目的阐明根的构型对于理解树根的功能具有重要意义。3D激光扫描重建根系的3D结构，精度高，但设备庞大且昂贵。多视点立体摄影测量（SfM-MVS）方法从多幅图像重建物体的3D结构。这种方法是适合于现场研究，因为它获得的3D数据与市售的数码相机。我们在这项研究中的目的是测试的适用性的SfM-MVS方法的形态测量树rootsystem.MethodsThe三维根系模型创建使用虚拟和三个黑松（黑松）根系统。使用相机从根系收集图像数据，并使用免费软件VisualSfM和MeshLab重建。我们评估的准确性形态数据估计的3D模型，通过比较它们与真实的数据从手动测量的根system.ResultsThe三维重建的虚拟和黑松根系统是成功的。松树根系形态特征的均方根误差值在4 - 24%之间，这对于成功的3D模型来说足够准确。结论SfM-MVS方法是一种基于非专用设备和免费软件的树木根系三维结构的新工具。从重建的模型可以成功地测量它的形态特征。
PurposeClarification of root architecture is important for understanding tree root functions. 3D laser scanning reconstructs the 3D structure of root system with high accuracy, but the devices are large and expensive. The Structure-from-Motion with multi-view stereo-photogrammetry (SfM-MVS) method reconstructs the 3D structure of an object from multiple images. This method is suitable for field research because it acquires the 3D data with a commercially available digital camera. Our aim in this study was to test the applicability of the SfM-MVS method for morphological measurement of tree root systems.MethodsThe 3D root system model was created using a dummy and three black pine (Pinus thunbergii) root systems. Image data were collected from the root systems using a camera and reconstructed using the free software, VisualSfM and MeshLab. We evaluated the accuracy of morphological data estimated from the 3D models by comparing them with real data obtained from manual measurements of the root systems.ResultsThe 3D reconstructions of the dummy and black pine root systems were successful. The root mean squared error values for the morphological features in the pine root systems ranged from 4 to 24%, which was sufficiently accurate for a successful 3D model. However, the RMSE values were larger than that of dummy root, ranging from 2 to 9%.ConclusionThe SfM-MVS method is a new tool, based on non-specialised equipment and free software, to obtain the 3D structure of tree root systems. The morphological features of it can be successfully measured from the reconstructed models.
