5. Conclusion
In this paper, the design of a mobile mapping system is
presented. Integration the GPS, INS and stereo cameras
on a moving platform enable us to efficiently collect huge
amounts of digital data for GIS application. Every object
which is seen on the stereo images can be positioned in a
global coordinate system together with its attributes. All
data collected can be transferred into common GIS
systems. Data collected using the GPSVision meets the
requirements of most engineering applications. Several
project have been completed successfully.
Automatic extraction of the features is a very important
issue for mobile mapping application, it will greatly
improve the data extraction procedure. Integrating
other hardware, like a laser range finder, will bring the
new abilities of the mobile mapping system. These are
two major development in the future.
