Methods, apparatus, and systems are described for dynamically transforming scan data representing a container's loaded volume using a scanning sensor node mounted above storage space within the container. The scanning sensor node generally includes a memory, a depth sensor oriented above and towards the storage space, an identification scanner, and a communications interface to an external managing node. The identification scanner identifies an item being loaded into the storage space and the depth sensor responsively scans the storage space to generate the scan data. The scanning sensor node determines if the item is at least partially not visible to the depth sensor based upon the generated scan data and dynamically transforms the scan data into refined scan data based on this determination and upon material dimension data associated with the item.
