Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.

[0027] The flow of the multi-camera array cigarette label stacked paper counting method of the present invention:

[0028] (1) Setting and adjusting the imaging device: adjust the installation position of the multi-camera array, and make the multi-camera field of view have enough overlap area, and adjust the imaging device according to the category of the current batch of products and the layer thickness, mainly including the camera position Movement, lens focus, aperture adjustment.

[0029] (2) Obtain the side image of the multi-camera array scanning cigarette label stack: Place the cigarette label stack on the support platform to obtain multiple scanned images with overlapping areas, and the collected images are directly sent to the straight line detection and image stitching module.

[0030] (3) The images collected by each camera a...

Abstract

The invention discloses a cigarette pack lamination layer number measurement method and device by a multi-camera array. The method comprises the following steps of (1) arranging and adjusting an imaging device; (2) acquiring a cigarette pack lamination layer scanning image, acquiring multiple images of adjacent lamination layer end surfaces with enough overlap regions by the camera array, and transferring the acquired images to a counting module; and (3) carrying out processing such as image correction, maximum narrow-strip direction field linear detection and dotted line dual image splicing on partially-overlapped adjacent images, achieving complete lamination layer end surface image reconstruction, and finally, completing the total measurement of cigarette pack number by vertically transect sampling and counting. The method has the advantages of high measurement accuracy, high instantaneity, wide application range and convenience in operation.

Description

Technical field [0001] The invention mainly relates to the field of post-printing sub-packing and counting in the printing and packaging industry, in particular to a method and device for measuring the number of stacked cigarette labels in a multi-camera array. Background technique [0002] Cigarette labels are packaging boxes for tobacco products, which are high-end printing products. After the cigarette label is printed, it is necessary to accurately count and divide the batch of products. This is not only to control the inventory, but also to achieve the connection with the next process. Traditional mechanical or pneumatic counting devices have risks of damaging paper and forming scratches, so they are less used for cigarette label counting. The method based on machine vision has been widely used due to the advantages of no loss and low error. Among them, there is an urgent need for a real-time quantity detection device for non-destructive, high-stack cigarette labels. Howe...
