Expanding our field of view up to 180º

by IT on 23-04-2018
The project ACode180Video aims to expand the limited field of view (FoV) of humans up to 180 degrees. A modular camera setup was built to capture multiple HD images to be compressed and stitched into a single UHD panoramic resolution with 180º FoV. This setup is comprised of 9 HD cameras mounted in a semi-circular arrangement, each one connected to a low cost processor module, which in turn is linked with a central processor unit. The processing modules are responsible for partial encoding of each image while the central one completes the process.

The project investigates efficient image stitching methods to combine images from all cameras with low computational complexity. This includes finding a reduced set of common visual features, match them between adjacent view images, geometric transform and blending.

The expected results include efficient joint coding and stitching algorithms suitable for implementation on low-cost consumer-grade equipment. Hopefully contributing to the development of sophisticated, yet affordable technology for all.

Project ACode180Video was developed under the coordination of Pedro Assunção, from the Multimedia Signal Processing Group of IT in Leiria
