Abstract:
With the recent availability of large collections of images and videos
through websites like Flickr and You Tube researchers have started to
use the data for 3D reconstruction. The talk will discuss our recent
approaches to tackle the challenges in this research area like our
real-time scene reconstruction system, efficient 3D reconstruction form
large-scale image collections and our recently proposed location
recognition from images using local geometry. Our real-time scene
reconstruction system uses the video of a moving (un-)calibrated camera.
To enable image based path intersection detection we developed an image
based location recognition, which will be introduced during the talk. It
is based on the viewpoint invariant patches (VIP). The location
recognition combines image based scene recognition with local geometry
to enable a drift free construction from several hundred thousands of
images. |
