Surrounding area monitoring device for work vehicle

摘要

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.

1. A work vehicle surrounding area monitoring device comprising:
an imaging unit mounted on a work vehicle, the imaging unit being configured to capture an image of a region of a surrounding area of the work vehicle to obtain image data; a bird's-eye view image creating unit configured to create a bird's-eye view image of the surrounding area of the work vehicle by projecting the image data on a virtual projection plane; a display unit configured to display the bird's-eye view image; and a traveling state determining unit configured to determine whether the work vehicle is in a traveling state or a stopped state, wherein, the bird's eye view image creating unit selects between creating the bird's eye view image using a first virtual projection plane and creating the bird's eye view image using a second virtual projection plane in response to a determination result of the traveling state determining unit, such that when the work vehicle is in the stopped state, the bird's-eye view image creating unit uses the first virtual projection plane to create the bird's-eye view image, at least an outer edge portion of the first virtual projection plane having a shape that increases in height from a 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 uses the second virtual projection plane to create the bird's-eye view image, at least an outer edge portion of the second virtual projection plane having a shape with a uniformly flat height from the ground surface, and the display unit switches between displaying the bird's eye view image using the first virtual projection plane and the displaying the bird's eye view image using the second virtual projection plane in response to the determination result of the traveling state determining unit.
