3D Dataset of a twisted bending-active beam element digitized using Structure-from-Motion Photogrammetry

The dataset comprises images (.jpg), a 3D point cloud (.xyz) representing a twisted beam element, as well as refined meshes (.obj) accompanied by material settings files (.mtl) and textures (.png). The data were acquired through Structure-from-Motion (SfM) and Multi-view Stereo (MVS) photogrammetry under controlled lab conditions to digitize a bending-active beam element composed of four twisted plywood strips.

本数据集包含.jpg格式图像、表征扭曲梁单元的.xyz格式三维点云，以及附带材质设置文件（.mtl）与纹理文件（.png）的.obj格式精修网格。该数据集通过在受控实验室环境下，运用运动恢复结构（Structure-from-Motion, SfM）与多视图立体（Multi-view Stereo, MVS）摄影测量技术采集获取，用于对由四根扭曲胶合板条组成的受弯激活梁单元进行数字化建模。
