1 gis & visual computing Innovative low cost technologies and services for Video Mobile Mapping X International Scientific and Technical Conference From Imagery to map: digital photogrammetric technologies September 2010 – Gaeta (Italy)

2 2 Sistemi Avanzati - Roma Applications and Technology Mobile mapping represents a heterogeneous type of sensor integration consisting of navigation sensors as well as imaging sensors, together time synchronized and mounted on a common platform (Schwarz & El-Sheimy, 1996) GPS IMU Odometer Barometer Multiple cameras/video Laser scanner Special sensors (georadar, laser profilometer, etc.)

3 3 Sistemi Avanzati - Roma Applications Asset management and utility inventory (build asset inventories and keep them up to date) Road side equipment : street furniture, road signs, speed limits, road lanes, marking, traffic lights, bus stop, pavement types, vegetation, flood ways, culverts, drains, kerbs, guttering. Verification of existing assets and measurement of asset dimensions Planning and studies (a decision support tool) Follow the evolution in your network: visual inspection and road geometry Organize scheme design and traffic signals, sign replacement program Decision support tool for lane closures and access Creation of a geo referenced imagery database allowing to measure the evolution of the network

4 4 Sistemi Avanzati - Roma Applications Network Operation Visual inspection of network and road geometry Measurement of lane/footpath widths, height clearances and set-backs Graphical aid to works specifications Review existing highway data set, surface condition Planning of responses to events and diversions occurring on the network Follow and control of subcontractors acting in the network Disaster management, planning and response Emergency management plan Adapt intervention planning with data collected after catastrophe Inventory the damages after catastrophe

5 5 Sistemi Avanzati - Roma Technologies Traditional technology Dedicated and specifically fitted vehicles High quality/accuracy and expensive equipments Complex devices require skilled operators Two or more people (driver+ system operators) required during the survey

6 6 Sistemi Avanzati - Roma Innovative technologies Metric panoramic images collection from street level (earthmine) Portable standalone video mapping solution (imajing)

14 14 Sistemi Avanzati - Roma Portable video mapping - Software Tagging environment Mark and qualify regions of interest in any image Comment any picture Export regions of interest with associated xyz position

15 15 Sistemi Avanzati - Roma Portable video mapping - Software High accuracy positioning directly in images through 3D photogrammetry Positionning and attributing tools based on photogrametry for 3D positioning of visible objects in images. Distance between 2 points, height measurement, width measurement, length Photogrametry based on 2 images Position and qualify object in the image

16 Photogrametric principle baseline x,y,zx',y',z'

17 Good base line baseline x,y,zx',y',z'

18 Bad base line baseline x,y,zx',y',z'

19 Bad base line baseline x,y,zx',y',z'

20 Better base line baseline x,y,zx',y',z' Take object the closest possible

21 Preferred zones for pointing & measuring

22 22 Sistemi Avanzati - Roma Portable video mapping - Software Build a network referential Create and edit a network referential in curvilinear abscissa (topology & attributes) Automatically link GPS longitude, latitude, height of survey with linear distance on network Automatically assign a linear position (curvilinear abscissa) to positioned objects. Export surveyed data to your GIS and analysis tools Supported export formats : Shape (ArcGis/ESRI), KML/KMZ (Google Earth), CSV (Excel/OpenOffice)
