Problems solved by technology

However, in the production process, because the marking surface of the article, such as the marking surface of the tile to be recognized, is often polluted by wax water, wax powder, machine oil and other pollutants on the production line, under visible light, these pollutants are different from the Markers are sometimes difficult to distinguish, or are contaminated by pollutants, and may not be recognized or recognized incorrectly during machine recognition, resulting in a low recognition rate and causing wrong grading or classification

Embodiment 1

[0040] The marker is in the form of a crayon, and the composition of the crayon is as follows:

[0041] The carrier is paraffin: 90 parts by weight;

[0042] The excited luminescent substance is ultraviolet fluorescent powder: 1 part by weight;

[0043] Toner: 1 part by weight.

[0044] Such as Figure 4 As shown in , the ceramic tile is selected as the identified item, and the steps of item identification are as follows:

[0045] Marking step: use the above crayon on the surface of the tile to mark;

[0046] Irradiation steps: place the tiles in a shooting device with an ultraviolet lamp, a camera and a shooting box, and keep the detection area isolated from light and relatively dark;

[0047] Shooting steps: irradiate the crayon marks with ultraviolet light, and take pictures with the camera; in a dark environment, only the crayon marks stimulated by light can be photographed by the camera, and other background objects on the tiles, such as pollutants, because there is n...

Embodiment 2

[0051] The marker is in the form of chalk, and the composition of the chalk is as follows:

[0052] The carrier is gypsum: 80 parts by weight;

[0053] The excited luminescent substance is infrared phosphor: 50 parts by weight;

[0054] Toner: 1 part by weight.

[0055] Such as Figure 4 As shown in , the ceramic tile is selected as the identified item, and the steps of item identification are as follows:

[0056] Marking step: use the above-mentioned chalk on the surface of the tile to mark;

[0057] Irradiation steps: place the tiles in a shooting device with an infrared lamp, a camera and a shooting box, and keep the detection area isolated from light and relatively dark;

[0058] Shooting steps: irradiate the chalk mark with an infrared lamp, and take a picture with the camera; in a dark environment, only the chalk writing that is stimulated to light can be photographed by the camera, and other background objects on the tile, such as pollutants, because there is no Th...

Embodiment 3

[0062] The marker is in the form of a pencil, and the composition of the ink is as follows:

[0063] The carrier is graphite: 60 parts by weight;

[0064] The excited luminescent substance is ultraviolet fluorescent powder: 30 parts by weight;

[0065] Toner: 10 parts by weight.

[0066] Such as Figure 4 As shown in , the ceramic tile is selected as the identified item, and the steps of item identification are as follows:

[0067] Marking step: use the above-mentioned pencil to mark on the surface of the tile;

[0068] Irradiation steps: place the tiles in a shooting device with an ultraviolet lamp and a camera, and the shooting device is set with an open mouth and is not protected from light;

[0069] Shooting steps: irradiate the pencil marks with ultraviolet light, and take pictures with the camera; in the open environment, the pencil marks with stimulated light characteristics can also be photographed by the camera, while other background objects on the tiles, such as...

Abstract

The invention provides a goods identification device. The device comprises a photo-shooting, an image identification unit and an invisible light source, wherein the invisible light source emits an invisible light, and irradiates goods of which the surface is marked by a marker; the photo-shooting unit is used for shooting the item irradiated by the invisible light to acquire an image; the image identification unit is used for identifying the marker on the goods surface based on the acquired image; and the marker contains an excited illuminant excited by the invisible light. According to the goods identification device, the excited market under a matched wavelength is identified by adopting the invisible light source, all background objects except non-marked objects can be filtered, fault grading or classification identified and sorted under artificial or visible light condition can be overcome, and the accuracy of visual identity can be greatly improved.

Description

technical field [0001] The invention belongs to the field of item identification, and in particular relates to an item identification device. Background technique [0002] In the classification and sorting of items, in order to distinguish the characteristics of the items, such as: the quality, color, size and weight of the items, it is usually necessary to classify or classify the items, and then manually mark the different levels or Category items are differentiated and grouped. [0003] For example, in the ceramic industry, the large-scale application of large-scale tile picking lines has greatly reduced the labor intensity of brick pickers moving bricks. The process still needs to rely on manual judgment. This work requires workers to concentrate for a long time. If they are slightly distracted, it is easy to make identification mark errors, which will affect the grading and classification of tiles. When customers buy and use tiles, the user experience is poor. Especi...
