Methods for calculating real time package density

Abstract:

Methods and systems for assessing a unit load device (ULD) package density are disclosed herein. An example method includes capturing a primary and secondary image featuring the ULD. The method further includes segmenting the primary image and the secondary image into a plurality of subsections and determining a primary largest depth value and secondary largest depth value for each subsection. The method further includes determining a depth change by comparing the primary largest depth value for each subsection to the secondary largest depth value for each subsection. The method further includes clustering subsections in the secondary image including a respective secondary largest depth value that is substantially similar to a subsection corresponding to a depth change to create a plurality of clusters. The method further includes calculating a wasted volume, and calculating a ULD package density by subtracting the wasted volume from a filled volume of the ULD.
