Introduction Why Terrestrial Laser Scan Urban Plan Application DemonstrationSummary & Outlook

What is Terrestrial Laser Scan

Why Terrestrial Laser Scan

Increasing in the request for 3D digital city model

Need for more precise and real 3D model

The demand for more detailed and realistic models to improve participatory in Urban Planning

Productivity:

• Up to 50 km per day in urban areas• Up to 100 km per day in extra-urban areas• 1 day post-processing for every 5 days of data capture with geo referenced images and point clouds• 0,5 to 2 hours work for data input per kilometer to carry out a full GIS database

Results and deliverables:

• Routes • Pavements• Vertical signs• Traffic markings (automatically detected by the reflectance)• Sidewalks and building facades• Slopes• Retaining walls and shoulders• Tunnels and bridges• guard rails

Urban Plan Application

• Point cloud overlap on images• Stereoscopic Photogrammetry• Measurements can be taken by snapping on laser points• Cross section of the infrastructure • Export point clouds and cross- sections in CAD format• Geo database of all road information

• TRANSVERSAL PROFILES AND MEASUREMENTS PERPENDICULAR TO THE ROAD !!!

FARO LS 880 mounted upside down to capture road surface

Camera units which capture 6 color images every 3 travelled meter

Odometer – Sensor to measure driving speed and distance travelled

Helical Scanning

Advantage 2 : very homogenous Scanlines

Advantage 1 : 6 – 20 x higher collectionspeed than Stationary Scanning

Summary & Outlook • Terrestrial Laser scan necessary tools role in Road Scanning

• The outcome result of different projects show the suitability of the Terrestrial LS in Road Scanning

• The demand for detailed 3D city models can be well done through Terrestrial LS

• Urban Planner should consider the new Terrestrial LS applications and profit from it
