Document Type and Number:
Japanese Patent JP2023172123
Kind Code:
A
Abstract:
To provide a molten metal occupancy measurement device which is capable of obtaining the occupancy of an image region with molten metal imprinted at more high precision, and a method therefor.SOLUTION: A molten metal occupancy measurement device D comprises an imaging unit 1 of creating a color image looked down at the inside of a container of molten metal, a first region extraction unit 24 of obtaining a slag image region of slag and a molten metal candidate image region which is a candidate for the molten metal based on a green image of a green component in the color image, a second region extraction unit 25 of obtaining the molten metal image region of at least one of the slag and the molten metal in the slag image region and the molten metal candidate image region obtained at the first region extraction unit 24 based on a red image of a red component in the color image and an occupancy treatment unit 26 of obtaining the occupancy of the image region with the molten metal imprinted as a naked molten metal area ratio based on the obtained slag molten metal image region.SELECTED DRAWING: Figure 1
