Abstract
This paper describes a system for dense depth estimation for multiple images in real-time.
The algorithm runs almost entirely on standard graphics hardware,
leaving the main CPU free for other tasks as image capture, compression and storage during scene capture.
We follow a plain-sweep approach extended by
truncated SSD scores,
shiftable windows
and best camera selection.
We do not need specialized hardware
and exploit the computational power of freely programmable PC graphics hardware.
Dense depth maps are computed with up to 20 fps.
