What can you do in six seconds? Watching a segment of President Obama's life in the White House is six seconds; In six seconds, Reid Wiseman, an astronaut on the International Space Station, showed the unsetting sun as he saw it during a 90-minute orbit around the space station. What about transportation? What can you do in six seconds? What can you change?
"As long as in Henan Province, in a complex weather environment, it only takes six seconds to complete the cause analysis of the accident in one minute from the time when the highway accident happens and the manager has a clear understanding of the situation on the scene, the accuracy rate is far higher than the national standard." Dr. Zhao Ying from Tsinghua Tongfang said confidently at the final of 2017 China "Cloud Guizhou" smart transportation Big Data Application Innovation Competition.
Tsinghua Tongfang artificial Intelligence "Huiyan Da" is a joint project of Henan Provincial Transportation and Communication Center and Tsinghua Tongfang. Different from most projects that remain at the concept level, "Huiyan Da", as a monitoring platform for abnormal highway events using video data, has taken the lead in realizing real-time monitoring of the whole road network and all scenes in Henan Province. The deep learning technology and entropy mutation model were used to monitor and predict the running situation of each road network, and the abnormal events were accurately identified and reported in real time. Even in extreme environments and blind areas of highway cameras, real-time monitoring of road operation situation can be achieved through adaptive scene switching target recognition technology and indirect prediction model of road network operation. Abnormal events can be reflected in seconds through deep mining and deep learning of video signals, and cause analysis can be completed within one minute, with an accuracy of more than 98%.
As He Junhong, chief scientist of Huawei Traffic Brain, said when commenting on Tsinghua Tongfang's "Huiyan" at the competition site, "Tsinghua Tongfang's" Huiyan "not only saves time, but saves lives. The sooner the rescue arrives at the scene, the more likely the wounded are to survive."
With its technical strength and practical experience, Tsinghua Tongfang's "Vision Vision" has proved that six seconds is not only about watching time, but also about reality. It will save a person's life and change the fate of a family.
Whether it is 6 seconds or 98%, "data" seems to carry a cold sense of alienation, but Tsinghua Tongfang "Huiyan Da" proves its top level in the field of smart transportation big data application with strength. After 150 days and five rematches in Beijing, Shenzhen and Guiyang, Tsinghua Tongfang AI "Huiyan Da" won the third prize in this competition with 535 projects from home and abroad. Academician Ni Guangnan expressed his hope to promote Tongfang AI Insight as a national standard when commenting on the competition site.
It is understood that the competition is the first national transportation industry with the largest scale, the most extensive range, the most specifications
High big data application innovation competition. It aims to make use of more than 4,000 national and provincial government and enterprise data sets to break the ice of thinking and point to the pain points of traffic by being problem-oriented, supported by data and based on technology.
Tsinghua Tongfang will always uphold the enterprise purpose of science and technology to serve the society, with innovative scientific research technology to serve the national strategy of "transportation power".
