Amazon unmanned convenience store officially opened, and analyzed the "technical secrets" of unmanned supermarkets

Amazon’s five-year unmanned convenience store officially opened.

According to Recode, after a 14-month trial run, Amazon Go, the unmanned convenience store on the first floor of the new Amazon headquarters in Seattle, will be open to the public on January 22, the first unmanned retail store in Amazon. Amazon promises that consumers can “redo without queuing, no checkout, no cashier”, thus reshaping the physical shopping experience.

The store is about 167 square meters in size, and consumers need to scan the Amazon Go app with their mobile phone when they enter. There are a lot of black cameras in the store, and there are weight sensors on the shelves, which can help Amazon detect who is taking the goods. The virtual shopping cart is updated when the consumer removes the item from the shelf, and when the customer leaves the store, Amazon automatically debits the customer's account and then sends the bill. If the consumer puts the item back on the shelf, Amazon will remove the item from its virtual shopping cart. This technology is also called "Just Walk Out" by Amazon, mainly using computer vision, deep learning and sensor fusion technology.

Although the application of this technology can save the "cash register" step, there are still people working in the store. Recode reports that there will be a welcome clerk at the door of the unmanned convenience store, and another employee will check the consumer's ID card in the wine and beer area; in the kitchen, there are at least six staff members.

It is worth noting that in June 2017, Amazon announced the acquisition of Whole Foods for $13.7 billion. At that time, the outside world speculated that the end of the era of customer check-out in the store, set off the robot revolution. But according to Dilip Kumar, chief technology officer of Amazon, Amazon has no plans to apply this technology to other physical environments. Amazon only set up a special area for Whole Foods in the store, such as the 365 Everyday Value brand of biscuits and nuts from Whole Foods.

Kumar also said that five years ago, he was thinking about what Amazon can do in terms of "convenience." Many survey results at the time showed that consumers "do not like to queue." To this end, Amazon has begun to develop related technologies.

On December 6, 2016, Amazon Go opened a test for Amazon employees and is expected to be available to the public in early 2017. But in March 2017, the Wall Street Journal said that because at the same time, the number of customers that can be handled by new stores cannot exceed 20, Amazon's unmanned convenience stores can only be postponed.

In China, Ali and JD's unmanned convenience stores have already taken the lead in opening. On July 8, 2017, at the second Taobao Creation Festival, Alibaba's long-awaited “unmanned convenience store” officially appeared to the public, and the official said it was “Taobao member store”. In October of the same year, the first unmanned supermarket and unmanned convenience store in Jingdong was unveiled at the Jingdong Headquarters Building in the Beijing Economic and Technological Development Zone.

It seems that this has suddenly become a vent. However, "the supermarket still dares to engage in no one. Isn't it not afraid to 'shun the sheep'?" In fact, there is no need to worry, because the technology has already solved most of the "possible moral problems" of unmanned supermarkets. how did you do that? Xiao Mu will come to analyze the three popular solutions in the market today - the "technical secrets" of unmanned supermarkets. Which kind of prospect do you have to look at?

1 Amazon's artificial intelligence solution

Through artificial intelligence such as convolutional neural networks, machine vision, deep learning, biometrics and other cutting-edge technologies, an artificial intelligence retail system is created to provide intelligent upgrades for traditional retailers with no one or fewer people. For example, when a user enters the store, he will enter the palm capillary data by registering once, and use our algorithm to give each customer a unique lifetime ID, which is in line with the behavior detection algorithm of the posture, which is an important way to solve multi-person tracking. A 38-layer convolutional neural network is used on the identification of goods. The 50-layer convolutional neural network is used to identify postures and gestures, and the neurons in each layer are optimized to construct a brain with certain IQ. Eyes, plus the space-modeling partitioning mechanism, complete the "sweeping hands into the store, take it and leave."

2 Ma Yun Dad's Internet + genre

The user uses the QR code to scan the code to open the door, scan the code to settle, and the product can scan the code and trace the source. The program can identify all categories, but lacks verification, supervision, and users need to download the app to complete the payment, but it is not practical to ask consumers to download the app every time they enter an unattended convenience store. At present, Ali's unmanned convenience store "Amoy coffee mainly uses this scheme (superimposed RFID).

3 Bingo Box and RT-Mart's Internet of Things School

Identification and settlement are realized by using RFID (radio frequency identification) sensors, sensors, and scanning code guns. RFID technology was born in 1930. It was widely used during the Second World War. It is very mature now. The disadvantage is that the cost is too high. Only one label costs about 1 yuan. In addition, there are many RFID non-affinitive media, which can not be applied to the packaging of metal, liquid and internal aluminum foil. In case of liquid, the mis-reading is serious due to absorbing, and the RFID is very easy to be shielded. The label is sticky and easy to be torn. Size and sensing distance are not easy to coordinate. It is reported that the recently-funded Binguo Box and the RT-Meng Box are all used in this program.

Android Tablet

Android is an open source mobile operating system based on Linux platform released by Google at the end of 2007, and then improved for use in netbooks and MIDs. The platform consists of operating system, user interface and application software, and is claimed to be the first truly open and complete mobile software for mobile terminals.

To put it simply, the Android system is actually a very open system. It can not only realize the functions of the most commonly used notebook computers, but also realize various directional operations like mobile phones. Moreover, it is specially designed for mobile phones. The operating system developed for equipment has advantages in system resource consumption and human-computer interaction design. It is an operating system that combines traditional and advanced advantages.
