SURROUNDINGS MONITORING DEVICE FOR SLEWING-TYPE WORK MACHINE

摘要

A slewing-type hydraulic excavator has a plurality of cameras 13 for respectively imaging toward different directions. A view point converting section 21 performs coordinate image data conversion to create overhead view images to look down from an upper position. A composite overhead view image creating section 22 creates a composite overhead view image P arranged around a graphic image of the hydraulic excavator 1. An interference scope indicating section 25 indicates the scope of potential interference on the overhead view image with a surrounding obstacle at respective ground heights at the time of rotating the hydraulic excavator 1. A display image creating section 26 produces the composite overhead view image P together with interference scope which is displayed on a monitor.

1. Surrounding monitoring device for slewing-type work machine which comprises:
plural number of imaging devices, which are mounted on a slewing-type work machine, for taking images respectively toward downwardly inclined and at different directions; a view point converting section for performing coordinate conversion of image data taken from respective imaging devices to make overhead view images to look down from upper position; a composite overhead view image creating section to create a composite overhead view image arranged around symbolized view image of the slewing-type work machine; an interference scope indicating section to indicate on the overhead view image to cause interference with a surrounding obstacle placed according to the ground height at the time of rotating action of the slewing-type work machine; a display image producing section to produce the composite overhead view image together with the interference scope on the display image; and a monitor to display the view image.
