Uchchatar Avishkar Yojana: Wide Area Field of View CMOS Image Sensors for Aerial Surveillance for Defence Applications

What are WFOV cameras?

Wide Field of View Camera Field of view refers to the area that the camera can capture. It is also known as the viewing angle of camera. Thus Wide Field of View (WFOV) cameras refer to the cameras which can cover a large region compared to the conventional cameras. These cameras can locate multiple objects in the region and provide the data to processor for analysis in one go. These attributes makes WFOV cameras one of the preferred choice for surveillance specific applications.


  • Remote Sensing
  • Persistent Surveillance of wide areas
  • Environment monitoring
  • Medical Imaging

Researchers at IIT Delhi have collaborated with industry to design large format cameras for better aerial surveillance.

Aerial surveillance systems have been long used for video surveillance for defence and homeland security.

Automated aerial surveillance can be used for natural resource or environment mapping and monitoring besides applications involving homeland security like border patrol, tactical planning etc. The need to gather intelligence has been a major factor in the development of automated aerial surveillance systems around the world.

Modern surveillance requires persistence to extract intelligence information for which wide field of view with a large area sensor is required. These large area sensors should also maintain situational awareness through high resolution and high frame rate. "The goal of the project is to come up with a better, in-depth understanding and design of large format cameras for wide field of view imaging in deep sub-micron CMOS technology for applications like aerial surveillance in defence. Wide-area surveillance allows monitoring the activity over a large area using only a single camera system which is very beneficial for surveillance, Mukul Sarkar Principal Investigator said.

Besides military application, wide-area surveillance can also be used for emergency response coordination, monitoring restricted areas for movement, monitor crowd and traffic flow, fast wide-area damage assessment; detect movement over broad areas for potential survivors etc. Further wide-area field of view cameras can also be used in space and medical imaging applications.

This project will develop large area sensors for aerial surveillance embedded with some intelligent image processing algorithms for tracking in real time over a wide area of 10 km x 10 km with a resolution of 1 m.

“The challenge is to provide wide field of view situation awareness and multiple narrow fields of view for tracking objects of interests. Real time processing like event detection, target identifications which helps in reducing the data transmission rate will be actively used in future surveillance systems and thus these needs to be incorporated together with the sensor. On the sensor front the challenge is to improve the accuracy, resolution, timeliness and improving processing speed of the data captured.
