Method and device for counting cigarette in batch size

Abstract

The invention discloses a method for batch counting the tobacco and its relative device. The method comprise: (1) pretreating the original picture; (2) operating based on the movable rectangular window and the morphological dividing method: first, filling the deformity points inside the tobacco, secondly, operating the corrosion treatment on the picture, and then, distinguishing the cigarette by subarea window matching and counting. Wherein, first, counting and eliminating the connected regions of single cigarette, secondly, moving a window (W) of D*D pixels serially in the left connected regions, while the D means the diameter of standard cigarette, then, when the number of black pixels in the window meets the amount needed by one cigarette and the number is most, operating the counting and eliminating. In addition, the device comprises a computer processing system, a digital camera, a tobacco-frame-fixing device, a gate-controlled switch and a signal-collecting card. Wherein, the digital camera is connected to the computer processing system via the I / O port and the gate-controlled switch is connected to the computer processing system via the signal-collecting card. The invention has the advantages of high speed, non-destruction and high efficient.

Description

technical field [0001] The invention belongs to the field of image recognition and measurement, in particular to a method and device for counting cigarettes in batches. Background technique [0002] In most domestic tobacco factories, cigarette rolling and packaging are two independent manufacturing links, which belong to different processes. After the cigarettes are rolled, they are put into the cigarette frame, and unqualified cigarettes are eliminated through quality inspection, and then enter the packaging process. Before entering the packaging process, it is necessary to count the number of cigarettes after quality inspection to understand the consumption and output of cigarettes in the rolling process, and use them as work assessment indicators. At present, the counting of cigarettes in cigarette factories includes manual and mechanical methods. Manual methods are labor-intensive and time-consuming, and most of them have been replaced by mechanical counting equipment...

AI Technical Summary

Problems solved by technology

Segmentation based on edge and region requires high requirements for color distribution changes. In the cigarette image, the adhesion between cigarettes is serious, making the color distribution of tobacco leaves not obvious. Therefore, these two segmentation techniques are used for identification and counting. not ideal

In conclusion, there is currently no ready-made method that can adapt to the requirements of high-precision cigarette counting in batches
