1. A dynamic dimensioning system configured to scan one or more objects moving on a transport mechanism, the system comprising:
at least one camera having a field-of-view directed toward the transport mechanism;
a range finder operably coupled with the at least one camera over a communications network;
a tachometer operably coupled with the at least one camera over the communications network, the tachometer configured to configured to output a signal representative of the movement of the transport mechanism; and
a computer operably coupled to the communications network, and configured to perform a dynamic calibration operation comprising:
a calibration estimate routine configured to generate default configuration parameters responsive to selections by a user from among a plurality of pre-defined user inputs via graphical user interface; and
a calibration refinement routine configured to refine the default configuration parameters to generate a completed set of calibration parameters that are set for the at least one camera by performing calculations for:
a refined camera angle for the at least one camera being calibrated;
a refined far working distance for the at least one camera being calibrated; and
a refined camera distance to a scanline for the at least one camera being calibrated.
