1. A method of dimensioning an object for determining shipping volumes, the method comprising;: retrieving a plurality of depth maps of eh object placed on a dimensioning surface from one or more depth-sensing imaging devices; filtering each of the plurality of depth maps retrieved from the one or more depth-sensing imaging devices; 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; generating a point cloud representing the object to be dimensioned using the transformation of the plurality of depth maps; determining edge lengths of the object; determining a height of the object; and calculating a volume of the object.
