INTERFERENCE PREVENTION DEVICE FOR CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To prevent wrong detection of a movable portion having no possibility of interference as an interference object without narrowing a detection range of a distance sensor.SOLUTION: A region removal section 121 determines a coordinate region indicating a region in distance image data of a boom 15 by using posture information acquired by an acquisition section 100, and removes pixel data constituting the determined coordinate region from the distance image data. An interference determination section 122 detects an interference object that is a work device 4 or an object held by the work device 4 by using the distance image data from which the pixel data constituting the coordinate region has been removed, and determines an interference risk of the detected interference object with a driving cab 31. When the interference determination section 122 determines that there is the interference risk, an interference prevention section 123 at least issues a warning to an operator or restricts an operation of the work device 4.SELECTED DRAWING: Figure 2
【課題】距離センサの検出範囲を狭くしなくても、干渉のおそれがない可動部が、干渉対象物として誤検出されることを防止する。【解決手段】領域除去部１２１は、取得部１００により取得された姿勢情報を用いて、ブーム１５の距離画像データ内での領域を示す座標領域を決定し、決定した座標領域を構成する画素データを距離画像データから除去する。干渉判定部１２２は、座標領域を構成する画素データが除去された距離画像データを用いて、作業装置４又は作業装置４の把持物である干渉対象物を検出し、検出した干渉対象物の運転室３１への干渉の危険性を判定する。干渉防止部１２３は、干渉判定部１２２により干渉の危険性が有ると判定された場合、オペレータへの警告及び作業装置４の動作制限の少なくとも一方を行う。【選択図】図２
