Compressive temporal imaging using a rolling shutter camera array.
Optics Express, 2021 In this work, we present a novel camera array that exploits the electronic rolling shutter to achieve high speed compressive temporal imaging. Traditional compressive temporal imaging makes use of mechanical coded apertures, despite implementation and ...

Rolling Shutter Camera Synchronization with Sub-millisecond Accuracy [PDF]
Proceedings of the 12th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, 2019 A simple method for synchronization of video streams with a precision better than one millisecond is proposed. The method is applicable to any number of rolling shutter cameras and when a few photographic flashes or other abrupt lighting changes are ...

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 ...

Rolling Shutter Camera Relative Pose: Generalized Epipolar Geometry [PDF]
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016 The vast majority of modern consumer-grade cameras employ a rolling shutter mechanism. In dynamic geometric computer vision applications such as visual SLAM, the so-called rolling shutter effect therefore needs to be properly taken into account.

Design of Streaming Data Transmission Using Rolling Shutter Camera-Based Optical Camera Communications [PDF]
Electronics, 2020 This paper addresses a method to transmit streaming data via rolling shutter camera-based optical camera communications (OCC). Since the amount of data that can be contained within one frame is limited, and the continuity of received data cannot be ...

Continuous-Time Spatiotemporal Calibration of a Rolling Shutter Camera-IMU System [PDF]
IEEE Sensors Journal, 2021 The Rolling Shutter (RS) mechanism is widely used in consumer-grade cameras, which are essential parts in smartphones and autonomous vehicles. RS leads to image distortion when the camera moves relative to the scene while capturing images.

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.

Optimal Modulation Technique for Underwater Visible Light Communication Using Rolling-Shutter Sensor
IEEE Access, 2021 The visible light communication (VLC) technique using a rolling-shutter sensor-based commercial camera has an advantage in that the LED and camera mounted on an underwater device (e.g., drone, sensor) can be effectively used as a transmitter (Tx) and a ...
