Assessment of Photogrammetric Performance Test on Large Areas by Using a Rolling Shutter Camera Equipped in a Multi-Rotor UAV

Applied Sciences
The generation of digital aerial photogrammetry products using unmanned aerial vehicle-digital aerial photogrammetry (UAV-DAP) has become an essential task due to the increasing use of UAVs in the world of geomatics, thanks to their low cost and spatial ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

Journal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...

Secure Mobile-Phone Based Visible Light Communications With Different Noise-Ratio Light-Panel

IEEE Photonics Journal, 2018
We propose and demonstrate a visible light communication (VLC) system using a light-panel and a mobile-phone camera. We also propose the rolling-shutter-effect (RSE) pattern synchronization and demodulation algorithms. By using our developed mobile-phone

UAV‐Based Precision Seed Dropping for Automated Reforestation

Journal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Significant Far‐Right Challenges to Australian Society? The XYZ and AustraliaOne

Australian Journal of Politics &History, EarlyView.
ABSTRACT Scholars who analyse the Australian far‐right from a criminological or security studies perspective propose that activists and groups pose ‘political’ challenges to Australian society. This paper examines the far‐right news website The XYZ and the AustraliaOne political party, and argues that claims that the far‐right may normalise ...

Reimagining the White Child as Other: Taika Waititi's Decolonial Play in James and the Giant Peach With Taika and Friends

Children &Society, EarlyView.
ABSTRACT This article examines how James and the Giant Peach with Taika and Friends (JGPTF) (2020) challenges the colonial logics embedded in Roald Dahl's construction of the universal white child. Through collaborative digital play, humour and Māori relational epistemologies, Taika Waititi unsettles James's position as the normative child of futurity,

Structure and Motion Estimation from Rolling Shutter Video [PDF]

, 2011
The majority of consumer quality cameras sold today have CMOS sensors with rolling shutters. In a rolling shutter camera, images are read out row by row, and thus each row is exposed during a different time interval.

INVESTIGATION OF PHOTOTRIANGULATION ACCURACY WITH USING OF VARIOUS TECHNIQUES LABORATORY AND FIELD CALIBRATION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Nowadays, aerial survey technology using aerial systems based on unmanned aerial vehicles (UAVs) becomes more popular. UAVs physically can not carry professional aerocameras. Consumer digital cameras are used instead.

Trauma and affect in a Holocaust survivor's story: Rosita Fanto's novel Rozalia Alone

Orbis Litterarum, EarlyView.
Abstract My article endeavors to redress the neglect of Rosita Fanto's Rozalia Alone (2010), which deals with a page of history that is less known worldwide, the Holocaust in Romania. Using a trauma studies perspective that mixes with affect theory, the article demonstrates that Rozalia Alone covers in a nutshell the whole magnitude of the late 1930s ...

Reducing Grayscale Value Fluctuation for Mobile-Phone Camera Based VLC System

IEEE Photonics Journal, 2018
Visible light communication (VLC) technology based on mobile-phone camera has attracted more and more attention. Using the rolling-shutter effect of a complementary metal–oxide–semiconductor (CMOS) camera, the VLC system can achieve a ...
