Du, Shenglan (author), Lindenbergh, R.C. (author), Ledoux, H. (author), Stoter, J.E. (author), Nan, L. (author)Laser scanning is an effective tool for acquiring geometric attributes of trees and vegetation, which lays a solid foundation for 3-dimensional tree modelling. Existing studies on tree modelling from laser scanning data are vast. However, some works cannot guarantee sufficient modelling accuracy, while some other works are mainly rule-based and...journal article 2019

Zhou, K. (author), Lindenbergh, R.C. (author), Gorte, Ben (author)Up-to-date 3D city models are needed for many applications. Very-high-resolution (VHR) images with rich geometric and spectral information and a high update rate are increasingly applied for the purpose of updating 3D models. Shadow detection is the primary step for image interpretation, as shadow causes radiometric distortions. In addition,...journal article 2019

Shen, Y. (author), Lindenbergh, R.C. (author), Wang, Jinguo (author), Ferreira, Vagner G. (author)Bricks are the vital component of most masonry structures. Their maintenance is critical to the protection of masonry buildings. Terrestrial Light Detection and Ranging (TLidar) systems provide massive point cloud data in an accurate and fast way. TLidar enables us to sample and store the state of a brick surface in a practical way. This...journal article 2018

Influence of domain shift factors on deep segmentation of the drivable path of an autonomous vehicleBormans, R. P.A. (author), Lindenbergh, R.C. (author), Karimi Nejadasl, F. (author)One of the biggest challenges for an autonomous vehicle (and hence the WEpod) is to see the world as humans would see it. This understanding is the base for a successful and reliable future of autonomous vehicles. Real-world data and semantic segmentation generally are used to achieve full understanding of its surroundings. However, deploying...journal article 2018

Van Natijne, A. L. (author), Lindenbergh, R.C. (author), Hanssen, R.F. (author)Build on soft soil, close to sea level the Netherlands is at high risk for the effects of subsidence and deformation. Interferometric Synthetic Aperture Radar (InSAR) is successfully used to monitor the deformation trends at millimetre level. Unfortunately the InSAR deformation trends suffer from poor geolocation estimates, limiting the...journal article 2018

Zhou, K. (author), Gorte, B. (author), Lindenbergh, R.C. (author), Widyaningrum, E. (author)Change detection is an essential step to locate the area where an old model should be updated. With high density and accuracy, LiDAR data is often used to create a 3D city model. However, updating LiDAR data at state or nation level often takes years. Very high resolution (VHR) images with high updating rate is therefore an option for change...journal article 2018

Widyaningrum, E. (author), Lindenbergh, R.C. (author), Gorte, B.G.H. (author), Zhou, K. (author)Various kinds of urban applications require true orthophotos. True orthophoto generation requires a DSM (Digital Surface Model) to project the photo orthogonally and minimize geometric distortion due to topographic variance. DSMs are often generated from airborne laser scan data. In urban scenes, DSM data may fail to deliver sharp and...journal article 2018

Wang, J. (author), Lindenbergh, R.C. (author)Urban trees are an important component of our environment and ecosystem. Trees are able to combat climate change, clean the air and cool the streets and city. Tree inventory and monitoring are of great interest for biomass estimation and change monitoring. Conventionally, parameters of trees are manually measured and documented in situ, which...journal article 2018

Puente, I. (author), Lindenbergh, R.C. (author), Van Natijne, A. (author), Esposito, R. (author), Schipper, H.R. (author)Vulnerability of buildings to natural and man-induced hazards has become a main concern for our society. Ensuring their serviceability, safety and sustainability is of vital importance and the main reason for setting up monitoring systems to detect damages at an early stage. In this work, a method is presented for detecting changes from laser...journal article 2018
