Abstract

A device for monitoring the surrounding area is provided in a self-propelled working machine, which is provided with a working means, and an operation means at a position near a driver's seat of a revolving structure and performs predetermined work, and monitors the area around the working machine, the device having a configuration provided with: a plurality of cameras which are provided in the revolving structure, two cameras each being installed such that parts of viewing fields thereof overlap each other; an image transform means which generates virtual viewpoint images by viewpoint-transforming camera images acquired by the respective cameras such that the camera images become top-view images; an image synthesis means which sets, on a monitor, the display regions of the virtual viewpoint images captured by the respective cameras and displays the respective virtual viewpoint images in the display regions; and a display form change means which changes the boundary positions between the display regions of the respective virtual viewpoint images.

Description

Technical field [0001] The present invention relates to a surrounding monitoring device of a working machine installed in a working machine composed of a hydraulic excavator or the like in order to ensure the safety of the machine's work. Background technique [0002] As an example of a work machine, for example, a hydraulic excavator is a self-propelled work machine and has a traveling body having a crawler type or wheel type traveling unit. A rotating body is provided on the traveling body by means of a rotating device. The rotating body is provided with a working unit for digging sand and soil. The working unit is provided with a boom connected to the rotating body so as to be able to move upward and downward, and a boom connected to the front end of the boom so as to rotate in the up and down direction. An arm, a bucket for excavating sand and soil, is used as an attachment, and is connected to the tip of the arm by a link mechanism, and these components constitute a multi-j...
