Relative Pose Estimation For Stereo Rolling Shutter Cameras [PDF]
2020 IEEE International Conference on Image Processing (ICIP), 2020 In this paper, we present a novel linear algorithm to estimate the 6 DoF relative pose from consecutive frames of stereo rolling shutter (RS) cameras. Our method is derived based on the assumption that stereo cameras undergo motion with constant velocity around the center of the baseline, which needs 9 pairs of correspondences on both left and right ...

400 m rolling-shutter-based optical camera communications link [PDF]
Optics Letters, 2020 In this Letter, we develop a novel technique, to the best of our knowledge, to increase the link span ( L s ) of a rolling shutter (RS)-based optical camera communications (OCC) system by reducing the spatial bandwidth of the camera in the out-of-focus regions.

100,000 frames-per-second compressive imaging with a conventional rolling-shutter camera by random point-spread-function engineering. [PDF]
Optics Express, 2020 We demonstrate an approach that allows taking videos at very high frame-rates of over 100,000 frames per second by exploiting the fast sampling rate of the standard rolling-shutter readout mechanism, common to most conventional sensors, and a compressive-

The WHU Rolling Shutter Visual-Inertial Dataset
IEEE Access, 2020 The vast majority of modern consumer cameras employ a rolling shutter (RS) mechanism which has a price and electronic advantage to global shutter (GS).

Exploiting the Rolling Shutter Read-Out Time for ENF-Based Camera Identification
Applied Sciences, 2023 The electric network frequency (ENF) is a signal that varies over time and represents the frequency of the energy supplied by a mains power system. It continually varies around a nominal value of 50/60 Hz as a result of fluctuations over time in the ...

Spatiotemporal Optimization for Rolling Shutter Camera Pose Interpolation [PDF]
VISIGRAPP, 2017 Rolling Shutter cameras are predominant in the tablet and smart-phone market due to their low cost and small size. However, these cameras require specific geometric models when either the camera or the scene is in motion to account for the sequential exposure of the different lines of the image.

Robust OCC System Optimized for Low-Frame-Rate Receivers
Sensors, 2022 Light emitting diodes (LED) are becoming the dominant lighting elements due to their efficiency. Optical camera communications (OCC), the branch of visible light communications (VLC) that uses video cameras as receivers, is a suitable candidate in ...

MULTISPECTRAL IMAGE CAPTURING WITH FOVEON SENSORS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 This article describes a specific image quality problem using an UAV and the commercially available multispectral camera Tetracam ADC Lite. The tests were carried out with commercially available UAV Multirotor MR-X 8 performed under normal use and ...

, 2013 A 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.
