illumination on cigarette packets, and the problems of corner shadows and random reflection are thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of packaging inspection, in particular to a method for inspecting the appearance of cigarette pack packaging. Background technique [0002] With the continuous advancement of science and technology, the tobacco industry has higher and higher requirements for the quality inspection of cigarette packs and packaging, which poses new challenges to inspection indicators, inspection speed, six-sided inspection, and reliability. There are many methods at home and abroad to detect the appearance of small bags based on the principle of imaging, but these detection methods have problems such as slow detection speed, inability to inspect reflective packaging materials, cumbersome settings, inconvenient adjustment, instability, and low detection accuracy. . Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a method for inspecting the appeara...
