Abstract
A display system includes: an image data acquisition unit that acquires a front image and a side image captured by an imaging device mounted on a work machine having a swing body swinging about a swing axis and working equipment supported by the swing body, the front image including at least an image in a front direction with respect to the swing axis, the side image including at least an image in a lateral direction to the swing axis, the lateral direction being orthogonal to the front direction; and a display control unit that displays the front image and the side image acquired by the image data acquisition unit on a display device existing outside the work machine.
Claims6
A display system comprising:
- an image data acquisition unit that acquires a front image and a side image captured by an imaging device mounted on a work machine having a swing body swingably supported by a travel body about a swing axis and working equipment supported by the swing body, the front image including at least an image in a front direction with respect to the swing axis, the front image being captured by a front camera of the imaging device;
- and
- the side image including at least an image in a lateral direction with respect to the swing axis, the lateral direction being orthogonal to the front direction, the side image being captured by a side camera of the imaging device;
- a display device existing outside the work machine;
- a remote control device existing outside the work machine, the remote control device being operated by an operator sitting on a control seat;
- and
- a display control unit that displays the front image and the side image acquired by the image data acquisition unit on a display screen of the display device,
- wherein the work machine carries out a swing excavation and loading work in which the work machine operates the working equipment and the swing body to load an excavated object on a loading target after an excavation work in which the work machine excavates an excavation object with the working equipment,
- in the swing excavation and loading work, the side image includes a captured image of the work machine in a swing direction and a captured image in a direction opposite to the swing direction, and
- the display control unit displays the side image with the front image on the display device, and
- the side camera includes a first side camera that captures a left direction of the swing body and a second side camera that captures a right direction of the swing body, and
- a second side image captured by the second side camera includes an image of the working equipment, and
- an optical axis of an optical system of the front camera and an optical axis of an optical system of the side camera are arranged in a common predetermined plane.

A remote control system comprising:
- an imaging device that is mounted on a work machine having a swing body swingably supported by a travel body about a swing axis and working equipment supported by the swing body and captures a front image including at least an image in a front direction with respect to the swing axis, the front image being captured by a front camera of the imaging device;
- and
- a side image including at least an image in a lateral direction with respect to the swing axis, the lateral direction being orthogonal to the front direction, the side image being captured by a side camera of the imaging device;
- a display device existing outside the work machine;
- and
- a remote control device existing outside the work machine and communicates with the work machine, the remote control device being operated by an operator sitting on a control seat,
- wherein the remote control device comprises:
- an image data acquisition unit that acquires the front image and the side image from the imaging device;
- and
- a display control unit that displays the front image and the side image acquired by the image data acquisition unit on a display screen of the display device,
- wherein the work machine carries out a swing excavation and loading work in which the work machine operates the working equipment and the swing body to load an excavated object on a loading target after an excavation work in which the work machine excavates an excavation object with the working equipment,
- in the swing excavation and loading work, the side image includes a captured image of the work machine in a swing direction and a captured image in a direction opposite to the swing direction, and
