Supporting data for "A digital twin framework of low-altitude construction activities based on fixed-view 4D point clouds"

This dataset contains a Unity project and sample point cloud files. This dataset mainly supports the use of Unity synthetic datasets for related transfer learning work. The Unity project is a modular integrated construction virtual construction project. The point cloud sample file is 1512 frames of synthetic point cloud collected during the construction process and the spatial position annotation of the mic module corresponding to each frame. The point cloud data includes two formats: pcd and npy, and the annotation data is in txt format.
