Problems solved by technology
[0003] None of the currently used cigarette makers has a visual inspection device for the appearance of cigarettes. The appearance quality of cigarettes can only be observed and processed manually. Due to the high production speed of cigarette makers, it is impossible for humans to find and solve problems in time, resulting in comparison. The quality of cigarettes is a big hidden danger, and the quality of cigarettes reflects the brand value of cigarettes. All cigarette companies are eager to solve the above problems

The invention discloses a machine-vision-based visual cigarette appearance inspection device of a cigarette making machine. The machine-vision-based visual cigarette appearance inspection device comprises an optical image-forming unit, an image pre-processing unit, a control and image analyzing unit and a trigger signal unit, wherein the optical image-forming unit comprises a camera component A and a camera component B which are respectively positioned on the two side surfaces of a transmission drum wheel of the cigarette making machine; the image pre-processing unit comprises a PCI image acquisition card with a CAMLINK interface; the control and image analyzing unit mainly comprises an industrial computer; the trigger signal unit mainly comprises FPGAs; the optical image-forming unit, the image pre-processing unit, and the control and image analyzing are connected one by one; and the trigger signal unit is simultaneously connected to the optical image-forming unit, the image pre-processing unit, and the control and image analyzing unit. Cigarette images acquired by the device include images of a tipping paper filter tip part, so that complete finished product cigarettes can be inspected.
Description
technical field [0001] The invention relates to tobacco machinery, in particular to a machine vision-based visual detection device and detection method for the appearance of cigarettes in cigarette making machines. Background technique [0002] Machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system refers to converting the ingested target into an image signal through a machine vision product (that is, an image capture device, which is divided into two types: CMOS and CCD), and sending it to a dedicated image processing system. The image system performs various calculations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. [0003] None of the currently used cigarette makers has a visual inspection device for the appearance of cigarettes. The appearance quality of cigarettes can only be observed and processe...
