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.

A NOVEL TECHNIQUE FOR PRECISION GEOMETRIC CORRECTION OF JITTER DISTORTION FOR THE EUROPA IMAGING SYSTEM AND OTHER ROLLING-SHUTTER CAMERAS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 We use simulated images to demonstrate a novel technique for mitigating geometric distortions caused by platform motion (“jitter”) as two-dimensional image sensors are exposed and read out line by line (“rolling shutter”).

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 ...

Rolling Shutter Homography and its Applications
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021 In this article we study the adaptation of the concept of homography to Rolling Shutter (RS) images. This extension has never been clearly adressed despite the many roles played by the homography matrix in multi-view geometry. We first show that a direct point-to-point relationship on a RS pair can be expressed as a set of 3 to 8 atomic 3x3 matrices ...

Analysis and Compensation of Rolling Shutter Effect [PDF]
IEEE Transactions on Image Processing, 2008 Due to the sequential-readout structure of complementary metal-oxide semiconductor image sensor array, each scanline of the acquired image is exposed at a different time, resulting in the so-called electronic rolling shutter that induces geometric image distortion when the object or the video camera moves during image capture. In this paper, we propose

The Fast and the Distorted – How Sensor Readout Shapes Image-based 3D Modelling [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesA photographic shutter regulates the duration of light reaching a photosensitive surface. Modern digital cameras employ diverse mechanical, electronic, or hybrid shutter technologies to synchronise light admission with a sensor's capacity to collect and ...

LINE OF SIGHT AUTO-CALIBRATION FOR CO3D ROLLING SHUTTER MATRIX DETECTOR [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 The accurate calibration of the line of sight (LOS) is very important for a high-resolution imaging satellite, especially in a system as Co3D, whose mission is to produce 3D elevation models.
