  • Patent number: 10060098
    Abstract: In a method of displaying a dead zone of a construction machine, actual images with respect to omnidirectional views of a cabin in the construction machine may be obtained. A virtual image with respect to the dead zone generated by a working tool, which may be connected to the cabin, may be obtained from the actual images. The virtual image may be displayed on a monitor in the cabin. Thus, a worker in the cabin may accurately acknowledge whether a man or a fixture may exist or not in a region in front of a rotation direction of a boom by seeing the virtual image. Thus, a negligent accident caused by the rotation of the boom may be prevented.

  • Publication number: 20140118533
    Abstract: According to the present invention, an operational stability enhancing device for construction machinery is provided. The operational stability enhancing device for construction machinery includes: a plurality of cameras configured to capture surrounding images of construction machinery; a plurality of sensors configured to detect an obstacle located in the surrounding area of the construction machinery; a monitor configured to display the surrounding images captured by the plurality of cameras; and a control unit configured to, in a case where a detected object is detected in a surrounding area of a moving path by the sensor, and the detected object is an avoidance processing target, display an image of the captured detected object on a monitor through screen conversion or change the image of the captured detected object so as to be easily recognized by an operator when the construction machines approaches the detected object.
