The information of the Molten Iron Ladles (MIL) plays an important role in the reasonable scheduling for Overhead Tr aveling Crane (OTC) of steelmaking plant.Currently, to locate the MIL by manual recognition is low efficiency and large workload. For this, a method of the MIL location based on number recognition is proposed in this paper.First, the mathematical morphology is used to locate and extract the character area of the ladles, and then, the vertical projection method is used to segment the character image, finally, the digital character is discerned based on template matching. The resultsshow that the recognition rate reached 96.2% by the above proposed method, which meets the development needs of the data information intelligence in the enterprise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
