SURROUNDINGS MONITORING SYSTEM FOR WORKING MACHINE
A surroundings monitoring system for a working machine is provided by which, even if an image obtained by imaging surroundings of the working machine includes an own vehicle shadow of a complicated shape, it can be prevented that the presence of the own vehicle shadow has an influence on detection of an object existing around the working machine. The surroundings monitoring system for a working machine includes: a monocular camera 6 that picks up an image of the surroundings of the working machine; a characteristic pattern extraction unit 170 that extracts characteristic patterns in the image based on a characteristic amount of the image; a shadow profile extraction unit 40 that extracts a profile of a region, which can be regarded as a shadow of the working machine in the image, based on the characteristic amount of the image; and an object detection unit 180 that detects an obstacle existing around the working machine based on the remaining characteristic patterns obtained by excluding a shadow profile characteristic patterns positioned on the profile extracted by the shadow profile extraction unit from the characteristic patterns extracted by the characteristic pattern extraction unit.
