Wei Xiaoyong, an associate professor at the School of Computer Science, Sichuan University, said: Some things on the Internet are misinformed, not for roll call at all. . In 21, he set up a four-person team to develop this system for entertainment, and put it into use in Sichuan University in March 211. In fact, the original intention of introducing the classroom is not to examine the attendance of students in class, but because the content of the professional courses he teaches is related to this system and needs to be demonstrated in class. As a result, it was mistaken by netizens as an artifact.
Wei Xiaoyong developed the "attendance system based on face recognition" because he thought it would take a lot of time to count more than 1 names in a class. He took a panoramic picture of the classroom before class, and went back to check all the students' faces with the recognition system. Those who didn't show up were those who didn't come to class. "So my class has a high attendance rate. Moreover, other departments have begun to use the system to check attendance. " Wei Xiaoyong said.
Wei Xiaoyong said that although it only took two or three weeks to develop the "face recognition attendance system", the technical accumulation is a long-term process, and the cost of the server is about 2, yuan to 3, yuan. Later, many businesses and schools contacted him, but Wei Xiaoyong didn't want it to be a tool for compulsory roll call and refused.
"In my opinion, this can't be simply said whether it is good or not. After all, each individual's situation is different. Some junior students really need to be restrained; For senior students, they should be given freedom and should not be forced to call the clock. "
Wei Xiaoyong said that the biggest function of this system is not point-to-point, but to use face recognition technology to analyze interpersonal communication between social individuals. It keeps a record of the individual's location, from which it infers the interpersonal relationship of the object. Wei Xiaoyong said that the equipment still has some problems, and the pure recognition accuracy in the closed space is not high. He has applied for a national invention patent for the equipment, but he has not considered it for marketing for the time being. I refuse to let anyone use it for compulsory roll call, and welcome it for scientific research.
