The camera captures an image of a surrounding environment of a work vehicle and outputs image data indicative of the image. The shape sensor measures a three-dimensional shape of the surrounding environment and outputs 3D shape data indicative of the three-dimensional shape. A controller acquires the image data and the 3D shape data. The controller generates a three-dimensional projection model based on the 3D shape data. The three-dimensional projection model portrays the three-dimensional shape of the surrounding environment. The image is projected onto the three-dimensional projection model based on the image data, thereby generating display image data that represents a display image of the surrounding environment of the work vehicle.

Display system for work vehicle and generation method

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.

Display system for work vehicle

A first capturing image unit mounted on a vehicle body captures an image of surroundings of a work vehicle. A second capturing image unit is disposed above the work implement and captures an image of an area in front of the work implement. A first image generation unit generates, from the image captured by the first capturing image unit, a surroundings composite image, which depicts the surroundings of the work vehicle in a bird's-eye view and is synthesized with a vehicle model depicting the work vehicle. A second image generation unit generates, from the image captured by the second image capturing unit, a work implement composite image, which depicts the area in front of the work implement and is synthesized with the vehicle model and the surroundings composite image. A display unit displays a display image including the vehicle model, the surroundings composite image, and the work implement composite image.
