“Riegl” 3D laser scaner Egidijus Žilinskas
Content 3D laser scanner vs. total station 3D laser scanning methods (processes) 3D laser results Samples
Why is 3D laser scanner better then total station? Higher detail level
Why is 3D laser scanner better then total station? Additional posibilities
Why is 3D laser scanner better then total station? Higher productivity: Automatic inclination High measurement rate ~12 000 pt/s Redundant data, let’s avoid re-measurements Is possibility to create automatically: 3D surface Contour lines Object outlines, sections
Why is total station better then 3D laser scanner? Weight ~14kg ~5kg
Wherewith is total station similar to 3D laser scanner? Both need direct see line to measured object
Measurement methods Scanning of selected area Scanning and taking image of selected area Scanning of selected point
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)
Live DEMO Riegl LMS-Z420i Scan speed 12000 points per second; Measurement from 2m to 1km; Accuracy 1cm (at 50 m distance);
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
