Abstract: A calibration system includes at least a pair of imaging devices in a work machine having a working unit that image an object; a position detector detecting a position of the working unit; and a processing unit that, by using first position information about a predetermined position of the working unit captured by the imaging devices, second position information about the predetermined position detected by the position detector in an attitude of the working unit taken when the imaging devices image the predetermined position, and third position information about a predetermined position outside the work machine, imaged by the imaging devices, obtains information about a position and an attitude of the imaging devices, and transformation information used for transforming a position of the object imaged by the imaging devices from a first coordinate system to a second coordinate system.

Abstract: A construction management system includes: an object detecting unit mounted on a work machine and configured to detect an object in a construction site and output information on the object; a shape detecting unit configured to output shape information indicating a three-dimensional shape of the object by using the information on the object detected by the object detecting unit; an information attaching unit configured to attach, to the shape information, time information indicating a time when the object is detected; and a management device configured to generate current state information on the construction site on the basis of the shape information to which a latest piece of the time information is attached.
