High Frequency 3D Reconstruction from Unsynchronized Multiple Cameras

Abstract

Stereo reconstruction generally requires image correspondence such as point and line correspondences in multiple images. Cameras need to be synchronized to obtain corresponding points of time-varying shapes. However, the image information obtained from synchronized multiple cameras is redundant, and has limitations with resolution. In this paper, we show that by using a set of unsynchronized cameras instead of synchronized one, we can obtain much more information on 3D motions, and can reconstruct higher frequency 3D motions than that with the standard synchronized cameras. As a result, we can attain super resolution 3D reconstruction from unsynchronized cameras. The efficiency of the proposed method is tested by using real image sequences.

Triangulation

“…3D reconstruction from camera images based on triangulation has been considered under various situations, such as triangulation from uncalibrated cameras [8,9], triangulation from unsynchronized cameras [10], triangulation from rolling shutter cameras [11], and triangulation from a huge amount of cameras [3].…”
