This study provides an accurate and efficient method to reconstruct detailed and high-resolution digital 3D models of carpological materials by photogrammetric method, in which only about 100 to 150 images are required for each model reconstruction. The 3D models reflect the realistic morphology and genuine color of the carpological materials. The 3D models are scaled to represent the true size of the materials even as small as 3 mm in diameter. The interfaces are interactive, in which the 3D models can be rotated in 360° to observe the structures and be zoomed to inspect the macroscopic details. This new platform is beneficial for developing a virtual herbarium of carpological collection which is thus the most important to botanical authentication and education.
本研究提供了一种通过摄影测量方法准确、高效地重建详细、高分辨率的孢粉材料数字 3D 模型的方法，其中每个模型重建仅需约 100 到 150 张图像。3D 模型反映了孢粉材料的真实形态和真实颜色。3D 模型按比例缩放，以代表材料的真实尺寸，即使直径小至 3 毫米也能如此。界面是交互式的，其中 3D 模型可以 360°旋转以观察结构，并放大以检查宏观细节。这个新平台有利于开发孢粉收藏的虚拟标本馆，这对植物学鉴定和教育来说是最重要的。
