Cloud computing boosts traffic congestion

Recently, the second China Cloud computing user Congress nationwide roving seminar held in Nanjing, a number of industry experts to explore the cloud and large data based on urban management. Reporter learned from the meeting, Nanjing in the traffic management, urban security and other fields have with cloud computing and large data depth integration, intelligence level is located in the forefront of the country.

"The current city-wide traffic supervision, security surveillance camera generated video data stream all concentrated in the wisdom of the Nanjing Data Center." "China Cloud computing Experts Advisory Committee Secretary General Peng told reporters, the use of cloud computing technology, can achieve accurate statistics of the number of traffic," in addition, through the traffic camera real-time capture and analysis of video images, in the city of the terminal screen, can calculate the length of the lane in real time, help to judge the smooth flow of urban traffic road , find the congested roads in the city in time, and carry out traffic navigation and corresponding processing. ”

Monitor video image clarity is low, can not realize face recognition how to do? Through the massive data cloud analysis, the city in the field of urban security has a video DNA retrieval technology. Peng introduces that the technique can be used to model the walking attitude of the video screen, and to extract the continuous walking attitude, and finally form a dynamic behavior DNA sample. In the sample library, the behavioral DNA of specific characters is compared, so that real-time and fast video DNA retrieval is realized.
