Trash stirring state detecting device and dust stirring state detecting method

摘要

PROBLEM TO BE SOLVED: To provide a refuse agitated state detection device capable of more accurately detecting the agitated state of refuse in a refuse pit.SOLUTION: A device for detecting an agitated state in a refuse pit in a refuse incineration plant is provided. The device comprises: a photographic camera 12 taking an image of an interior of the refuse pit 1; a gradation unit 24 to which image data obtained by the photographic camera 12 is input and that provides gradation to the image data based on luminance values; an edge extraction unit 25 extracting an edge corresponding to a contour line of a refuse bulk portion by applying an edge extraction filter onto the image data provided with the gradation by the gradation unit 24; fractal-dimension calculation means 14 calculating fractal dimensions of the edge extracted by the edge extraction unit 25 by using box counting; and agitated-state detection means 15 detecting the agitated state of refuse on the basis of the fractal dimensions obtained by the fractal-dimension calculation means 14.
