Japanese Patent JP2022157472
Kind Code:
A
Abstract:
To provide a construction machine allowing a boundary of a work area to be displayed at a correct position even upon rotation motion when the boundary of the work area is set on an overview image.SOLUTION: In a construction machine, a hydraulic shovel 1 is provided with: a plurality of cameras 71, 72, 73 attached on a rotation body 3; a controller 34 preventing at least one of a traveling body 4, a rotation body and a work device 2 from deviating from a predetermined work area 59 and generating a composite image 701 viewed from right above the rotation body based on acquired images of the plurality of cameras to generate a boundary line 60 of the work area on the composite image; a monitor 110 displaying the composite image and the boundary line generated by the controller; and a rotational angle sensor 40S detecting a relative angle φ between the rotation body and the traveling body. The controller displays the boundary line on the monitor by correcting a position of the boundary line on the composite image.SELECTED DRAWING: Figure 3
