Abstract: A system and related methods for volume dimensioning may be implemented by a smartphone, pad, tablet, or similar mobile computing device configured with a three-dimensional imaging system. The system may recognize the edges and corners of an object and infer its dimensions, from which a volume and dimensional weight can be calculated. The system may utilize the determined dimensions to allocate shipping resources to most efficiently and safely transport a shipment through a supply chain, assess damage to an object, assess the compliance of carry-on baggage to size requirements, and quickly assess the stocking of a retailer's and a competitor's products.
