摘要
PROBLEM TO BE SOLVED: To reduce construction periods, and to improve execution precision by easily measuring sections, and evaluating and managing excavation sections and lining sections without complicating work in tunnel excavation constructions.;SOLUTION: A tunnel excavation execution support system includes: a data storage means of tunnel coordinates in targets installed at a plurality of places on wall surfaces of tunnels; a reference data storage means of sections of tunnels; a data storage means of display attributes in comparison sections; a recognition processing means for recognizing positions of targets in three-dimensional measurement data for obtaining scanner coordinates of the targets and tunnel coordinates stored in the data storage means; a coordinates conversion processing means for obtaining coordinates conversion parameters based on the scanner and tunnel coordinates of the targets and converting the measurement data of the scanner coordinates to measurement data of tunnel coordinates; a comparison operation processing means for obtaining comparison section data by performing comparison operation between the measurement data and reference data of the tunnel coordinates; and an output processing means. Information on the comparison sections is output, based on display attribute data 203 and comparison section data 208.;COPYRIGHT: (C)2010,JPO&INPIT
