1. NRIAG MX2 Point cloud 3D laser scanner system NRIAG________________ National Research Institute for Astronomy and Geophysics

2. LASER: Basic principles Pulse based Range: Phase base Range: NRIAG________________ National Research Institute for Astronomy and Geophysics

3. Accuracy Accuracy is the proximity of measurement results to the true value. NRIAG________________ National Research Institute for Astronomy and Geophysics Total error = Laser range error + Target error (depends on vehicle speed (2- 15 cm) @15m range, (9-20cm)@50m range, speed 10 km/hr + Navigation trajectory error (5-10cmHz, (10-12cm V) / 10-60m + Base point reference error (control/average solution)

4. Photogrammetry Six cameras Orthorectified and panorama image 360 o NRIAG________________ National Research Institute for Astronomy and Geophysics

5. Integrated Laser and photogrammetry Six cameras NRIAG________________ National Research Institute for Astronomy and Geophysics

6. Analysis Pavement curbs (done in office) Pavement defects (done) Pavement model (grid+autocad find out how xml) Pavement profiles (office) Volume calculations (read document) Classification (office, do some more) Pole detection just colorize and display points with the track Line of sight (understand how it works, usefull for infrastructure) Measurements and dimensions NRIAG________________ National Research Institute for Astronomy and Geophysics
