Abstract: A barcode recognition apparatus and a barcode recognition method. The barcode recognition method includes receiving, from a sensor, a triggering message indicating that a product enters, setting a camera focus on the basis of a barcode in an image of the product obtained using a camera upon receiving the triggering message, obtaining a product image according to the set camera focus, performing preprocessing for extracting a barcode region on the product image, extracting the barcode region from the preprocessed image, and deriving barcode information from the extracted barcode region.

Abstract: A method of registering virtual equipment for a virtual production system includes generating a production system model and a production process model of a virtual factory on the basis of a structure database (DB), a production DB, and an operation DB, extracting a plurality of equipment behavior catalogs (EBCs) regarding a plurality of pieces of virtual equipment used in the virtual factory from an EBC repository on the basis of the production system model, generating and simulating a plurality of equipment processing models on the basis of the plurality of EBCs and the production process model, and generating an EBC set on the basis of the plurality of EBCs when a result of the simulation satisfies a predetermined criterion.
