Automating Ground Control Point Detection in Drone Imagery: From Computer Vision to Deep Learning

open access: yesRemote Sensing
Drone-based photogrammetry typically requires the task of georeferencing aerial images by detecting the center of Ground Control Points (GCPs) placed in the field. Since this is a very labor-intensive task, it could benefit greatly from automation.

Chiral perovskites for next‐generation chiral optoelectronics and spintronics

open access: yesFlexMat, EarlyView.
Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...

Accuracy assessment of RTK/PPK UAV-photogrammetry projects using differential corrections from multiple GNSS fixed base stations

open access: yesGeocarto International, 2023
Unmanned aerial vehicles (UAVs) equipped with global navigation satellite system-real-time kinematic (GNSS RTK) receivers allow direct georeferencing of the photogrammetric project without using ground control points (GCPs).

Accuracy Assessment of a UAV Direct Georeferencing Method and Impact of the Configuration of Ground Control Points

open access: yesDrones, 2022
Unmanned aerial vehicles (UAVs) can obtain high-resolution topography data flexibly and efficiently at low cost. However, the georeferencing process involves the use of ground control points (GCPs), which limits time and cost effectiveness.

Effective Altruism and Care Ethics

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Effective altruism (EA) has received some of its most vocal criticisms from supporters of care ethics. In this article I take a comparative approach to determine whether a compelling critique of EA can emerge from care ethics at the ethical level, and more generally how much common ground can be found between the two.
