1. A method for maintaining perpetual inventory within a store comprises:
accessing a first radar scan of a first inventory structure within a store;
locating a first slot volume defining a first slot in the first radar scan;
retrieving a first volumetric definition of a first product type expected in the first slot;
extracting a first volumetric representation of a first set of product units intersecting the first slot volume in the first radar scan;
segmenting the first volumetric representation by the first volumetric definition to calculate a first quantity of the first set of product units occupying the first slot; and
updating a stock record of the store to reflect the first quantity of the first set of product units occupying the first slot.
