Direct Sparse Odometry with Rolling Shutter [PDF]
, 2018 Neglecting the effects of rolling-shutter cameras for visual odometry (VO) severely degrades accuracy and robustness. In this paper, we propose a novel direct monocular VO method that incorporates a rolling-shutter model. Our approach extends direct sparse odometry which performs direct bundle adjustment of a set of recent keyframe poses and the depths

Minimal Solvers for Monocular Rolling Shutter Compensation under Ackermann Motion
, 2017 Modern automotive vehicles are often equipped with a budget commercial rolling shutter camera. These devices often produce distorted images due to the inter-row delay of the camera while capturing the image.

R6P - Rolling shutter absolute pose problem [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015 We present a minimal, non-iterative solution to the absolute pose problem for images from rolling shutter cameras. 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 propose several rolling shutter camera models and verify their feasibility for a polynomial solver ...

Spatial Interference Detection for Mobile Visible Light Communication
, 2017 Taking advantage of the rolling shutter effect of CMOS cameras in smartphones is a common practice to increase the transfered data rate with visible light communication (VLC) without employing external equipment such as photodiodes.

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 ...

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 ...
