Old barn (georeferenced scan)

3D Model

This barn was scanned using a similar DIY direct georeferencing 3D-scanner as shown in this youtube-video: https://www.youtube.com/watch?v=WE_fD6qsLKQ. If you are interested in this tech, please take a look at the video and it’s description. Model shown in the video here: https://skfb.ly/6XUtD. In this scan also raster camera tracking was used, giving initial estimates for camera locations/orientations when taking pictures to be used as textures.

Faking:

• Roof was generated in point cloud-level because I couldn’t reach up enough with the hand held scanner.
• Few outliers/errors were removed from the mesh and point clouds.
• Minor editing of the rasters.

Data used to generate this model (relevant GNSS and lidar-data, point clouds, rasters and MeshLab project): https://github.com/GNSS-Stylist/3D_Scan_Barn (about 3.6 GB).

When the location of the RTK-base used when scanning is known, this (including points in the scan) could be placed to it’s original location/orientation with estimated accuracy of few cm.
