To make good decisions, it is vital to know the current condition of the field. Core Project 1 develops novel ground and aerial vehicles that operate autonomously and provide precisely georeferenced, phenotypic data from single plant organs over the experimental plot to the field scale. We register 3D structural models of the same plant over time, leading to a 4D reconstruction. Our aim is to develop a new generation of mapping systems as well as a better understanding of the spatio-temporal dynamics of structural and functional plant traits. The goal is to reconstruct several hundred individual plants per day in an experimental field design.

RSS 2020′: LatticeNet: Fast Point Cloud Segmentation Using Permutohedral Lattices
LatticeNet: Fast Point Cloud Segmentation Using Permutohedral Lattices by Radu Alexandru Rosu, Peer Schütt, Jan Quenzel, Sven Behnke Deep convolutional neural networks (CNNs) have shown outstanding performance in the task of semantically segmenting images. However, applying the same methods on 3D data still poses challenges due to the heavy memory requirements and the lack of structured data. Here, we propose LatticeNet, a novel approach for 3D semantic segmentation, which takes as input raw point clouds. A PointNet describes the local geometry which we embed into a sparse permutohedral lattice. The lattice allows for fast convolutions while keeping a low memory footprint. Further, we introduce DeformSlice, a novel learned data-dependent interpolation for projecting lattice features back onto the point cloud. We present results of 3D segmentation on various datasets where our method achieves state-of-the-art performance.
