1. A method for lost asset management using photo-matching, the method comprising:
capturing, by an imaging device, a lost asset image corresponding to a lost asset;
generating, by applying a feature extractor model to the lost asset image, a lost asset descriptor that represents features of the lost asset image;
storing the lost asset descriptor and the lost asset image in an asset database, wherein the asset database includes known asset descriptors and corresponding known asset images;
performing, by a visual search engine, a nearest neighbor search within the asset database to determine a respective metric distance between the lost asset descriptor and at least some of the known asset descriptors;
determining, by the visual search engine, a ranked list of known assets corresponding to the lost asset, wherein the ranked list of assets is prioritized based on the respective metric distance between the lost asset descriptor and the at least some of the known asset descriptors;
displaying, at a user interface, the ranked list of known assets for viewing by a user;
receiving, from the user, an indication that no known asset listed on the ranked list of known assets corresponds to the lost asset;
re-performing, by the visual search engine, the nearest neighbor search within the asset database by including (i) an asset location, (ii) an asset routing, (iii) an asset size, (iv) an asset pallet type, (v) an asset date, or (vi) an asset delivery status for at least some of the known assets to determine a respective new metric distance between data stored in the asset database representing the lost asset and the at least some of the known assets;
determining, by the visual search engine, a new ranked list of known assets corresponding to the lost asset, wherein the new ranked list of known assets is prioritized based on the respective new metric distance between the data stored in the asset database representing the lost asset and the at least some of the known assets; and
displaying, at the user interface, the new ranked list of known assets for viewing by the user.
