Rolling Shutter Camera Absolute Pose

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2020
We present minimal, non-iterative solutions to the absolute pose problem for images from rolling shutter cameras. The absolute pose problem is a key problem in computer vision and rolling shutter is present in a vast majority of today's digital cameras. We discuss several camera motion models and propose two feasible rolling shutter camera models for a

Rolling Shutter Super-Resolution

2015 IEEE International Conference on Computer Vision (ICCV), 2015
Classical multi-image super-resolution (SR) algorithms, designed for CCD cameras, assume that the motion among the images is global. But CMOS sensors that have increasingly started to replace their more expensive CCD counterparts in many applications do not respect this assumption if there is a motion of the camera relative to the scene during the ...

Removing rolling shutter wobble

2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010
We present an algorithm to remove wobble artifacts from a video captured with a rolling shutter camera undergoing large accelerations or jitter. We show how estimating the rapid motion of the camera can be posed as a temporal super-resolution problem. The low-frequency measurements are the motions of pixels from one frame to the next.

Simultaneous Video Stabilization and Rolling Shutter Removal

IEEE Transactions on Image Processing, 2021
Due to the delay in the row-wise exposure and the lack of stable support when a photographer holds a CMOS camera, video jitter and rolling shutter distortion are closely coupled degradations in the captured videos. However, previous methods have rarely considered both phenomena and usually treat them separately, with stabilization approaches that are ...

Degeneracies in Rolling Shutter SfM

2016
We address the problem of Structure from Motion (SfM) with rolling shutter cameras. We first show that many common camera configurations, e.g. cameras with parallel readout directions, become critical and allow for a large class of ambiguities in multi-view reconstruction.

Calibration-free rolling shutter removal

2012 IEEE International Conference on Computational Photography (ICCP), 2012
We present a novel algorithm for efficient removal of rolling shutter distortions in uncalibrated streaming videos. Our proposed method is calibration free as it does not need any knowledge of the camera used, nor does it require calibration using specially recorded calibration sequences.

Automated rolling shutter calibration with an LED panel

Optics Letters, 2023
Cameras with rolling shutters (RSs) dominate consumer markets but are subject to distortions when capturing motion. Many methods have been proposed to mitigate RS distortions for applications such as vision-aided odometry and three-dimensional (3D) reconstruction. They usually need known line delay d between successive image rows.

Rolling Shutter Image Compensation

2007
This paper describes corrections to image distortion found on the Sony AIBO ERS-7 robots. When obtaining an image the camera captures each pixel in series, that is there is effectively a 'rolling shutter'. This results in a delay between the capture of the first and last pixel.

Rolling shutter imaging on the electric grid

2018 IEEE International Conference on Computational Photography (ICCP), 2018
Flicker of AC-powered lights is useful for probing the electric grid and unmixing reflected contributions of different sources. Flicker has been sensed in great detail with a specially-designed camera tethered to an AC outlet. We argue that even an untethered smartphone can achieve the same task.

On the observability properties of systems with rolling shutter

2016 54th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2016
We pose the image reconstruction problem for pictures distorted by rolling shutter as an observability problem. In particular, we study the observability properties of linear systems of whom measurements are taken with a pixel-by-pixel evaluation. We do not concentrate on the technical process behind rolling shutter, but introduce and study it as a ...
