Virtual Keyframes for Environment Map Capturing


Sehwan Kim, Christopher Coffin and Tobias Hollerer

The acquisition of surround-view panoramas using a single hand-held or head-worn camera relies on robust real-time camera orientation tracking and relocalization. We present robust methodology for camera orientation relocalization, using virtual keyframes for online environment map construction. Instead of solely using real keyframes from incoming video, our approach employs virtual keyframes which are distributed strategically within completed portions of an environment map.
