Description

Cigarette appearance detection method, controller, device and storage medium Technical Field The disclosure relates to the technical field of tobacco detection, in particular to a method, a controller, a device and a storage medium for detecting the appearance of cigarette. Background In the tobacco industry, the cigarette products of each cigarette factory leave the outlet of the packaging machine and are finally transported to a case sealer through a conveying system such as a lifter, a cigarette conveying machine, a bag discharging machine and the like. Before the cigarettes enter the case sealer for case sealing and forming, appearance quality detection and rejection of the cigarettes are carried out only by the cigarette appearance detection device on the entrance conveying channel of the case sealer. The cigarette appearance detection device is particularly important as the only automatic detection procedure on the whole production line. In the related art, for each direction of the opposite cigarettes, the cigarette appearance detecting device judges defective cigarettes and rejects them. The cigarette outlet directions of the cigarettes produced by the high-speed packaging machine and the medium-speed packaging machine are opposite, so that the cigarettes cannot enter the same box sealing machine at the same time, and the quality detection is carried out by the same set of cigarette appearance detection devices. In the related art, in order to solve the above-mentioned problem, generally rely on independently installing a strip cigarette outward appearance check out test set at packagine machine, detect the strip cigarette product of this packagine machine respectively, perhaps install a strip cigarette steering device, guarantee that the strip cigarette of packagine machine of different models goes out the cigarette direction unanimously, guarantee that the strip cigarette that gets into case sealer strip cigarette outward appearance check out test set only has a direction, rely on current strip cigarette outward appearance check out test set again and detect. The method increases the production cost and causes resource waste. Disclosure of Invention The technical problem solved by the present disclosure is that the method for detecting the appearance of the cigarette in the related art increases the production cost and causes the waste of resources. According to one aspect of the disclosure, there is provided a method of detecting an appearance of a strip cigarette, comprising obtaining an image of the strip cigarette on a strip cigarette transportation device, determining a placement state of the strip cigarette from the image of the strip cigarette, determining an appearance detection algorithm corresponding to the placement state, and performing appearance detection on the strip cigarette by the appearance detection algorithm to determine whether the strip cigarette is acceptable. In some embodiments, the placement states include a first placement state and a second placement state, wherein the first placement state is different from the second placement state. In some embodiments, determining the appearance detection algorithm corresponding to the placed state includes determining the appearance detection algorithm corresponding to the placed state to be a first appearance detection algorithm if the placed state of the cigarette is a first placed state, and determining the appearance detection algorithm corresponding to the placed state to be a second appearance detection algorithm if the placed state of the cigarette is a second placed state. In some embodiments, the appearance detection algorithm is used for detecting the appearance of the cigarettes to determine whether the cigarettes are qualified or not, and the method comprises the steps of carrying out appearance detection on the cigarettes through the first appearance detection algorithm when the placement state of the cigarettes is a first placement state, determining that the cigarettes are qualified when the appearance of the cigarettes meets the appearance requirement in the first appearance detection algorithm, and determining that the cigarettes are unqualified when the appearance of the cigarettes does not meet the appearance requirement in the first appearance detection algorithm, and issuing a rejection instruction to reject the cigarettes. In some embodiments, the appearance detection algorithm is used for detecting the appearance of the cigarettes to determine whether the cigarettes are qualified or not, and the method comprises the steps of carrying out appearance detection on the cigarettes through the second appearance detection algorithm when the placement state of the cigarettes is a second placement state, determining that the cigarettes are qualified when the appearance of the cigarettes meets the appearance requirement in the second appearance detection algorithm, and determining that the cigarettes are unqualified w
