Work support system
In the work support system equipped with a front work device provided on a hydraulic excavator, an angle sensor that detects the posture information of the front work device, and a controller that provides work support for the hydraulic excavator based on a predetermined and stored work area, a camera, and a touch display capable of specifying any position within the image captured by the camera, the controller configured to extract the image area occupied by the hydraulic excavator from the image captured by the camera and based on the number of pixels in the longitudinal direction of the hydraulic excavator in the extracted image area, the posture information of the hydraulic excavator, and the actual dimensions of the hydraulic excavator, convert the position specified in the image by the touch display into the coordinate values of real space coordinates, and set the work area.
1 . A work support system comprising:
a work device provided on a work machine,
a posture detection device that detects posture information of the work device,
a controller that performs work support for the work machine based on a predetermined and stored work area around the work machine,
an imaging device capable of imaging the appearance of the work machine at the work site, and
an input device capable of specifying any position as an area endpoint within the image captured by the imaging device, wherein
the controller is configured to:
based on a predetermined teacher data, extract the image area occupied by the work machine from the image captured by the imaging device,
based on the posture information detected by the posture detection device and a dimension values of various sections of the work machine which stored in advance, calculate the actual dimensions in the longitudinal direction of the work machine,
based on the number of pixels in the longitudinal direction of the work machine in the extracted image area, and the calculated actual dimensions in the longitudinal direction of the work machine, convert the position of the area endpoint specified in the image by the input device into real space coordinate values, and
set the work area such that the position of the converted coordinate values becomes an endpoint.
2 . The work support system according to claim 1 , wherein
the controller is configured to:
calculate the distance or angle in two directions based on the work machine, based on the coordinates of the position specified by the input device, and
set the range formed using the calculated distance or angle in the two directions as the work area.
3 . The work support system according to claim 1 , further comprising
a position detection device that acquires the position coordinates of the work machine,
a imaging direction detection device that detects an imaging direction of the imaging device, and
a notification device that notifies information to an operator of the work machine, wherein
the controller is configured to:
determine whether the imaging direction by the imaging device is suitable for the position designation by the input device of the work area, based on the relative angle between the position coordinates of the work machine and the imaging direction of the imaging device, and if the controller determines that the imaging direction is not appropriate, notify through the notification device to prompt for an appropriate imaging direction.
4 . A work support system comprising:
a work device provided on a work machine,
