Tilt:

Defines the tilt of the camera.

VFOV:

Defines the vertical field of view of the camera.

Note: A correct value for the camera vertical field of view is important for accurate calibration and classifi-
cation.

Unit:

Used for changing the unit values between

metric

or

imperial

.

6.1.1 Advanced Calibration Parameters

Pan

and

Roll

allow the ground plane to be panned and rolled without affecting the camera calibration

parameters. This can be useful to visualize the calibration setup if the scene has pan or roll with respect
to the camera.

Note: The pan and roll advanced parameters only affect the orientation of the 3D ground plane so that it can
be more conveniently aligned with the video scene, and does not actually affect the calibration parameters.

6.2 Apply

Saves any changes that have been made.

6.3 3D Graphics Overlay

During the calibration process, the features in the video image need to be matched with a 3D graphics
overlay. The 3D graphics overlay consists of a green grid that represents the ground pane. Placed on
the ground plane are a number of 3D mimics (people-shaped figures) that represent the dimensions
of a person with the current calibration parameters.

The mimics are used for verifying the changes you make to the calibration settings and represent a

person 1.8 metres tall. The mimics can be moved around the scene to line up with people or objects
of a known size to aid in the calibration process.

6.4 How to Calibrate a Camera

• Use the mimics to match against people.

Position the mimics on top or near people within the camera scene.

Note: During the calibration process, as you change settings, you may need to reposition the mimics.

• Enter the VFOV (Vertical Field Of View).

Entering the correct vertical field-of-view is important for accurate calibration, the following table shows
pre-calculated values for vertical field-of-view for different sensors. If the table does not contain the
relevant parameters, use the mimics to adjust the settings.
