1. A construction management system comprising: a work machine, operated by an operator, with at least one pair of image devices; a geological data input unit including a computer keyboard or a touch panel; a detection processing device comprising: a computer system including a processor, a storage device and an input/output interface, the detection processing device including: a two-dimensional image data acquisition processor unit and a three-dimensional data acquisition processor unit; the two-dimensional image data acquisition processor unit, being capable of performing data communication, configured to acquire two-dimensional image data of a work target captured by the imaging device; the input unit configured for operator input of geological data including a boundary between geologies to the two-dimensional image data by the operator inputting, at a boundary position of the geologies in the two-dimensional image data of the work target, boundary data indicating the position of the boundary in the data, the boundary data being included in the geological data; the three-dimensional data acquisition processor unit acquires three-dimensional data including the boundary between geologies based on a pair of pieces of two-dimensional image data of the work target captured by the at least one pair of image devices including the two-dimensional image data; and an identifier adding processor unit configured to add an identifier to the two-dimensional image data to which the geological data including the boundary between geologies is input; wherein the geological data is data input by the operator through the input unit, and includes at least boundary data between a first geological area and a second geological area having a different geology from the first geological area, data about a first geology indicating a geology of the first geological area, and data about a second geology indicating a geology of the second geological area, and the data about the first and second geologies including at least a rock quality and stiffness of ground and thus the three-dimensional data including the boundary data between the geologies is acquired by extracting two-dimensional image data to which the identifier is added having based on the operator input geological data and by performing image processing, whereby the three-dimensional data of a boundary between geologies are efficiently acquired.
