Problems solved by technology

However, this method is also difficult to reflect the differences in detail characteristics such as leaf margins and folds among varieties.
The reconstruction has a low sense of reality and cannot reflect the detailed differences between varieties. The reconstruction quality depends on the data quality, so the algorithm is not universal

Abstract

The invention provides a plant leaf three-dimensional modeling method and device, and the method comprises the steps: selecting a leaf template with the highest similarity from a plurality of leaf templates of a corresponding variety in a leaf template library according to the variety and vein information of a target vein, and taking the selected leaf template as the current target vein; transforming the selected leaf template according to the spatial position relationship between the target leaf vein and the leaf vein of the selected leaf template, so that the leaf vein of the selected leaf template is aligned with the target leaf vein; and establishing a control point corresponding relationship between the two veins, and according to the control point corresponding relationship between the two veins, deforming the selected leaf template to obtain a leaf model of the target vein. According to the method, the leaf template library covers a plurality of leaf templates of a plurality of varieties, so that the leaf modeling can be realized only by acquiring the vein information of the to-be-modeled leaf, the model reconstruction quality does not depend on the data quality, the universality is high, and based on the existing leaf template, the difference of detail features such as leaf edges and wrinkles between the varieties can be reflected.

Description

technical field [0001] The invention relates to the field of plant phenotype analysis, in particular to a method and device for three-dimensional modeling of plant leaves. Background technique [0002] Due to factors such as species, cultivation and management measures, plants have significant differences in morphological structure. How to quantitatively characterize this difference in a digital and visual way is a difficult problem in the field of plant phenomics and functional structure modeling. At present, the three-dimensional modeling methods of plant leaves mainly include methods based on mathematical modeling, methods based on three-dimensional digitization, methods based on three-dimensional point cloud reconstruction, and leaf modeling methods driven by veins. [0003] Based on the method of 3D point cloud reconstruction, the 3D point cloud of plant leaves is obtained through 3D scanning or multi-view reconstruction technology, and the 3D reconstruction of leaves ...
