Description
Technical Field
The present invention relates to the field of block chains, and more particularly, to a block chain lens shape recognition system and a corresponding terminal.
Background
Blockchains are a term of art in information technology. In essence, the system is a shared database, and the data or information stored in the shared database has the characteristics of 'unforgeability', 'whole-course trace', 'traceability', 'public transparency', 'collective maintenance', and the like. Based on the characteristics, the block chain technology lays a solid 'trust' foundation, creates a reliable 'cooperation' mechanism and has wide application prospect.
The blockchain originates from the bit currency, 11.1.2008, and a person who calls the intelligent agent (satoshi nakamoto) lists the bit currency, namely a point-to-point electronic cash system, and explains the architecture concept of the electronic cash system based on the P2P network technology, encryption technology, timestamp technology, blockchain technology and the like, which marks the birth of the bit currency. Two-month later theories step into practice, and a first creation block with the serial number of 0 is born on 1 month and 3 days in 2009. The block with the number 1 appears in 2009 at 1/9, and is connected with the created block with the number 0 to form a chain, which marks the birth of the block chain.
In recent years, the attitude of bitcoin in the world has fallen, but a blockchain technique, which is one of bitcoin underlying techniques, has been increasingly emphasized. In the process of forming the bitcoin, the blocks are storage units one by one, and all communication information of each block node within a certain time is recorded.

Detailed Description
Embodiments of a block chain lens profile recognition system and a corresponding terminal according to the present invention will be described in detail with reference to the accompanying drawings.
The lens is made of transparent materials with one or more curved surfaces, which are made of optical materials such as glass or resin, and the lens is often assembled with a spectacle frame to form spectacles after being polished, so that the spectacles are used for correcting the eyesight of a user and obtaining a clear visual field.
The lens can be mainly classified into a glass lens, a resin lens, a PC lens, etc. according to the material. Resins are hydrocarbon (hydrocarbon) secretions from plants, particularly conifers, that are valued for other specific chemical structures. The resin can be classified into natural resin and synthetic resin, and the resin lens is a lens chemically synthesized by using the resin as a raw material and formed by processing and polishing. The resin lens has obvious advantages, light weight and more comfortable wearing; secondly, the resin lens has strong shock resistance, is not easy to break and is safer; meanwhile, the resin lens also has good light transmission; in addition, the resin lens is easy to reprocess and can meet special requirements, and finally, the resin lens also has good wear resistance due to the innovation and promotion of a coating process, so that the resin lens becomes the mainstream of the lens on the market.
Currently, after a user wearing eyeglasses selects an eyeglass frame and lenses, the lenses are ground to obtain a lens shape and size that matches the various different types of eyeglass frames selected. However, currently, most of the existing methods manually perform the polishing process of the lenses by using a manual polishing method, or manually perform subsequent fine polishing operations after polishing a semi-finished lens product with a fixed size and a large size by using an automatic polishing machine, obviously, the speed of the polishing mechanism of the lenses is slow, and users who need to wear glasses wait for a long time.
