Roll angle:
The angle by which the calibration plane is tilted.
The setting can deviate from the horizontal by up to 10 degrees.
Elevation:
The vertical distance from the camera to the ground plane of the captured image – typically the height of the mounted camera above the ground (in meters).
Camera constant:
The camera constant determines the basic settings for calibra- tion. The default value of 1000 is preset and should only be adjusted if the actual camera constant significantly deviates from this preset. The camera constant is used to compensate spherical distortions from the combination of image sensor and lens.
The camera constant is a function of the focal length of the camera's lens and the pixel pitch of the image sensor. It is calculated with the following formula:
Camera constant = focal length [mm]/(pixel pitch [mm] x 4)
