Motion and velocity estimation of rolling shutter cameras

Proceedings of the 9th European Conference on Visual Media Production - CVMP '12, 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 ...

Compressive Rolling Shutter Camera Array

Imaging and Applied Optics Congress, 2020
We propose a CMOS-camera array architecture exploiting rolling shutter diversity to generate a compressive forward model that can increase the temporal resolution of the sensed data.

Direct semi-dense SLAM for rolling shutter cameras

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
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 and poor structure estimates when using a state-of-the-art semi-dense direct method designed for ...

Rolling shutter and motion blur removal for depth cameras

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
Structured light range sensors (SLRS) like the Microsoft Kinect have electronic rolling shutters (ERS). The output of such a sensor while in motion is subject to significant motion blur (MB) and rolling shutter (RS) distortion. Most robotic literature still does not explicitly model this distortion, resulting in inaccurate camera motion estimation.

Unified Video Reconstruction for Rolling Shutter and Global Shutter Cameras

IEEE Transactions on Image Processing
Currently, the general domain of video reconstruction (VR) is fragmented into different shutters spanning global shutter and rolling shutter cameras. Despite rapid progress in the state-of-the-art, existing methods overwhelmingly follow shutter-specific paradigms and cannot conceptually generalize to other shutter types, hindering the uniformity of VR ...

Multiple View 3D Reconstruction with Rolling Shutter Cameras

2016
Nowadays Rolling shutter CMOS cameras are embedded on a lot of devices. This type of cameras does not have its retina exposed simultaneously but line by line. The resulting distortions affect structure from motion methods developed for global shutter, like CCD cameras.

Synchronization and rolling shutter compensation for consumer video camera arrays

2009 IEEE Computer Society Conference on Computer Vision and Pattern Recognition Workshops, 2009
Two major obstacles to the use of consumer camcorders in computer vision applications are the lack of synchronization hardware, and the use of a "rolling" shutter, which introduces a temporal shear in the video volume. We present two simple approaches for solving both the rolling shutter shear and the synchronization problem at the same time. The first

High-speed asynchronous Optical Camera Communication using LED and rolling shutter camera

2015 Seventh International Conference on Ubiquitous and Future Networks, 2015
This paper introduces the asynchronous Optical Camera Communication (asynchronous OCC) using LED and rolling shutter camera as a pair of wireless communication. Aiming to enhance the capacity of unidirectional wireless link, the response of camera is measured, and then the operating frequency range, system architecture, decoding procedure and algorithm

Vision-aided inertial navigation with line features and a rolling-shutter camera

2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015
The vast majority of existing methods for vision-aided inertial navigation rely on the detection and tracking of point features in the images. However, in several man-made environments, such as indoor office spaces, straight line features are prevalent, while point features may be sparse.
