The two-dimensional Code has various types, such as a QR Code two-dimensional Code, a Data Matrix two-dimensional Code and the like are common, the two-dimensional Code is a bar Code which is expanded to another dimension on the basis of a one-dimensional bar Code and has readability, binary Data is represented by a black-and-white rectangular pattern, and information contained in the binary Data can be acquired after the binary Data is scanned by equipment. The width of a one-dimensional barcode carries data, while its length carries no data. The length and width of the two-dimensional bar code are both recorded with data. Compared with the one-dimensional bar code, the two-dimensional bar code has a positioning point and a fault-tolerant mechanism. The fault-tolerant mechanism can correctly restore the information on the bar code even if all the bar codes are not recognized or the bar codes are stained. Specifically, referring to fig. 2, the rule of the whole two-dimensional code may be understood as a defining mechanism of a symbol, and may be specifically divided into two parts, namely a functional graphic region and a coding region format. The functional pattern area also comprises a blank area, a position detection pattern separator, a positioning pattern and a correction pattern; the format of the coding area comprises format information, version information, data and error correction numbers.

Specifically, the electron microscope is fixed right above the two-dimensional code through a special support, and software related to the device for automatically scanning the two-dimensional code by the electron digital microscope is compiled on the basis of a VS2015 programming interface, and calls a halcon library file to perform graphic processing and decoding. Because my department's two-dimensional code is printed on the module, and the two-dimensional code size is smaller, so the electron magnifying glass of corresponding magnification according to the size selection of two-dimensional code before decoding, read the two-dimensional code picture after the amplification from the electron magnifying glass then the preliminary treatment, reinforcing figure contrast (scale _ image), sharpening image (emphasze), make the two-dimensional code picture look more clear, improve recognition speed and efficiency.

Specifically, if the two-dimensional code image is still difficult to decode or the decoding rate is not high after the two-dimensional code image is preprocessed, the decoding capability can be further improved by the following measures, and if the whole image has too much information, the two-dimensional code image can be deducted (reduced domain, setprint, that is, the two-dimensional code image to be processed is obtained by separately extracting the clarified two-dimensional code image described in the foregoing embodiment), so that the decoding difficulty can be reduced, and the decoding time can also be reduced; the deducted two-dimensional code image can be seen in fig. 3. In fig. 3, an area surrounded by a box 301 is a deducted two-dimensional code image. In the halcon decoding process, firstly, a two-dimensional code template needs to be created, decoding parameters are set, then decoding is carried out according to the decoding parameters, and finally, a template recovery memory is cleared; it should be noted that, if the decoding is unsuccessful, the preprocessing is returned to the two-dimensional code image. And then, the identified two-dimensional code information is converted into an identifiable two-dimensional code through coding, the identifiable two-dimensional code information is stored in a clipboard, and the identifiable two-dimensional code information is transmitted to test software for testing through clipboard communication, so that the universality of the system can be improved through the clipboard communication.
