3D Photogrammetric-Data for WK19-17(complete)

Research data (*.las, *.ply and *.obj format) which was obtained by Photogrammetric/Computer Vision 3D digitization as well as original images which were the base for the 3D reconstruction process. Explanation about the 3D data format: Las (Is the normal data format for laser scanned point cloud data and also for photogrammetric 3D model.) Ply or Ply + jpg (The software RealityCapture encoded texture mesh in a single ply file while the software Agisoft metashape exported textured mesh in ply format + .jpg.) Obj + mtl + jpg (Obj stores a texture mesh together with mtl and jpg file. Obj file contains information of geometric vertices, texture vertices, vertex normal, polygon face element etc. The Mtl file defines the texture information of the faces. Mtl normally refers to a jpg for storing the actual texture.) Explanation about the mask image (if available): To avoid lots of background information in the 3D reconstruction process, well-aligned images to generate a rough model were applied. Afterwards a mask for each image could be calculated according to the 3D model. In the next step, original images together with the corresponding masks are applied to implement the reconstruction, which is free from the influence of the background information. This dataset is part of the digital gyroscope collection.

研究数据（*.las, *.ply 和 *.obj 格式），该数据由摄影测量/计算机视觉三维数字化获得，以及作为三维重建过程基础的原版图像。关于三维数据格式的说明：Las（是激光扫描点云数据的常规数据格式，也是摄影测量三维模型的常规格式。）Ply 或 Ply + jpg（RealityCapture 软件将纹理网格编码在单个 ply 文件中，而 Agisoft Metashape 软件则将纹理网格以 ply 格式加 .jpg 格式导出。）Obj + mtl + jpg（Obj 文件存储纹理网格以及 mtl 和 jpg 文件。Obj 文件包含几何顶点、纹理顶点、顶点法线、多边形面元素等信息。Mtl 文件定义了面的纹理信息。Mtl 通常指 jpg，用于存储实际纹理。）关于掩码图像（如有）：为避免在三维重建过程中包含大量背景信息，应用了精确对齐的图像以生成粗糙模型。随后，根据三维模型计算每个图像的掩码。在下一步中，应用原始图像及其相应的掩码以实现重建，该重建过程不受背景信息的影响。本数据集是数字陀螺仪收藏品的一部分。有关收藏品及其创建的更多信息，请参阅数据集文档：Niklaus, Maria, 2021, "Gyrolog 数据仓库信息
