2. Content 3D laser scanner vs. total station
3D laser scanning methods (processes)
3D laser results
Samples

3. Why is 3D laser scanner better then total station?
Higher detail level

4. Why is 3D laser scanner better then total station?
Additional posibilities

5. Why is 3D laser scanner better then total station?
Higher productivity:
Automatic inclination
High measurement rate ~ pt/s
Redundant data, let’s avoid re-measurements
Is possibility to create automatically:
3D surface
Contour lines
Object outlines, sections

6. Why is total station better then 3D laser scanner?
Weight
~14kg ~5kg

7. Wherewith is total station similar to 3D laser scanner?
Both need direct see line to measured object

8. Measurement methods Scanning of selected area
Scanning and taking image of selected area
Scanning of selected point

9. Measurement methods From One station (point)
Travers or traverse network
Use retro reflectors for station registration
Use GPS for station registration (Stop & go or Mobile scan)

10. Live DEMO Riegl LMS-Z420i Scan speed 12000 points per second;
Measurement from 2m to 1km;
Accuracy 1cm (at 50 m distance);

11. Possible results Point cloud (Intensity, True Color, one color)
3D surface with or without texture
Panoramic and ortophoto images
2D ir 3D drawing
Volume, area, verticality and change evaluation
Animation
