Students are brushing their faces to buy food.
Yesterday, the reporter went to the eleventh middle school cafeteria in Hangzhou for a hot lunch. This canteen is very different from the canteens of other families. When students eat, they don’t brush their faces but brush their faces. In other words, thousands of high school students at the school now rely on their faces to eat.
Each window of the student cafeteria is equipped with a “brushing face†in front of the window, with a camera, which can be operated by touch screen. At first glance, it is similar to a normal tablet computer. As long as the student stands in front of the "brush face" for one second, the identity will be recognized. Then, the dining information such as name, meal card balance and package type will appear on the screen, click “confirmâ€, that is, after the checkout is completed, you will be able to get the fragrant meal handed over by the canteen master.
This is the 3.0 version of the Hangzhou 11th Intelligent Canteen. Previous versions of version 2.0 have been able to complete ordering and payment through mobile phone WeChat, but only need to use the card in the meal taking. The 3.0 version is based on the 2.0 version, which adds the face recognition function. Students only need to queue up to brush their faces, they can certify the meal, and no longer need to bring a card. At the same time, the nutrition report generated according to the daily eating situation of the students is also sent to the parents once a month to become once a week.
Zhang Guanchao, the vice president of the school, said that the reason why the smart canteen was upgraded this semester is because the teachers found that there are a lot of "Little Horses and Big Daha". There are about 50 students who forget to bring a meal card every day, and they directly lose the meal card. The most exaggerated one, lost three rice cards in one semester. Therefore, after the 3.0 version of the Smart Canteen was launched on the line, the high school students said: Since then, the mother no longer has to worry about forgetting to bring the card.
The Smart Canteen 3.0 is actually associated with each student's student ID number and its IC card. Each person's photo is also associated with the student status number. When the camera takes a photo of the student, it will read the photos in the database. This means that the IC card is successfully matched, and the information in the IC card can be called naturally. Therefore, the recharge is still charged to the IC card, but this IC card is already a virtual IC card, it is just a card number and account number.
"I think it's quite convenient to brush your face, and the meal card doesn't need to be taken." Gao Yi, a boy from Xiaoyi, spoke with his classmates and whispered. However, because I just started to try, there are some interesting small situations happening from time to time on the spot.
For example, there was a boy who stood in front of the "brush face" and was not recognized. "Is it because I don't look good, so I don't want to recognize me?" The boy joked that he hadn't laughed at the classmates before, and he was happy. He smiled and immediately jumped out of the dining information on the screen. "It turned out that it was deliberately not confessing me, it was for me to laugh."
The other boy was identified in a second, but the system prompted him to troubleshoot the team. "Oh, I am setting the D package, how to get to the window of the C package, or it is good memory!" The boy quickly moved to the next window.
In order to ensure that the instrument can accurately identify the whole school, when the school enters the photo, it is recommended that students put different POSE and different expressions, such as: serious face, smiling face and slight side face. In this way, whether you are serious or smiling, the front side or the side face, as long as you take a face with the "brush face", you will be recognized.
In addition to changing photos, it is possible to use cartoon avatars in the future - all of them are recorded and recognized, but the cartoon avatar is displayed on the instrument.
The school is prepared to verify the speed and accuracy of the card by brushing the face, and then it will be used for face attendance. Because the class is carried out in high school, the teacher is very vocal about the attendance of the students in the class. Every day, students from different administrative classes face management loopholes if they do not name them. It is a waste of time if they are named one by one. Brushing face attendance and saving time by name means increasing class time.
