A method includes receiving image frames of an inventory. The method includes locating a control point used to determine a spatial search in the image frames and detecting, by a machine learning model, a plurality of storage units in the spatial search. Each storage unit is associated with a unit type from a plurality of unit types. The method includes calculating a storage unit count from a plurality of storage unit counts and for each unit type from the plurality of unit types from the plurality of storage units detected based on depth analysis. Each storage unit count includes a total number of storage units associated with each unit type. The method includes determining a restock status of each unit type based on the storage unit count for each unit type, and automatically generating a replenish request based on the restock status.
