A NEW technology created by Shanghai Jiao Tong University and used to find the Shenzhou-9 spacecraft will be able to help police locate missing persons faster and easier than before.
The broadband communication system developed by the university will work in conjunction with digital image and facial recognition software to help find a missing person.
For example, once a person goes missing, a family member can contact police and provide a photograph. Police will then upload the image to their database. Based on footage from surveillance cameras around the city and facial recognition software, the system would then locate the person's last known whereabouts.
It has other applications.
It was used to help the command center for the Shenzhou-9 space mission locate the capsule and astronauts as they returned to Earth. A wireless broadband ultra-short wave communication system was installed on a helicopter to help search for the returning Shenzhou-9 capsule. It was capable of covering a search area of 60 kilometers. The technology allowed videos of the search process to be transmitted to the command center in Beijing with only a one-second delay.
The video feed helped the command center understand the real-time conditions and make correct decisions as the search team looked for the returning space capsule.
Gui Lin, a researcher at Shanghai Jiao Tong University's School of Electronic Information and Electrical Engineering, said it can also be used in search work after a natural disaster.
The system will be displayed at the China International Industry Fair 2012, which will be held at Shanghai New International Expo Center from November 6 to 10.
There are more than 1,900 sets of surveillance cameras at intersections around the city. Shanghai plans to add about 200 sets of road surveillance cameras annually.
