Abstract:
1. A hydraulic shovel calibration device for calibrating parameters in a hydraulic shovel, the hydraulic shovel including a vehicle body, a work implement including a boom swingably attached to the vehicle body, an arm swingably attached to the boom, and a work tool swingably attached to the arm, an angle detection unit configured and arranged to detect a swing angle of the boom with respect to the vehicle body, a swing angle of the arm with respect to the boom, and a swing angle of the work tool with respect to the arm, and a current position computation unit configured to compute a current position of a working point included in the work tool based on a plurality of parameters that indicate dimensions and the swing angles of the boom, the arm, and the work tool, the hydraulic shovel calibration device comprising: an input unit configured and arranged to input working point position information indicating a position of a boom pin and coordinates of the working point at a plurality of positions which are measured by an external measurement device; and a calibration computation unit configured to compute calibration values of the parameters based on the working point position information input into the input unit.
