The outer box is the final prediction over the whole tracklet (most consistent class that is predicted) and the inner box is the class (species) for the current frame. In this example we have 8 classes of plants. The numbers for each plant are the visual surface area of the plant taken by using a stereo camera and the instance-based semantic segmentation.

IROS 2022 – Towards Autonomous Visual Navigation in Arable Fields

Presented at IROS 2022 Kyoto-Japan Alireza Ahmadi, Michael Halstead, Chris McCool Agricultural Robotics and Engineering University of Bonn Fully autonomous vision-only row-crop field traversal scheme. Proposed a novel multi-crop-row detection and recognition method tested in real fields with cluttered weedy scenes. Autonomously switches between lanes of crops using only RGB cameras fixed to the front and back of the robot. Average navigation deviation from the GPS groundtruth of 3.82cm or approximately 10% of the crop-row distance across the five real crop types.

EasyPBR: A Lightweight Physically-Based Renderer

Presentation for paper by Radu Alexandru Rosu and Sven Behnke: “EasyPBR: A Lightweight Physically-Based Renderer” 16th International Conference on Computer Graphics Theory and Applications (GRAPP), 2021 Modern rendering libraries provide unprecedented realism, producing real-time photorealistic 3D graphics on commodity hardware. Visual fidelity, however, comes at the cost of increased complexity and difficulty of usage, with many rendering parameters requiring a deep understanding of the pipeline. We propose EasyPBR as an alternative rendering library that strikes a balance between ease-of-use and visual quality. EasyPBR consists of a deferred renderer that implements recent state-of-the-art approaches in physically based rendering. It offers an easy-to-use Python and C++ interface that allows high-quality images to be created in only a few lines of code or directly through a graphical user interface. The user can choose between fully controlling the rendering pipeline or letting EasyPBR automatically infer the best parameters based on the current scene composition. The EasyPBR library can help the community to more easily leverage the power of current GPUs to create realistic images. These can then be used as synthetic data for deep learning or for creating animations for academic purposes. http://www.ais.uni-bonn.de/papers/GRAPP_2021_Rosu_EasyPBR.pdf

Virtual Temporal Samples for RNNs: applied to semantic segmentation in agriculture

Normally, to train a recurrent neural network (RNN), labeled samples from a video (temporal) sequence are required which is laborious and has stymied work in this direction. By generating virtual temporal samples, we demonstrate that it is possible to train a lightweight RNN to perform semantic segmentation on two challenging agricultural datasets. full text in arxiv: https://arxiv.org/abs/2106.10118 check My GitHub for interesting ROS-based projects: https://github.com/alirezaahmadi

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.
