Rolling Shutter Camera Absolute Pose
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020We 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 Camera Calibration [PDF]
2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013 Rolling Shutter (RS) cameras are used across a wide range of consumer electronic devices-from smart-phones to high-end cameras. It is well known, that if a RS camera is used with a moving camera or scene, significant image distortions are introduced.

Performance of rolling shutter and global shutter camera in optical camera communications
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015Optical Camera Communication (OCC) is considered as an extension of IEEE 802.15.7 specification by same communication channel. Different with another technique, Optical Camera Communication used image sensor for receiver, so the characteristic of image sensor will effect on the operation and performance.

A Simplified Model for the Rolling Shutter Based Camera in Optical Camera Communications [PDF]
2019 15th International Conference on Telecommunications (ConTEL), 2019 A simplified model of the camera for optical camera communications (OCC) based on the rolling shutter effect is proposed and experimentally verified. In OCC, the key parameters are the exposure time, which is proportional to the DC gain and inversely proportional to the bandwidth, and the rolling shutter delay or the sampling period.

Compressive Rolling Shutter Camera Array
Imaging and Applied Optics Congress, 2020We 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.

Motion and velocity estimation of rolling shutter cameras
Proceedings of the 9th European Conference on Visual Media Production - CVMP '12, 2012Most 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 ...

Unified Video Reconstruction for Rolling Shutter and Global Shutter Cameras
IEEE Transactions on Image ProcessingCurrently, 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 ...

Direct semi-dense SLAM for rolling shutter cameras
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016In 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 ...

Vision-aided inertial navigation with rolling-shutter cameras
The International Journal of Robotics Research, 2014In this paper, we focus on the problem of pose estimation using measurements from an inertial measurement unit and a rolling-shutter (RS) camera. The challenges posed by RS image capture are typically addressed by using approximate, low-dimensional representations of the camera motion. However, when the motion contains significant accelerations (common
