    • The present invention relates to a method for generating an as-built drawing of a building using a 3D laser scanner. The method comprises the steps of: (a) measuring a plurality of reference points positioned inside and outside a building to obtain absolute coordinates; (b) scanning the building using a 3D laser scanner, based on the absolute coordinates of the reference points to generate point data; (c) attaching the point data to each point of the building generated by the 3D laser scanner to match into a point data; and (d) extracting 2D drawing information from the 3D point data. According to the present invention, an accurate as-built drawing of a building can be made by scanning the inside of the building corresponding to each point using a 3D laser scanner, extracting point data, and making a 2D drawing, which is the as-built drawing of the building, using the point data.

    • PURPOSE: A quick ambiguity integer decision method and a position decision method are provided to use the method capable of deciding an ambiguity integer quickly and accurately through a reference point and a GPS(Global Positioning System) reception of a position to measure in a GPS carrier phase relative positioning mode, thereby provide the quick and accurate position information through a fast position deciding in a GPS. CONSTITUTION: In order to set an ambiguity integer decision in a phase relative positioning mode, a railway route is classified into a predetermined section according to the railway route information(S100). A pre-installed GPS reception is installed in a predetermined reference point and a train running through the railway route, respectively, and each of the GPS signal in which the GPS reception received from each of the installed reception is received(S102). Each of the received GPS signal and the relative positioning of a point that will be measured are performed(S104). By using the measured relative position and the railway route information classified into the predetermined section, an ambiguity integer to calculate an absolute position in the GPS is determined(S106).
