Abstract
A work vehicle surrounding area monitoring device includes an imaging unit, a bird's-eye view image creating unit, a display unit and a traveling state determining unit. When the work vehicle is in the stopped state, the bird's-eye view image creating unit is configured to use a first virtual projection plane to create the bird's-eye view image, and at least an outer edge portion of the first virtual projection plane has a shape that increases in height from the ground surface as a distance from the work vehicle increases. When the work vehicle is in the traveling state, the bird's-eye view image creating unit is configured to use a second virtual projection plane to create the bird's-eye view image, and at least an outer edge portion of the second virtual projection plane has a shape having a uniformly flat height from the ground surface.
