Liquid level detection device, glass manufacturing device, liquid level detection method, and glass manufacturing method
A liquid level detection device (200) detects the level (L) of molten glass (102) contained within a melting tank (110). The liquid level detection device (200) comprises a camera (210) which captures the image of at least a part of each of the following objects: reference lines (151a, 152a) formed...

| description | A liquid level detection device (200) detects the level (L) of molten glass (102) contained within a melting tank (110). The liquid level detection device (200) comprises a camera (210) which captures the image of at least a part of each of the following objects: reference lines (151a, 152a) formed on the inner wall surface (150) of a glass melting furnace (100); the side wall section (111) of the melting tank (110); and the surface (103) of molten glass (102). The liquid level detection device (200) also comprises an image processing device (220) which processes an image (270P) captured by the camera (210). Thus the liquid level detection device (200) detects the positional relationship in the image (270P) between the reference lines (151a, 152a), the side wall section (111), and the surface (103) and then detects the level (L) on the basis of the detected positional relationship and of the actual positional relationship between the reference lines (151a, 152a). |
