Abstract: An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.

Abstract: A lift cylinder is attached to a center part of a vehicle body in a vehicle width direction. The lift cylinder causes a work implement to move up and down. A supporting member is attached to the center part of the vehicle body in the vehicle width direction and extends upward from the vehicle body. An imaging device is supported by the supporting member and captures images of a region in front of the vehicle body. A penetrating part is formed in the supporting member. The lift cylinder is disposed through the penetrating part.

Abstract: Provided is a display system, which makes it easy for an operator to accurately grasp a traveling situation of a work vehicle. A front camera captures an excavating blade and topography in front of a crawler dozer. A rear camera captures a fuel tank and a ripper apparatus, and a topography behind the crawler dozer. A display image displayed on a monitor is generated by arranging a front image captured by the front camera and a rear image captured by the rear camera so that the excavating blade in the front image may face the fuel tank in the rear image.

Abstract: A display system includes a work vehicle, a first camera, a computation device, and a display device. The first camera is attached to one side portion of the work vehicle. The first camera has an optical axis inclined downward with respect to a horizontal direction. The first camera captures a first image including a surrounding environment of the work vehicle and a first vehicle body portion. The computation device generates a display image from the first image. The display image includes a surrounding image that depicts the surrounding environment of the work vehicle in a bird's-eye view, and a vehicle image. The vehicle image may combine a vehicle model depicted in the work vehicle and an image of the first vehicle body portion captured by the first camera, or may be an image of the first vehicle body portion. The display device displays the display image.

Abstract: A bulldozer includes a blade disposed in front of a vehicle body. First and second cameras are disposed to the left and right of the vehicle body, respectively. A first optical axis of the first camera faces forward and downward. The first camera overlaps a left crawler belt as seen in a plan view of the bulldozer and is arranged to capture a first image of a gap between a lower edge of the blade and the left crawler belt. A second optical axis of the second camera faces forward and downward. The second camera overlaps a right crawler belt as seen in a plan view of the bulldozer and is arranged to capture a second image of a gap between a lower edge of the blade and the right crawler belt. A display is configured to display the first and second images side-by-side.

Abstract: A bulldozer has a protective structure. The protective structure includes a left pillar portion, a right pillar portion, and a beam portion. The left pillar portion is disposed to the left of a cab and extends in the up-down direction. The right pillar portion is disposed to the right of the cab and extends in the up-down direction. The beam portion is disposed above the cab and couples the left pillar portion and the right pillar portion. A first camera is attached to the left pillar portion and is disposed so that a first optical axis faces forward and downward. A second camera is attached to the right pillar portion and is disposed so that a second optical axis faces forward and downward.
