INVENTORY MANAGEMENT DEVICE AND INVENTORY MANAGEMENT METHOD

WIPO Patent Application WO/2024/034297

A1

An inventory management device (100) comprises: a registration unit (111) that acquires height data (refer to a height information database (140)) indicating the height of each point included in a region where inventory is placed; a height normalization unit (112) that normalizes the heights of the points by changing any height lower than a threshold value, which is calculated on the basis of a height frequency distribution, to the threshold value; an inventory identification unit (refer to a pile identification unit (114)) that uses machine learning technology (refer to a pile identification model database (170)) based on the normalized height data to extract an inventory region which is a partial region of the region where inventory is present; and a volume calculation unit (115) that partitions the inventory region into a mesh shape, and that calculates the volume of the inventory by finding the sum of the products of the area of each partitioned region and a difference between the height of a point included in the partitioned region and the height of a ground surface.
