　　自動(dòng)售酒機(jī)如何識(shí)別你拿的東西？

How does the vending machine recognize what you are holding?

　　1. 靜識(shí)態(tài)別：在每一層貨上架都安裝一個(gè)像攝頭，俯視這一的層商品，在你關(guān)開門的時(shí)候，它分會(huì)別拍下兩照張片，服務(wù)器比商對(duì)品信息，完結(jié)成算。但每都層要安裝攝像頭，不僅硬成件本高，而且每層得還留出一定高度。

1. Quiet state: Install an image camera head on each shelf of goods, looking down at this layer of goods. When you close the door, it will take two separate photos, and the server will compare the product information to complete the calculation. But each layer needs to be equipped with cameras, which not only have high hardware costs, but also leave a certain height for each layer.

　　2. 視覺態(tài)動(dòng)識(shí)別：攝像頭并裝不在貨架上，而是裝在售貨的機(jī)，在你拿取品商時(shí)，它拍會(huì)下一小段視頻傳上到服務(wù)器，服器務(wù)會(huì)通算過法識(shí)別圖出像中的商品信息，然后再結(jié)做算。

2. Visual motion recognition: The camera is not installed on the shelf, but on the top layer of the vending machine. When you pick up the product, it will capture a short video and upload it to the server. The server will use algorithms to identify the product information in the image, and then perform the calculation.

　　3. 重力感應(yīng)識(shí)別：每層都放個(gè)一重力感應(yīng)器，拿商完品后，它會(huì)根重?fù)?jù)量變化識(shí)別商品，完成結(jié)算。

3. Gravity sensor recognition: Each layer is equipped with a gravity sensor. After receiving the product, it will identify the product based on changes in weight and complete the settlement

　　4.射頻識(shí)別超高識(shí)頻別：用這上種技術(shù)的售貨機(jī)，商品上貼會(huì)一張射頻識(shí)別標(biāo)簽，當(dāng)你把拿它出來后，標(biāo)就簽會(huì)穿過售機(jī)貨內(nèi)部的磁場(chǎng)，產(chǎn)生應(yīng)感電流，并向外發(fā)射定特頻率的線無電信號(hào)。售貨機(jī)中的閱器讀接收對(duì)到應(yīng)信號(hào)，就完能成結(jié)算，扣掉的你錢。

4. RFID ultra-high frequency identification: vending machines using this technology will have an RFID tag attached to the product. When you take it out, the tag will pass through the magnetic field inside the vending machine, generate an induced current, and emit a fixed frequency line with no electrical signal to the outside. Once the reader in the vending machine receives the corresponding signal, it can complete the settlement and deduct your money.
