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.

Construction method and construction system

A control apparatus for work machines includes a position designation reception unit configured to identify designation of a position with respect to a state image displayed on a display panel and a screen control unit configured to perform screen control according to an image displayed at the position that has been identified, among partial images constituting parts of the state image.

Reproduction apparatus, analysis assistance system, and reproduction method for synchronizing reproduction of a construction machine model

A topographic information transmission device which is provided in a construction site includes an image data reception unit that receives a plurality of pieces of image data in which a landform of the construction site is captured, a three-dimensional data creation unit that creates three-dimensional data of the construction site on the basis of the plurality of pieces of image data, an amount-reduction processing unit that performs an amount reduction process of reducing a total data amount of the created three-dimensional data, and a topographic information transmission unit that transmits amount-reduced three-dimensional data having undergone the amount reduction process to an information providing device.

Topographic information transmission device, construction management system, and topographic information transmission method

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.

Construction management device and construction management method

An acquisition unit acquires design data which is three-dimensional data indicating a terrain. A gradient identification unit identifies a gradient of each of the plurality of polygons configuring the design data. An attribute setting unit sets an attribute for each of the plurality of polygons based on the gradient.
