As-build survey of undergrounds tunnels

We have scanned next sections of tunnels of second line Warsaw underground. We have measeured northern tunnels among C10, C11, C12 and C13, C14 stations. Overall lenght of this tunnels is 1840m.

We are scanning tunnel layer in order to determine the deviation of the position of the project. We have scanned a total of more than 5.0 km of tunnels. The accuracy of calculating the position of the point in the cloud does has not exceeded 7 mm.
