Display device, shovel, information processing apparatus
A display device displays information image related to an excavation work, in an ambient environment image in a view of a work area or an attachment viewed from a shovel, or in a field of view of an operator viewing the work area or the attachment from the shovel. The shovel may include the display device. A management device may include a display apparatus, a communication device which communicates with the shovel, and a remote control device operated by a user to remotely control the shovel via the communication device.
1. A display system for a shovel having a slewing upper structure and an imaging device mounted on the slewing upper structure, the display system comprising:
a display device configured to display an information image for assisting an excavation work of the shovel; and
a controller configured to selectively display the information image selected from a plurality of information images on the display device in response to an input, wherein
the controller controls the display device to display the selected information image in an ambient environment image in a view of a work area viewed from the shovel, or in a field of view of a user operating the shovel,
the plurality of information images include a control limit related to a machine control function which performs the excavation work regardless of an operation performed by the user, and at least one of work information related to a machine guidance function which guides a manual operation of the shovel, and a plan of the excavation work,
the control limit indicates a three-dimensional range reachable by a tip end of an attachment of the shovel, in a state visible by the user viewing an ambient environment of the shovel, and
the plan of the excavation work includes an order and a type of work to be performed on each of a plurality of scheduled excavation targets.
2. The display system as claimed in claim 1 , wherein the imaging device includes a plurality of sensors or cameras mounted on the slewing upper structure at positions to capture images in front, rear, left, and right of the slewing upper structure.
3. The display system as claimed in claim 2 , wherein the controller controls the device to display an ambient environment image based on images captured by the plurality of sensors or cameras, and superimpose the selected information image on the displayed ambient environment image.
4. The display system as claimed in claim 3 , wherein the ambient environment image includes the images captured by the plurality of sensors or cameras capturing images in front, rear, left, and right of the slewing upper structure.
5. The display system as claimed in claim 1 , wherein the display device includes a wearable device configured to display the selected information image on a transmission type projection surface in the field of view of the user viewing the work area from the shovel.
6. The display system as claimed in claim 1 , wherein the information image includes an information image of an operating plane of an attachment of the shovel displayed three-dimensionally and including areas having different levels of work efficiencies for the excavation work, and the different levels of the work efficiencies are indicated using gradation or numerical values.
7. The display system as claimed in claim 1 , wherein the information image includes an information image which guides an operation of an attachment of the shovel.
8. The display system as claimed in claim 1 , wherein the display device is configured to be portable by the user.
9. A shovel comprising:
a cabin; and
the display system according to claim 1 ,
wherein the display device is provided inside the cabin.
10. An information processing apparatus comprising:
the display system according to claim 1 ;
a communication device configured to communicate with the shovel; and
an operating device, operated by the user, and configured to remotely operate the shovel via the communication device.
11. The display system as claimed in claim 1 , wherein the controller controls the display device to superimpose the selected information image on
an image of a work area imaged by the imaging device and displayed on a non-transmission type projection surface or display, or
the image of the work area visible on a transmission type projection surface or display in a field of view of a user operating the shovel.
12. A shovel comprising:
a cabin; and
the display system according to claim 11 ,
wherein the display device is provided inside the cabin.
13. An information processing apparatus comprising:
the display system according to claim 11 ;
a communication device configured to communicate with the shovel; and
an operating device, operated by the user, and configured to remotely operate the shovel via the communication device.
