  • Mobile low-cost 3D camera maize crop height measurements under field conditions

    Maps of the spatial distribution of crop heights can strongly support agriculture in terms of efficiency and yield optimization. Recently published results of experiments of the 3D Spatial Data Processing research group describe an approach to easily extend regular agricultural machines with low-cost sensors for capturing crop heights while the machine is in the field.…

  • Results of study “Direct derivation of maize plant and crop height from low-cost time-of-flight camera measurements” published

    In agriculture, information about the spatial distribution of crop height is valuable for applications such as biomass and yield estimation, or increasing field work efficiency in terms of fertilizing, applying pesticides, irrigation, etc. Established methods for capturing crop height often comprise restrictions in terms of cost and time efficiency, flexibility, and temporal and spatial resolution…

  • Beyond 3-D: The New Spectrum of LiDAR Applications for Earth and Ecological Sciences

    Capturing and quantifying the world in three dimensions (x,y,z) using light detection and ranging (lidar) technology drives fundamental advances in the Earth and Ecological Sciences (EES). However, additional lidar dimensions offer the possibility to transcend basic 3-D mapping capabilities, including i) the physical time (t) dimension from repeat lidar acquisition and ii) laser return intensity…

  • EGU Session: 3D Point Clouds in Geosciences: Capturing, Analysis and Visualization

    The session “3D Point Clouds in Geosciences: Capturing, Analysis and Visualization” at the EGU 2016 General Assembly achieved high interest and active participation: the lecture room was fully crowded with peopling standing; intensive and lively discussions took place at the posters. Furthermore, the quality of the contributions (oral as well as posters) was high and…

  • Autonomously Operating Low-Cost Static Terrestrial LiDAR

    In order to optimize agricultural processes, near real-time spatial information about in-field variations, such as crop height development (i.e., changes over time), is indispensable. This development can be captured with a LiDAR system. However, its applicability in precision agriculture is often hindered due to high costs and unstandardized processing methods. In our new study we…

  • Press release about our new project 4DEMON

    The Heidelberg University reports in a current press release (in German) about our new project 4DEMON: 4D Near Real-Time Environmental Monitoring, which is funded by the highly competitive Junior Professorship Funding Scheme of the Ministry of Science, Research and Arts, Baden-Wuerttemberg.

  • New research project: 4D Near Real-Time Environmental Monitoring (4DEMON)

    The Ministry of Science, Research and Arts, Baden-Wuerttemberg has funded a new research project called 4DEMON, which will approach the research front of 4D Near Real-Time Environmental Monitoring. Our physical environment underlies permanent changes in space and time with strongly varying triggers, frequencies, magnitudes and also consequences to humans. Monitoring of Earth surface processes (e.g.…
