Hands-On Plant Root System Reconstruction in Virtual Reality

Abstract

VRoot is an immersive extended reality reconstruction tool for root system architectures from 3D volumetric scans of soil columns. We have conducted a laboratory user study to assess the performance of new users with our software in comparison to established software. We utilize a plant model to derive a synthetic root architecture, providing a baseline for reconstruction. This demo showcases the processes and techniques contributing to exact and efficient manual root architecture reconstruction in Virtual Reality. The extraction task typically is the sparse graph-structure extraction from a 3D magnetic-resonance imaging (MRI) data set. We visualize the RSA directly within the MRI and offer selection-set-based methods of adapting and augmenting the root architecture. This application is in productive use at our partner institute, where it is used to analyze complex root images.

Plant phenotyping relevance

根系構造という植物形質をMRIから抽出・再構成するVRツールを開発し、既存ソフトウェアとの性能比較によるユーザー評価も行っているため、植物フェノタイピング手法が中心です。
