Embodiment Construction

[0045] see figure 1 As shown, a method for binding a two-dimensional code decoding library and a supporting camera of the present invention, the method specifically includes the following steps:

[0046] Step 1, the camera is connected to a CPU through a Camera interface and an I2C interface, the Camera interface is used to transmit image data, and the I2C interface is used to transmit camera configuration control commands;

[0047] Step 2, the CPU transmits the camera configuration control command through the I2C interface to configure the camera and start the camera, and the CPU receives the image data through the Camera interface;

[0048] Step 3, judge whether the camera is compatible with the two-dimensional decoding library; if not, end the process; if yes, encrypt and sign the image data, and enter step 4;

[0049]Step 4. Verify the image data of the encrypted signature; if the verification is successful, decode the image data and enter step 5; otherwise, return to ste...

Abstract

The invention provides a method for binding a two-dimensional code decoding library and a supporting camera, the method is 1, the camera is connected to a CPU through a Camera interface and an I2C interface; 2, the CPU transmits a camera configuration control command through an I2C interface, and the CPU passes Camera interface receives image data; 3. Judge whether the camera is compatible with the two-dimensional decoding library; otherwise, end, if yes, encrypt and sign the image data, and enter 4; 4. Verify the signature of the image data; If the verification is successful, decode the image data, enter 5, and return 2 if unsuccessful; 5. Obtain the decoding result, feed the result back to the client application, and continue to obtain the next image data for cyclic operation until the decoding is completed All image data. The invention also provides a system for binding a two-dimensional code decoding library and a supporting camera, which realizes a low-cost binding method and improves safety.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method and system for binding a two-dimensional code decoding library and a supporting camera. Background technique [0002] In modern commercial activities, QR codes are widely used, such as product anti-counterfeiting / traceability, advertising push, commodity trading, information transmission and so on. With the vigorous development of the domestic Internet of Things industry, more two-dimensional code technology application solutions have been developed. [0003] The current methods of providing two-dimensional code solutions mainly include: [0004] A) A separate decoding library is provided, but no supporting dedicated camera is provided. The decoding effect and speed of this method cannot be guaranteed, and cannot meet special industrial applications. Moreover, customers do not need to purchase another authorization after purchasing an authorization, and can ...
