Context enhanced networked services by fusing mobile vision and location technologies


The ViewNet project will develop technology to support enhanced coordination and cooperation between operational teams in the emergency services and the police.

Where operatives are and the hazards around them is crucial knowledge for Commanders to ensure that a safe yet high tempo operation can be achieved. Using TETRA or a secure wireless network, users will be able to localise themselves and map their environment Indoors, in 3D and in real time.

Distributed localisation of users and mapping of difficult environments will enable teams of operatives to search and map an area rapidly and in full coordination with each other and with a control centre.

Sensing will be based on fusing absolute positioning systems - Global Positioning System and Ultra Wide Band with relative localisation and mapping from on-body or hand-held vision and inertial sensors.

The ViewNet architecture has been designed to enable operatives with different communications systems to communicate with each other enabling the system to seamlessly pass data around the ViewNet user network. This would enable operatives to use TETRA radios, Mobile Phones and WiFi.


The project partners have planned to develop a demonstrator system based on TETRA Radios and WiFi on an open platform that will enable the integration of future wireless technologies.

The core areas are:

  • The network architecture to allow multiple users and different communication methods
  • Vision based localisation and mapping to give estimates of position and orientation
  • On-body hardware development
  • Fusion of absolute and relative positioning
