Abstract
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.
