Wearable devices for courier processing and methods of use thereof

A computer-implemented method for performing courier services using a wearable electronic device, the wearable electronic device comprising a depth camera for detecting object depths in a field of view, the method comprising the following operations performed by one or more processors:

• detecting a dimensioning event based on a signal received from the depth camera, the dimensioning event comprising an input gesture;
• segmenting the field of view from the depth camera into a plurality of regions;
• determining a first region of the plurality of regions, the first region being associated with an object proximate to the input gesture;
• generating a three-dimensional representation of the object based on the first region and the one or more adjacent regions associated with the object;
• determining a location of an invisible vertex of the object not detected by the depth camera by identifying a surface of the object and imposing a rule that the object exhibits a symmetry about an axis associated with the surface;
• determining dimensions of the object in the first region based on and the one or more adjacent regions and the location of the invisible vertex;
• and
• determining a volume of the object based on the determined dimensions of the object.
