1. A method of dimensioning an object for determining shipping volumes, the method comprising: retrieving a plurality of depth maps of an object placed on a dimensioning surface from one or more depth-sensing imaging devices using a host processor; filtering each of the plurality of depth maps retrieved from the one or more depth-sensing imaging devices using the host processor; applying a bounding volume to each of the plurality of depth maps retrieved using the host processor, the bounding volume defining a three dimensional hexahedron aligned to the world co-ordinate system and representing an allowable space for points of a depth map to be considered for dimensioning; transforming each depth map into a world co-ordinate system in three dimensional space utilizing calibration parameters of each of the one or more depth-sensing imaging devices using the host processor; generating a point cloud via the host processor representing the object to be dimensioned using the transformation of the plurality of depth maps; determining edge lengths of the object using the host processor; determining a height of the object using the host processor; and calculating a volume of the object using the host processor.
