2013 IEEE International Conference on Computer Vision, 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. It has been shown earlier that rotational shake induced rolling shutter effects in hand-held cell phone capture can be compensated ...

Vibration Detection and Degraded Image Restoration of Space Camera Based on Correlation Imaging of Rolling-Shutter CMOS [PDF]
Sensors, 2023 To mitigate the influence of satellite platform vibrations on space camera imaging quality, a novel approach is proposed to detect vibration parameters based on correlation imaging of rolling-shutter CMOS. In the meantime, a restoration method to address

High Update Rate Attitude Measurement Method of Star Sensors Based on Star Point Correction of Rolling Shutter Exposure [PDF]
Sensors, 2021 Attitude update rate is one of the important indicators of star sensor performance. In order to resolve the problem of the low attitude update rate of star sensors, this paper proposes a star sensor attitude update method based on star point correction ...

Object Distance Estimation Using a Single Image Taken from a Moving Rolling Shutter Camera [PDF]
Sensors, 2020 This paper proposes a technique to estimate the distance between an object and a rolling shutter camera using a single image. The implementation of this technique uses the principle of the rolling shutter effect (RSE), a distortion within the rolling ...

Rolling shutter motion deblurring [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015 Although motion blur and rolling shutter deformations are closely coupled artifacts in images taken with CMOS image sensors, the two phenomena have so far mostly been treated separately, with deblurring algorithms being unable to handle rolling shutter wobble, and rolling shutter algorithms being incapable of dealing with motion blur.

Rolling shutter bundle adjustment [PDF]
2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012 This paper introduces a bundle adjustment (BA) method that obtains accurate structure and motion from rolling shutter (RS) video sequences: RSBA. When a classical BA algorithm processes a rolling shutter video, the resultant camera trajectory is brittle, and complete failures are not uncommon.

Empirical modelling of rolling shutter effect [PDF]
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014 We propose and evaluate a novel methodology to identify the rolling shutter parameters of a real camera. We also present a model for the geometric distortion introduced when a moving camera with a rolling shutter views a scene. Unlike previous work this model allows for arbitrary camera motion, including accelerations, is exact rather than a ...

The WHU Rolling Shutter Visual-Inertial Dataset [PDF]
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).

Calibration and Noise Identification of a Rolling Shutter Camera and a Low-Cost Inertial Measurement Unit [PDF]
Sensors, 2018 A low-cost inertial measurement unit (IMU) and a rolling shutter camera form a conventional device configuration for localization of a mobile platform due to their complementary properties and low costs.
