  • New paper published: ‘Effects of Reduced Terrestrial LiDAR Point Density on High-Resolution Grain Crop Surface Models in Precision Agriculture.’

    We are happy to announce that a new paper with the title Effects of Reduced Terrestrial LiDAR Point Density on High-Resolution Grain Crop Surface Models in Precision Agriculture has been published in the special issue Agriculture and Forestry: Sensors, Technologies and Procedures in the journal Sensors: 3D geodata play an increasingly important role in precision…

  • MUSIEKE – Multidimensional Perceptibility of Cultural Heritage

    The newly funded multidisciplinary research project MUSIEKE investigates the perceptibility and visibility of cultural heritage in multiple dimensions in urban, landscape, museum and virtual spaces. Three-dimensional (3D) data acquisition, processing, modeling and web-based visualization & analysis will provide fundamental input to the derivation and explanation of complex causal relationships of cultural heritage in time and…

  • Field experiment: deriving pedestrian sidewalk information using LIDAR technology

    On 11th of September, the second experiment for the CAP4Access project for Heidelberg pilot city was performed by Smart Simulation group (led by Mohamed Bakillah) with collaboration of LIDAR research group of Heidelberg University. Bernhard Höfle, Amin Mobasheri and Evelyn Schmitz participated in this fieldwork, using RIEGL VZ-400 laser scanning device in order to collect…

  • Online article in 3D Visualization World Magazine: UNESCO World Heritage Site Lorsch Abbey

    The online magazine 3D Visualization World (www.3dvisworld.com) features an article about the 3D capturing campaigns at Lorsch Abbey: ‘The UNESCO World Heritage Site of Lorsch Abbey is located in Hesse roughly between Heidelberg and Frankfurt/Main, Germany. Laser scanners generating 3D point clouds of the structure and photogrammetric Structure-from-Motion (SfM) approaches were used to study and…
