Problems solved by technology

[0004] The above-mentioned labeling quality inspection technology has the following defects: Visual inspection is a monotonous and repetitive work. After working continuously for a period of time, inspectors will experience visual fatigue and decreased concentration, resulting in missed inspections and false inspections.
Therefore, this method has the disadvantages of strong subjectivity, high misjudgment rate and low detection efficiency.

Embodiment 1

[0023] see figure 1 , is a flow chart of a labeling quality detection method provided in Embodiment 1 of the present invention. The method in the embodiment of the present invention can be executed by a labeling quality inspection device implemented by hardware and / or software, and the implementation device is typically configured in a server capable of image processing services.

[0024] Such as figure 1 As shown, the method includes:

[0025] Step 110, obtaining the label image of the label to be detected;

[0026] Specifically, in this step, the label image of the label to be detected at the exit of the labeling machine can be taken by the camera device. The imaging device preferably adopts a CCD (Charge-coupled Device, Charge-Coupled Device) camera, which has the advantages of high sensitivity, anti-glare, small distortion, small size, long life and anti-vibration.

[0027] Among them, the labeling machine is a device that sticks labels (paper or metal foil, etc.) on p...

[0051] see figure 2 , is a flow chart of a labeling quality detection method provided in Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment provides an optimal solution for matching the grayscale feature with the grayscale feature of the corresponding feature point of the standard label image, and determining whether the label to be detected is qualified according to the matching result. The method includes:

[0052] Step 210, acquiring the label image of the label to be detected;

[0053] Step 220, perform image preprocessing on the label image, the image preprocessing at least includes: grayscale processing;

[0054] Step 230, acquiring the grayscale feature of the feature point of the pre-processed label image at the set position;

[0055] Step 240, judging whether the grayscale feature satisfies the qualified range of the grayscale feature of the corresponding feature point of the standard label image, if yes, execut...

Embodiment 3

[0064] see image 3 , is a schematic structural diagram of a labeling quality detection device provided in Embodiment 3 of the present invention. The device includes: an image acquisition module 310 , an image preprocessing module 320 , a grayscale feature acquisition module 330 and a detection module 340 .

[0065] Wherein, the image acquisition module 310 is used to obtain the label image of the label to be detected; the image preprocessing module 320 is used to perform image preprocessing on the label image, and the image preprocessing includes at least: grayscale processing; grayscale feature acquisition module 330 is used to obtain the grayscale feature of the feature point at the set position of the label image after image preprocessing; the detection module 340 is used to match the grayscale feature with the grayscale feature of the corresponding feature point of the standard label image, Determine whether the label to be detected is qualified according to the matching...

Abstract

The embodiment of the invention provides a labeling quality detecting method and device. The method comprises the following steps: acquiring a label image of a label to be detected; carrying out image pre-processing to the label image, wherein the image pre-processing at least comprises grayness processing; acquiring gray features of a feature point, in a set position, of the label image processed through image pre-processing; matching the gray features with the gray features of a corresponding feature point of a standard label image, and determining whether the label to be detected is qualified or not according to matching results. According to the scheme, manual visual detection is replaced by the acquisition of the gray features and the matching of the gray features, defects of strong subjectivity, high misjudgment ratio, low detection efficiency and the like of manual visual detection can be overcome, the detection precision to the labeling quality is improved, and the detection efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to detection technologies, and in particular to a labeling quality detection method and device. Background technique [0002] The labeling machine is a device that sticks labels (paper or metal foil, etc.) on packaging containers with adhesives. Labeling machines are an integral part of modern packaging. However, during the labeling process of the labeling machine, the labeling quality may be affected by the labeling machine itself or other external factors, such as label quality or environmental factors, so the application of labeling quality inspection technology was born. [0003] The existing labeling quality inspection technology is generally completed through manual visual inspection, that is, the inspectors of the product export of the labeling machine use manual visual inspection to detect whether the label attached by the labeling machine on the product is qualified, so that To achieve the purp...
