Patent number: 11861543Abstract: Disclosed are various embodiments for optimizing cubic utilization when loading items into a loading space. A current loading configuration of the loading space can be determined according to image data obtained by 3D sensors. Item data (e.g., volume, mass, type, dimensions, etc.) can be determined for incoming items to be loaded into the loading space. The current loading configuration and the item data can be used to determine an item sequence and optimal placement location for the next item to be loaded such that a cubic efficiency of the loading space is maximized and amount of air gaps between items is minimized. The current loading configuration can further be used to determine if a sensing system or an item loading system needs to be repositioned. Whether the next item was placed in the optimal placement can also be verified based on subsequent image data obtained by the 3D sensors.Type: GrantFiled: December 4, 2020Date of Patent: January 2, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Stavan Dholakia, Nicholas Hernandez, Minh Le, Jacob Lauer, Shivani Sheopory
