This papcr presents a 3D-environment nieasurcmcnt systeni for large-scale structure manufacturing. First, a niethod and systeni for generating as-built data are shown. Then a camera calibration method that provides the ncces\ary nieasurenicnt precision in space is introduced, and the nieasurement error is analyzed quantitatively. Finally, the position and orientation of an ob,ject arc measured. and the experimental results are shown to support the theoretical conditions developed here.
