Work support system

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.
