Mount the surround view cameras on the vehicle.
Do initial calibration of the surround view cameras using calibration mats.
Take snapshots from the 4 surround view cameras when the vehicle is parked or moving on the road.
Good texture on the road/ground will help in better calibration correction (like a zebra crossing, tiled ground, etc).
Create a surround view correction dataset.
Upload the images and initial calibration values for the 4 cameras.
Run calibration.
