Automatic camera-screen localization

Abstract

Knowing the location of the TV screen with respect to a camera it is important for many applications. This work addresses this problem in a configuration where there are people looking at the TV and a RGB-D camera facing them, located near the TV screen. We propose a method to automatically estimate the screen location and camera rotation using only people’s head pose obtained from a Face Tracking analysis on the RGB-D video. We validated these algorithms on a dataset with groundtruth and obtained very promising results.
