In this talk I shall first introduce Deutsche Telekom Labs and the various aspects of vision, imaging and other ongoing research at the Labs. One particular project is Free Viewpoint TV i.e. TV where you choose your own viewpoint or viewing perspective in real time. A Major problem with using a network of cameras especially over large areas such as in stadiums is synchronization. Unsynchronized cameras cannot be used in any form for novel view synthesis, neither via image based rendering nor 3D reconstruction approaches. In this talk I shall present our ongoing work towards simple and accurate camera network calibration even when the cameras are unsynchronized and run at differing frame rates.

We present a simple linear model for asynchronization and using tracked points in video sequences automatically estimate the synchronization parameters and thereafter accomplish complete camera network calibration including intrinsic and extrinsic parameters. Experiments with simulations as well as real video sequences will be presented. Finally next steps and challenges within the FVTV project will be discussed.
