Embodiment Construction
[0022] The embodiments of the present invention will be described in detail below with reference to the schematic structural diagram of the system of the present invention. The described embodiments are only some of the novel embodiments of the present invention, not all complete embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0023] Such as figure 1 As shown, the implementation system of the present invention mainly has three participants, namely publishers, service providers and users, and the content of the information code is divided into two parts, namely static information and dynamic information. The invention enhances the self-adaptability of the information code through the data collection of environmental information such as time and space by built-in sensors. Its main workflow is as follows, you can refer to figure 2 : ...

The invention discloses a software defined space-time extensible information code which uses a machine learning algorithm to smartly match corresponding information content for users by sensing environment characteristic information grabbed by user equipment and the historical data. In the aspect of coding way, a layered coding mechanism is employed. Code blocks with non-uniform resolution and multiple granularities are used to embed information into space, and layered coding of the information code is conducted according to the distance. The information code software of the invention improves the conventional way of obtaining information through code scanning, and the information code can be obtained by combining the environment information and input characters or operation gestures. The method and system have downward compatibility of conventional static QR code technology, no extra hardware cost is spent, and realization is convenient and fast. The method and system are applicable to any equipment and applications using QR codes, such as smart phones, ATMs, flat computers, advertisement display screens, conventional media, and ID verification devices.
Description
technical field [0001] The present invention relates to multiple technical fields such as computer software technology, mobile environment perception technology, machine learning algorithm, two-dimensional code design, generation, identification, etc., and specifically relates to an information layered far-near-scalable algorithm based on mobile environment perception technology and deep learning algorithm. An extended information code design method, and information code recognition software using the method. Background technique [0002] With the rapid development of computer Internet and smart phone mobile terminal network applications, scanning QR codes has become one of the most common ways for mobile device users to obtain information in the physical world. [0003] At present, the two-dimensional code mainly has the following functions: information acquisition, web page jump, advertisement push, mobile e-commerce, anti-counterfeiting traceability, preferential promotio...
