Claim 0:
1. A method for monitoring occupancy in a work area comprising:
accessing a first image recorded by a sensor block at a first time;
detecting a first distribution of objects and a work surface in the first image;
detecting a quantity of humans and a cluster of objects within a distance threshold of the work surface in the first image;
in response to the quantity of humans falling below a human quantity threshold and in response to detecting the cluster of objects within the distance threshold of the work surface, updating an occupancy status of the work surface to indicate the work surface as occupied with humans absent;
accessing a second image recorded by the sensor block at a second time;
detecting a second distribution of objects, absence of humans, absence of clusters of objects, and the work surface present in the work area in the second image;
calculating an object entropy in the work area based on a first difference between the first distribution of objects and the second distribution of objects; and
in response to detecting absence of humans and detecting absence of clusters of objects and in response to the object entropy exceeding an entropy threshold, updating the occupancy status of the work surface to indicate the work surface as vacant.
