#### Verification of camera Setups
The orientation of all three cameras should be all zeros. When the camera is installed, it is required to record a rosbag by driving a straight highway. By the replay of rosbag, the camera orientation should be re-adjusted to have pitch, yaw, and roll angles to be zero degree. When the camera is correctly installed, the horizon should be at the half of image width and not tilted. The vanishing point should be also at the center of the image. Please see the image below for the ideal camera setup.
