Datasets of captured images of three different devices for photogrammetry calculation comparison and integration into a laserscan point cloud of a built environment

The presented data article aims to provide the whole dataset obtained during an experiment of updating laser scan point clouds with photogrammetry meshes. In this context, the data quality and calculation time of photogrammetry models from different recording devices and different software solutions were compared. It was investigated whether photos from smartphones are also appropriate for updating point clouds by using photogrammetry in a factory environment. The photos of a technical installation were taken in 08:30 min with these three devices: Nikon D810 with Sigma art 24mm, iPhone 6 and iPhone XS. With each of the mentioned devices, three datasets have been created to provide enough data for the comparisons. One dataset (photos in .TIFF) of the iPhone XS is provided. The results of the data sets are used for a photogrammetry mesh quality comparison and a calculation time comparison. For the mesh quality comparison, visual qualitative inspections were performed on the models and the results were compared. Furthermore, all settings in the RealityCapture BETA 1.0.3.9696 ppi and Meshroom 2019 2.0 software are provided. A comparison of the quality of the photogrammetric 3D meshes was performed by comparing the rendering results. The dataset of the iPhone XS can be used to compare further photogrammetry software or single algorithms. Besides the images, the initial point cloud of the laser scanner is provided. Also included is the combined file which consists of the laser scan point cloud and the photogrammetry mesh of the end of the experiment.

本篇数据集论文旨在提供实验过程中通过摄影测量网格更新激光扫描点云所获取的完整数据集。在此背景下，对来自不同记录设备和不同软件解决方案的摄影测量模型的数据质量和计算时间进行了比较。研究是否可以通过在工厂环境中运用摄影测量技术，使用智能手机拍摄的照片来更新点云。使用这三款设备：尼康D810搭配SIGMA art 24mm镜头、iPhone 6和iPhone XS，于08:30分钟内拍摄了技术装置的照片。针对上述每种设备，均创建了三个数据集，以提供足够的数据进行比较。提供了iPhone XS的一个数据集（.TIFF格式的照片）。数据集的结果被用于进行摄影测量网格质量比较和计算时间比较。在网格质量比较中，对模型进行了视觉定性检查，并将结果进行了对比。此外，还提供了RealityCapture BETA 1.0.3.9696 ppi和Meshroom 2019 2.0软件中的所有设置。通过比较渲染结果，对摄影测量3D网格的质量进行了比较。iPhone XS的数据集可用于进一步比较摄影测量软件或单个算法。除了图像外，还提供了激光扫描仪的初始点云。此外，还包括了由实验结束时激光扫描点云和摄影测量网格组合而成的文件。
