REFUSE AGITATED STATE DETECTION DEVICE AND REFUSE AGITATED STATE DETECTION METHOD

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. 【課題】ごみピット内でのごみの攪拌状態をより正確に知ることができるごみ攪拌状態検出装置を提供する。【解決手段】ごみ焼却設備におけるごみピット１内の攪拌状態を検出する装置であって、ごみピット内を撮影する撮影カメラ12と、この撮影カメラにて撮影された画像データを入力するとともに輝度値に基づき階調化する階調化部24と、この階調化部で階調化された画像データに対してエッジ抽出用フィルタを用いてごみの塊部分の外形線に対応するエッジを抽出するエッジ抽出部25と、このエッジ抽出部で抽出されたエッジのフラクタル次元をボックスカウント法を用いて演算するフラクタル次元演算手段14と、このフラクタル次元演算手段で求められたフラクタル次元に基づきごみの攪拌状態を検出する攪拌状態検出手段15とから構成したもの。【選択図】図３
