Zusammenfassung:To provide an object detection system for a work machine capable of inexpensively detecting an object in a blind spot.SOLUTION: An object detection system for a work machine that detects an object existing around a work machine (10) having an upper revolving body (12) mounted on a lower traveling body (11) via a rotating mechanism comprises: a camera (20CB) provided on an upper part of the upper revolving body, including the ground around the work machine as an imaging area (21CB), and imaging the imaging area to generate a captured image; a light (25CB) for emitting light toward the ground (22CB) included in the imaging area; and a controller (110) for detecting objects around the work machine based on the captured image, wherein an image feature quantity of the captured image is analyzed to detect the object based on whether a shadow (92CB1) of the object (91CB1) existing on an optical path from the light to the ground included in the imaging area appears in the captured image.SELECTED DRAWING: Figure 5 【課題】死角にある物体をより安価に検知できる作業機械の物体検知システムを提供する。【解決手段】旋回機構を介して下部走行体(11)に搭載される上部旋回体(12)を備える作業機械(10)の周囲に存在する物体を検知する作業機械の物体検知システムは、上部旋回体の上部に備えられ、作業機械の周辺の地面を撮像領域(21CB)として含み、当該撮像領域を撮像して撮像画像を生成するカメラ(20CB)と、撮像領域に含まれる地面(22CB)に向かって光を発するライト(25CB)と、撮像画像に基づいて作業機械の周辺の物体を検知するコントローラ(110)とを備え、撮像画像の画像特徴量を解析し、ライトから撮像領域に含まれる地面までの光路上に存在する物体(91CB1)の影(92CB1)が撮像画像に映っているかに基づき、物体を検知する。【選択図】図5
