  • Patent number: 11772556
    Abstract: A work vehicle includes work equipment having a work tool and a support member supporting the work tool. A display control system controls a display device provided outside the work vehicle. The display control system includes a captured image acquisition unit, a supplementary image acquisition unit, a display image generation unit, and a display control unit. The captured image acquisition unit acquires a captured image captured by an imaging device mounted on the work vehicle. The supplementary image acquisition unit acquires a supplementary image representing information related to the work vehicle. The display image generation unit generates a display image in which the supplementary image is disposed in an area where a side surface of the support member can be shown in the captured image. The display control unit outputs a display signal in order to display the display image on the display device.

  • Publication number: 20230291989
    Abstract: A captured image acquisition unit acquires a captured image showing work equipment from a camera provided at a work machine. A blade edge shadow generation unit generates a blade edge shadow obtained by projecting a blade edge of the work equipment on a projection surface toward a vertical direction. A display image generation unit generates a display image obtained by superimposing the captured image, the blade edge shadow, a left line, and a right line. The left line passes through a left end of the blade edge shadow and extends in a front-and-rear direction of the work equipment along the projection surface. The right line passes through a right end of the blade edge shadow and extends in the front-and-rear direction of the work equipment along the projection surface. A display control unit outputs a display signal for displaying the display image.
