1. A method comprising:
accessing a first definition associating a vacant condition and a first set of significant object types for a work area;
accessing a second definition associating an occupied condition and a second set of significant object types for the work area;
at a first time:
accessing a first image recorded by a sensor block and depicting a workstation in the work area;
detecting a first set of objects in the first image; and
in response to detecting a first intersection of the first set of objects with the first set of significant object types, interpreting a first occupancy condition of the workstation according to the first definition; and
at a second time:
accessing a second image recorded by the sensor block;
detecting a second set of objects in the second image; and
in response to detecting a second intersection of the second set of objects with the second set of significant object types, interpreting a second occupancy condition of the workstation according to the second definition; and
calculating a first workstation occupancy rate for the work area based on the first occupancy condition and the second occupancy condition.
