A Skeletal Camera Network for Close-range Images with a Data Driven Approach in Analyzing Stereo Configuration [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2022
Structure-from-Motion (SfM) techniques have been widely used for 3D geometry reconstruction from multi-view images. Nevertheless, the efficiency and quality of the reconstructed geometry depends on multiple factors, i.e., the base-height ratio ...

Supervising the New with the Old: Learning SFM from SFM [PDF]

open access: yes, 2018
Recent work has demonstrated that it is possible to learn deep neural networks for monocular depth and ego-motion estimation from unlabelled video sequences, an interesting theoretical development with numerous advantages in applications. In this paper, we propose a number of improvements to these approaches.

SfM photogrammetry for GeoArchaeology [PDF]

open access: yes, 2020
Geoarchaeological studies have benefits from new technological developments in remote-sensing technologies that have become an integral and important part of the archeological researches. In particular, structure-from-motion (SfM) photogrammetry is one of the most successful emerging techniques in high-resolution topography (HRT) and provides ...

Aboveground biomass estimation in linear forest objects: 2D- vs. 3D-data

open access: yesJournal of Forest Science, 2018
Wood-chips of linear forest objects (hedge banks and roadside plantings) are used as sustainable energy supply in wood-chip heating systems. However, wood yield of linear forest objects is very heterogeneous and hard to estimate in advance.

Correcting Image Refraction: Towards Accurate Aerial Image-Based Bathymetry Mapping in Shallow Waters

open access: yesRemote Sensing, 2020
Although aerial image-based bathymetric mapping can provide, unlike acoustic or LiDAR (Light Detection and Ranging) sensors, both water depth and visual information, water refraction poses significant challenges for accurate depth estimation. In order to

Historical Aerial Surveys Map Long-Term Changes of Forest Cover and Structure in the Central Congo Basin

open access: yesRemote Sensing, 2020
Given the impact of tropical forest disturbances on atmospheric carbon emissions, biodiversity, and ecosystem productivity, accurate long-term reporting of Land-Use and Land-Cover (LULC) change in the pre-satellite era (<1972) is an imperative.
