Real time top-view

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?


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?
