Sensor systems and methods for monitoring unloading of cargo

A computer-implemented method comprising:

• receiving first measured data generated by a first plurality of sensors arranged about an opening associated with a door through which packages are unloaded from a vehicle or trailer, the first plurality of sensors being configured to measure an unpacked depth of the vehicle or trailer;
• determining an empty volume over time of the vehicle or trailer based on the first measured data as packages are being unpacked from the vehicle or trailer;
• determining a rate of unloading or unpacking based on measured data generated by a second plurality of sensors on a conveyor belt;
• and
• generating instructions regarding loading packages in a subsequent vehicle or trailer based on the determined empty volume over time of the vehicle or trailer.

A sensor system comprising:

• a sensor arranged about an opening associated with a door through which packages are unloaded from a vehicle or trailer, the sensor being configured to oscillate along the width or length of the opening to measure an unpacked depth of the vehicle or trailer;
• a processor in communication with the sensor, wherein the processor is configured to:
• receive first measured data generated by the sensor;
• determine an empty volume over time of the vehicle or trailer based on the first measured data as packages are being unpacked from the vehicle or trailer;
• and
• generate instructions regarding loading packages in a subsequent vehicle or trailer based on the determined empty volume over time of the vehicle or trailer.
