Much like with the Creating arbitrary 3D objects for PostGIS recipe, we will be taking an image series and converting it into a point cloud. In this case, however, our image series will be from UAV imagery. Download the image series included in the code folder for this chapter, uas_flight, and feed it into VisualSFM (check http://ccwu.me/vsfm/for more information on how to use this tool); in order to retrieve a point cloud, name it uas_points.ply (this file is also included in this folder in case you would rather use it).
The input for PostGIS is the same as before. Create a JSON file and use PDAL store it into the database:
{ "pipeline": [{ "type": "readers.ply", "filename": "/data/uas_flight/uas_points.ply" }, { "type": "writers.pgpointcloud", ...
