Can you buy a subway ticket by saying something to the ticket machine? This scene will become a reality in the Shanghai subway. On December 5th, a number of “black technologies†such as voice ticket purchase, face-to-face pitfall, and intelligent passenger flow analysis debuted in Shanghai. These three technologies are the latest stage results of the Shanghai Metro in August this year. At present, these technologies have completed laboratory testing and entered the prototype development stage, and will be applied to the Shanghai Metro in the future. The Shanghai Metro has a total of 17 lines and 367 stations. When you buy a ticket, you only need to tell the ticket machine the destination, such as “I want to go to the Oriental Pearlâ€. The ticketing opportunity automatically recommends the line and the station to the passengers. The passenger scans the code or brushes the face. You can buy tickets for a total of a few seconds. "The current mainstream far-field speech recognition technology works well in quiet environments such as homes and offices. However, in the noisy environment of public places, the industry has not yet achieved a large-scale commercial level of far-field voice interaction. The voice ticket vending machine is the first product in the industry to achieve precise long-distance voice interaction in a noisy public place environment.†Ai Baba iDST senior artificial intelligence expert Qi Zhijie said that iDST deeply integrates speech signal processing and computer vision technology. Solved the problem of strong noise interference. At present, mainstream voice interactive products on the market need to interact through the "awake words + voice instructions". The voice ticket vending machine can automatically detect the behavior of the passenger approaching and initiate the interaction without the user waking up. It is reported that the Shanghai Metro voice ticketing machine is completely developed independently by iDST, the core team of Alibaba's artificial intelligence. The "next generation human-computer interaction" technology used is one of the first research directions announced by Alibaba Dharma. In addition to the difficulty of buying tickets, forgetting to bring a subway card is often a headache for passengers. In the future, "brushing the face into the station" will solve this problem. It can be found that a new screen has been added to the new inbound gates under development. When the user passes the screen, there is almost no need to stay. The screen relies on Alibaba face recognition technology to complete face recognition and turn on the gate for passengers. by. In the internationally disclosed face comparison evaluation LFW, the accuracy of Alibaba's face recognition algorithm exceeds 99.5%; in the case of identity authentication 1:1 comparison scenario, the false positive rate is 0.1%, the measured accuracy is greater than 99%. 1:3000 identification scene, on-site measured recognition rate >95%. The intelligent passenger flow analysis technology is based on video recognition, data analysis machine learning and Alibaba Cloud's data visualization technology. It replaces the naked eye, observes the passenger flow speed, density, congestion index, etc., and combines subway train operation information and external weather information data. Forecasting future traffic, helping subway staff to conduct passenger flow diversion, emergency dispatch, and danger prevention to ensure passenger safety. Alibaba senior algorithm expert Wang Lei introduced that the difficulty of this technology is how to use the existing standard-definition camera to make high-accuracy human body recognition in the subway environment with unstable lighting conditions. At the same time, it is necessary to remove multiple occurrences of the same passenger in multiple cameras, and how to make accurate ultra-short-time passenger flow prediction. More than a month ago, Shanghai Metro officially launched the mobile phone app "Metro Metropolis", and began to scan the code to enter the station. Shanghai Metro plans to promote the scanning code in the city's 17 rail transit lines early next year. Passengers only need to bind Alipay in the “Metro Metropolis†app, you can sweep the bus code to enter the station, and then deduct the fare when you leave the station, no need to exchange change and queue to buy tickets. Zhang Tinghua, head of Alibaba Cloud Shanghai Branch, said that in the future, the two sides will continue to explore the introduction of cloud computing, big data, artificial intelligence, and Internet of Things technologies into the Shanghai Metro.
