FINISHED SHAPE MANAGEMENT DEVICE AND FINISHED SHAPE MANAGEMENT METHOD AND FINISHED SHAPE MANAGEMENT PROGRAM
To measure a precise finished shape and manage the finished shape.SOLUTION: A finished shape management device comprises: a design data acquisition part to acquire design data of an excavation target area; a reflection light data acquisition part to acquire reflection time data of a laser beam irradiated to four reflectors installed so as to surround the excavation target area and reflection direction data; a laser beam coordinate derivation part to derive laser beam coordinates of a first reflector, a second reflector, a third reflector, and a fourth reflector in a laser beam coordinate system from the acquired reflection time data and reflection direction data; an absolute coordinate derivation part to derive a first, second, third and fourth absolute coordinates by converting the first, second, third, and fourth laser beam coordinates to absolute coordinate system representing coordinate system of the design data; and an excavation state determination part to determine an excavation state of the excavation target area by setting at least one of the first, second, third, and fourth absolute coordinates as a reference.SELECTED DRAWING: Figure 2A
