Abstract: In a construction method using an excavator that is controlled by manual operation, and an excavator that includes an automatic working-equipment control unit automatically controlling second working equipment on the basis of at least one of a current terrain and a designed terrain of a construction range in a construction site, and a tooth-edge position of the second working equipment, a progress rate that indicates a volume of soil having been excavated by the excavator to a target volume of soil to be excavated by the excavator in the construction range is calculated, and when the progress rate is equal to or larger than a threshold, the excavator stops construction of the construction range, and the excavator takes over the construction of the construction range, from the excavator.

Abstract: A selection unit selects a target image pair which is a processing target from among a plurality of image pairs captured by imaging devices provided in work machines. A stereo measurement unit generates three-dimensional data representing a landform on the basis of the selected target image pair, by using a camera parameter related to the imaging device of the work machine having imaged the selected target image pair.
