Real time top-view

Hi,
We have calibrated 4 cameras for a surround view set following the calibration guide.
Now we would like to visualize a real time top-view of the car; Something like the one shown at NVIDIA CES 2015:


Are there any samples or hints for doing this?

Thanks

Dear francesco.ricciardi,

Maybe you can find GUI Calibration tool and CLI Calibration tool in DriveWorks Tools. Thanks.

We already calibrated,
But I don’t know how to achive a live top view reconstrucion of the 4 cameras.
The only sample that use that calibration is the structure from motion that doesn’t build an unique camera view.
Any advice on how to do this?
