Embodiment Construction

[0022] 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.

[0023] see figure 1 , the present invention provides an ultramicrocode identification method, combining figure 2 and image 3 It includes the following steps:

[0024] A. First, irradiate the measured object with a blue light source;

[0025] B. Magnify the measured object by 6 times and configure the size of the QR code;

[0026] C. The zoom camera module is adopted, and the lens of the module adopts 3P~5P blue-coated film;

[0027] D. Configure the camera driving algorithm, calibrate the three-dimensional coordinates according to the two-dimensional code of the measured object, fix the zoom...

Abstract

The invention provides an ultramicro code recognition method. The ultramicro code recognition method comprises the following steps: A, irradiating a detected object with a blue light source; B, amplifying the measured object by 6 times, and configuring the size of the two-dimensional code; C, adopting a zoom camera module, wherein a lens of the module adopts a 3P-5P blue-plated film; D, configuring a camera driving algorithm, calibrating a three-dimensional coordinate according to the two-dimensional code of the measured object, and fixedly amplifying and adjusting the height of a bracket rod of a camera module on a z axis; and E, enabling the platform for placing the measured object to be adjusted in the x-axis direction and the y-axis direction. Therefore, the laser dot matrix code making cost can be saved, and only one identification code module and one light source are needed.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting identification, in particular to an ultramicrocode identification method. Background technique [0002] For a long time, counterfeit and shoddy products have disturbed the market order and seriously damaged the legitimate interests of enterprises and consumers. Most enterprises have to seek various anti-counterfeiting technologies for product protection. Among many practical anti-counterfeiting technologies, two-dimensional codes are popular because of their convenience in reading. It is widely used in querying entrances, and it has become common to scan and read QR codes through mobile phones and log in to the Internet to query relevant information to verify the authenticity of products. Since QR codes usually appear in clear codes to be read by mobile phones, QR codes themselves are easy to be copied. Its anti-counterfeiting effect is greatly reduced. [0003] In summary, there ar...
