DEVELOPING A GEODATABASE FOR EFFICIENT UAV-BASED AUTOMATIC CONTAINER CRANE INSPECTION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Inspection of container cranes is an important task to maintain the all-day operation in harbours. In practice, manually carrying out the inspection process is not the best solution due to the complexity, time consumption, and cost. The manual inspection

Markerless point cloud registration with keypoint-based 4-points congruent sets [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
This paper addresses the registration of LiDAR point clouds. More specifically, we present an automatic method for markerless registration of two such point clouds given in arbitrary local scan coordinates – i.e.

MIMO-SAR Interferometric Measurements for Wind Turbine Tower Deformation Monitoring

Energies, 2023
Deformations affect the structural integrity of wind turbine towers. The health of such structures is thus assessed by monitoring. The majority of sensors used for this purpose are costly and require in situ installations.

Positional accuracy in close-range photogrammetry through Topography and Geodesy

Revista de Arquitectura (Bogotá), 2023
Computational three-dimensional modelling can be used to reconstruct real-world objects with all their details and conservation conditions. Photogrammetry offers products with accuracy, in addition to the flexibility of execution of simple and complex projects, according to the simplicity and speed in data acquisition.

An Approach for RGB-Guided Dense 3D Displacement Estimation in TLS-Based Geomonitoring [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Estimating 3D deformation with high spatial resolution from TLS point clouds is beneficial for geomonitoring. Existing methods for this task primarily rely on geometric data. They do not use radiometric information although it is often available as well.

ADVANCES IN HYPERSPECTRAL AND MULTISPECTRAL IMAGE FUSION AND SPECTRAL UNMIXING [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In this work, we jointly process high spectral and high geometric resolution images and exploit their synergies to (a) generate a fused image of high spectral and geometric resolution; and (b) improve (linear) spectral unmixing of hyperspectral ...
