2

Goal: complete tunnel documentation in Road tunnel

Preparation:Survey a number of tripods

3

Standard signal height in all instruments and accessories

Scanning from each known tripodusing minimum 1 reference on another

known tripod

AGENDA:

•On-site work

P i•Processing

•Deliveries

•Compare SOTA

•Case studies

•Conclusion

Registration with fixed position

5

Clean scan to get pure tunnel data

Cleaned scan, pure tunnel data

6

5 cleaned scans

Import scan to RRT

7

Choose *.fls and point distance

Resulting reduced point cloud in RRT

8

Define theoretical tunnel, x&y line

Define teoretical tunnel, Profile

16

Conclusion• 3D scanning is much faster

• Same accuracy in tunnel data

M lti l f d t• Multiple use of same data

• Thank You for your attention!
