Abstract: Provided is a technology to properly display information onto a projection surface without depending on a distance image sensor, and directly project a wide range of information other than a survey setting point onto a construction site. A system includes: a projector including an inclination sensor and at least one reflector ; a measuring device configured to measure a position of the reflector; a means having surface information; and a means configured for setting a distance difference between a projection surface onto which the surface information is projected and the measuring device in a normal direction, wherein the measuring device measures the reflector, and the surface information adjusted according to the distance difference in the normal direction is projected onto the projection surface.

Abstract: Data management to reflect an actual construction status in design is realized. In order to achieve the object, a management system includes a design database recording, with respect to members of a construction object, design data of at least member IDs, member coordinates, member shapes, a measurement database recording measurement data of the construction object, a starting point member selecting unit configured to select a starting point member from the design database, a measurement information selecting unit configured to select the measurement data corresponding to the starting point member from the measurement database, and an actual status model creating unit configured to create an actual status model with respect to the starting point member by performing shape correction of a design model of the starting point member created from the design database by using the measurement data.

Abstract: A management system includes a design database of construction members, a measurement database of the construction members, a construction database recording construction data of the construction members, a construction member selecting unit, a peripheral member selecting unit, a model creating unit configured to create a design model of the construction member and a measurement model of the peripheral member, a corrected model creating unit configured to create a design corrected model by synthesizing the design model and the measurement model, and a corrected construction plan creating unit configured to select a construction designated member based on the design corrected model, and record, with respect to the construction designated member, coordinates and a shape of the design corrected model as construction designated member coordinates and a construction designated member shape, and construction content of the construction designated member as construction inspection content, in a corrected construction plan database.
