PROBLEM TO BE SOLVED: To provide a boom collision avoidance system for a work machine, which eliminates the need for manual setting of a work limiting range and which is able to start work promptly for any obstacle having a complicated shape and safely even if there are any people nearby.SOLUTION: The boom collision avoidance system for a work machine comprises: a video camera 10 provided at a leading end 4t of a boom 4 of a crane body 1; an image processing part 20 that processes an image photographed by the video camera 10, and calculates a separation distance T between the boom 4 and an obstacle S on the basis of the result of the image processing; and a collision avoidance control part 30 that exerts collision avoidance control for avoiding collision of the boom 4 with the obstacle S on the basis of information about the separation distance T output from the image processing part 20.

    【課題】人為的な作業規制範囲の設定が不要であり、複雑形状の障害物に対しても迅速に且つ近傍に人がいても安全に作業を開始することができる作業機用ブーム衝突回避装置を提供する。【解決手段】この作業機用ブーム衝突回避装置は、クレーン本体1のブーム4の先端4tに設けられたビデオカメラ10と、ビデオカメラ10で撮影した画像を画像処理するとともに、その画像処理の結果に基づいてブーム4と障害物Sとの離隔距離Tを算出する画像処理部20と、画像処理部20から出力された離隔距離Tの情報に基づいてブーム4と障害物Sとの衝突を回避する衝突回避制御を行う衝突回避制御部30とを備える。【選択図】図1
