Airborne light detection and ranging (LiDAR) point density analysis

Balsa Barreiro, José; Avariento Vicent, Joan Pere; Lerma García, José Luis (Academic Journals, 2012-08)

The point density is a preeminent parameter on airborne laser scanner surveys. It is not only related to accuracy but costs and savings. The lack of uniformity of the point density across the survey is well-known in ...
Drill Bit Grading Using LiDAR and Imagery on the Apple Smart Devices

Jia, Fengman; Lichti, Derek; Shor, Roman; Khawaja, Arsh; Kang, Min; Kepler, Max (Editorial Universitat Politècnica de València, 2023-01-27)

[EN] Reservoir development in the petroleum industry starts with the drill bit. A drill bit’s dull condition must be closely monitored since it significantly influences the efficiency and the cost of drilling operations. ...
Forecasting Post-Earthquake Rockfall Activity

Olsen, Michael; Massey, Chris; Leshchinsky, Ben; Wartman, Joseph; Senogles, Andrew (Editorial Universitat Politècnica de València, 2023-01-27)

[EN] Important infrastructure such as highways or railways traverse unstable terrain in many mountainous and scenic parts of the world. Rockfalls and landslides result in frequent maintenance needs, system unreliability ...
Keypoint-based deformation monitoring using a terrestrial laser scanner from a single station: Case study of a bridge pier

Medic, Tomislav; Ruttner, Pia; Holst, Christoph; Wieser, Andreas (Editorial Universitat Politècnica de València, 2023-01-27)

[EN] Terrestrial laser scanners (TLSs) offer a possibility for more automated and efficient deformation monitoring of civil engineering structures with higher spatial resolution than standard methods, as well as without ...
Monitorización de cambios en la lámina libre de agua en humedales mediante teledetección

Pena Regueiro, Jesús (Universitat Politècnica de València, 2023-09-07)

[ES] Los humedales son uno de los ecosistemas que reciben mayor atención por parte de la comunidad científica. Su importancia se puede explicar teniendo en cuenta que ayudan a mitigar los efectos de inundaciones, pueden ...
The potential of UAV-based Laser Scanning for Deformation Monitoring. Case Study on a Water Dam

Dreier, Ansgar; Kuhlmann, Heiner; Klingbeil, Lasse (Editorial Universitat Politècnica de València, 2023-01-27)

[EN] The use of unmanned aerial vehicles (UAV) in monitoring applications is constantly increasing due to the improvement in sensor technology and the associated higher accuracy that can be achieved. As a result, UAV-based ...
UAV oblique photogrammetry and lidar data acquisition for 3D documentation of the Hercules Fountain

Chiabrando, Filiberto; Spanò, Antonia; Sammartano, Giulia; Teppati Losè, Lorenzo (Universitat Politècnica de València, 2017-05-22)

[EN] This paper discusses some enhancements concerning 3D modelling, and the integration and comparison of 3D data from aerial and terrestrial sensors, developed by innovative geomatics techniques around the metric ...
Vibration monitoring of a bridge using 2D profile laser scanning: Lessons learned from the comparison of two spatio-temporal processing strategies

Meyer, Nicholas; Schmid, Lorenz; Wieser, Andreas; Medic, Tomislav (Editorial Universitat Politècnica de València, 2023-01-27)

[EN] Profile laser scanning allows sub-millimeter precise contact-free measurements with high spatial and temporal resolution. That makes it an appealing solution for structural health monitoring focusing on vibrations of ...
