Simulink and Motion Cuing

Hello,
I am interested in integrating a laser scan from a Faro 3D x330 scanner of a stretch of road with buildings, with a motion cuing program. The intent is to recreate a real environment synthetically, then access the environment virtually in a simulator, similar to the way race tracks are now scanned for research and development of vehicles. I am looking to enter the environment in a vehicle that reacts the actual road conditions while surrounded by the visual scenery from the laser scan. It is possible to fly through the scan for the architectural construction benefits, but I am looking to travel through it the same way, just in a vehicle, or simulator.
Has anyone ever accomplished this? Is it possible? Would it take a tremendous amount of time? The scan can be performed and loaded fairly quickly.
I appreciate the input.

Hi,
AFAIK, laser scan point clouds can be used for virtual model alingment, not yet for complete virtual (or CAD) model creation.
If you want to use some virtual reality model in connection with a dynamical model, it is important that the dynamical model uses the same, usually parametrized, model for its internal computations.
Example - a vehicle dynamics model contains also a "road model" in order to be able to keep the vehicle on the road during the simulation (there is also a "driver model") to achieve that. The road can be (in a simple case) defined by the road centerline, width and lateral inclination in every point on the centerline.
Your task could be accomplished perhaps as follows:
- Recognize between the "road surface" and the "rest" - road environment / background parts of the point cloud
- Fit the "road surface" to some parametric model that can be used by your dynamic model
- In the virtual reality environment, use the fitted parametric model together with the unprocessed "rest of the point cloud" as the environment
Good luck,
Jan
