Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] In the embodiment of the present invention, by collecting an image including the pattern to be tested, and then performing image standardization processing on the collected image, a standardized image is obtained, and by comparing the standardized image with a pre-stored reference image, the pattern to be tested can be achieved. purpose of testing.

[0032] figure 1 The implementation flow of the pattern detection method provided by the embodiment of the present invention is shown, and the details are as follows:

[0033] In step S101, an image including a pattern to be tested is collected...

Abstract

The invention provides a pattern detection method, a device, equipment and a system, which are applicable to the field of detection. The method comprises the following steps: collecting images comprising patterns to be detected; carrying out standardization treatment on the collected images to obtain standardized images; and comparing the standardized images with the pre-stored reference images to obtain image detection results. The standardization treatment comprises the gray scale binaryzation treatment on the collected images and the edge tracking treatment on the images after the binaryzation treatment. The embodiment of the invention avoids various defects caused by adopting a visual measurement method to detect the patterns, reduces the pattern detection cost and the incorrect judging rate, and improves the pattern detection efficiency and the consistency.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a pattern detection method, device, equipment and system. Background technique [0002] With the continuous development and growth of the electronics industry, the production scale of electronic products is also increasing. Generally, in the production process of electronic products, a certain pattern will be pasted on the electronic products as the label of the electronic product, such as laser engraving labels. etc. for user identification. In the production process of electronic products, in order to keep the patterns pasted on electronic products the same, it is necessary to detect these patterns pasted on electronic products. How to quickly and accurately detect the patterns pasted on electronic products has also become an a problem in the process. [0003] In the current production process of electronic products, the detection of such patterns generally adopts the method...
