From Two Rolling Shutters to One Global Shutter

CVPR 2020oral

Most consumer cameras are equipped with electronic rolling shutter, leading to image distortions when the camera moves during image capture. We explore a surprisingly simple camera configuration that makes it possible to undo the rolling shutter distortion: two cameras mounted to have different roll…

Minimal Rolling Shutter Absolute Pose with Unknown Focal Length and Radial Distortion

ECCV 2020poster

The internal geometry of most modern consumer cameras is not adequately described by the perspective projection. Almost all cameras exhibit some radial lens distortion and are equipped with electronic rolling shutter that induces distortions when the camera moves during the image capture. When focal…

Reconstruction of 3D flight trajectories from ad-hoc camera networks

IROS 2020poster

We present a method to reconstruct the 3D trajectory of an airborne robotic system only from videos recorded with cameras that are unsynchronized, may feature rolling shutter distortion, and whose viewpoints are unknown. Our approach enables robust and accurate outside-in tracking of dynamically fly…

On the Two-View Geometry of Unsynchronized Cameras

CVPR 2017poster

We present new methods of simultaneously estimating camera geometry and time shift from video sequences from multiple unsynchronized cameras. Algorithms for simultaneous computation of a fundamental matrix or a homography with unknown time shift between images are developed. Our methods use minimal…
