نظام الرؤية الثلاثية الأبعاد لنفق طريق Xiangya

The tunnel uses radar video integrated devices to sense traffic flow, vehicles information. The point is to show real time traffic scenario through a fusion algorithm and to generate tunnel holographic traffic data within the coverage of the installed devices. The radar and video fusion is realized, the general overall monitoring is carried out, the traffic element data is accurately collected, the data quality and safety is improved, the traffic events are actively reported in real time, the holographic monitoring and early warning of suspicious vehicles are carried out, and the live channel are superimposed to open up for emergency rescue. The overall digital technology is applied to enhance the visualization and intelligence of tunnel operations.
