Abstract

Route panorama (RP) has become an image medium to archive and visualize cityscapes along streets. Collecting data from a sampling line of a video camera mounted on a moving vehicle, the route panorama may suffer from the vehicle shaking and varying speeds due to uneven roads and busy traffic respectively. These may jitter the route panorama and change object widths. To produce a high quality route panorama, we extract spatial-temporal information in the video volume and rectify the route panorama. In this paper, we propose two condensed image slices to record traces of horizontal and vertical scenes during the vehicle motion. Instead of matching video frames that requires cost computation and large storage, we track the feature traces in the condensed image slices to remove jitter and adjust the local length of route panoramas. The method is effective and efficient in acquiring and rectifying long distance route panoramas.
