ABSTRACT
Most modern camera designs based on CMOS sensors do not have a global, but a rolling shutter that exposes the lines of the sensor at different times. This leads to distortions under camera or object motion and affects computer vision techniques. This article introduces the use of a linear velocity model for camera motion and estimates these additional parameters in a bundle adjustment. In experiments on synthetic and real image sequences we demonstrate how effects caused by a rolling shutter video camera can be compensated by the velocity estimation.

Self-calibration of omnidirectional multi-cameras including synchronization and rolling shutter

Rolling Shutter Stereo
ICCV '13: Proceedings of the 2013 IEEE International Conference on Computer VisionA huge fraction of cameras used nowadays is based on CMOS sensors with a rolling shutter that exposes the image line by line. For dynamic scenes/cameras this introduces undesired effects like stretch, shear and wobble. It has been shown earlier that ...
Direct semi-dense SLAM for rolling shutter cameras
2016 IEEE International Conference on Robotics and Automation (ICRA)In this paper, we present a monocular Direct and Semi-dense SLAM (Simultaneous Localization And Mapping) system for rolling shutter cameras. In a rolling shutter camera, the pose is different for each row of each image, and this yields poor pose estimates ...
