Volume of a Shipping Container

ship-containerExplosives Risk Managers LLC (ERM) recently obtained some images obtained by a hobbyist using the Pix4D Capture app for smartphones.  We processed the images using Pix4D Mapper photogrammetry software and are impressed with the results.

The image shown is a small portion of the ray cloud reproduction with about 5.5 million 3-D densified points over 2.5 acres.  The 20-foot shipping container has been identified as an object and its volume is shown in the upper right corner.  It computed the volume as 38.6629 cubic meters (cu m) +/-0.610258 cu m.

The actual volume of a 20-ft shipping container is about 38.3 cu m.  So the calculated value differs ever so slightly.  Error could be introduced in defining the base points or by slight variations in the actual size of the container.  Nonetheless, this is impressive and used no ground reference/control points.

ERM is offering engineering services to clients that send us geotagged images for analysis.  Contact us for more details.
