Motion and velocity estimation of rolling shutter cameras
Oliver Grau, Julien Pansiot · 2012
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.
