작업 기계의 주변 감시 장치는, 작업 기계의 주위 영상을 촬영하는 복수의 촬영 장치와, 복수의 촬영 장치의 각 촬영 화상을 상방 시점 화상으로 변환하고, 그것들에 기초하여 작업 기계 주위의 부감 화상을 생성하는 부감 화상 생성부와, 부감 화상 표시 영역에 부감 화상을 표시하는 표시부를 구비하고, 부감 화상 생성부는, 복수의 촬영 장치에 포함되는 제1 촬영 장치의 촬영 화상에 대한 제1 상방 시점 화상과, 복수의 촬영 장치에 포함되는 제2 촬영 장치의 촬영 화상에 대한 제2 상방 시점 화상과의 중복 영역에서의 부감 화상을 생성할 때, 가상 감시 대상의 높이에 기초하여, 제1 상방 시점 화상이 표시되는 제1 영역 및 제2 상방 시점 화상이 표시되는 제2 영역 중 적어도 한쪽과, 제1 및 제2 상방 시점 화상에 기초하는 합성 표시 화상이 표시되는 제3 영역을 설정한다. The periphery monitoring device for a work machine, includes: a plurality of imaging devices that each capture an image of surroundings of the work machine; an overhead view image generating unit that converts the image captured by each of the plurality of imaging devices into an upper view-point image, and generates an overhead view image of the surroundings of the work machine based upon upper view-point images; and a display unit that displays the overhead view image in an overhead view image display region, wherein: when generating an overhead view image of an overlap region of a first upper view-point image relating to the image captured by a first imaging device included in the plurality of imaging devices and a second upper view-point image relating to the image captured by a second imaging device included in the plurality of imaging devices: the overhead view image generating unit, based upon a height of a virtual monitoring target, sets at least one of a first region in which the first upper view-point image is displayed and a second region in which the second upper view-point image is displayed, and also sets a third region in which a composite display image based upon the first and second upper view-point images is displayed.
