Rollvox: Real-Time and High-Quality LiDAR Colorization with Rolling Shutter Camera
IEEE/RJS International Conference on Intelligent RObots and Systems, 2023In this study, we propose a novel system for real-time coloring LiDAR point clouds with a low-cost RS camera. The main challenges are dealing with the motion distortion of the RS camera and the multi-sensor time synchronization.

Spatial-Temporal Measurement Alignment of Rolling Shutter Camera and LiDAR
IEEE Sensors Letters, 2022This letter proposes a novel method to fuse the asynchronized outputs from a rolling shutter camera and a spinning LiDAR mounted on a moving vehicle. Compared with traditional methods only relying on intrinsic/extrinsic calibration, the proposed method ...

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.

Multistate Constrained Invariant Kalman Filter For Rolling Shutter Camera And Imu Calibration
International Conference on Information Photonics, 2020In this paper, we propose a novel algorithm for joint calibration of a rolling shutter camera and inertial sensors. Specifically, the proposed method performs online calibration to estimate the camera intrinsics, the readout time, the extrinsics and the ...

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 ...
