Camera Calibration
Camera Calibration
Camera calibration is required in order for the Luxriot VCA engine to classify objects into
different object classes. Once the camera has been calibrated, the engine can infer real-
world object properties such as speed, height and area and classify objects accordingly.

Calibration Page Elements
The following describes the purpose of each element of the calibration page. To get started
calibrating straight away, see the Calibrating a Camera topic.
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 plane. Placed on the ground plane are a number of 3D mimics that represent the
dimensions of a person with the current calibration parameters. The calibration mimics are
used for verifying the size of a person in the scene.
Mouse controls
The calibration parameters can be adjusted as follows:
Click and drag the ground plane to change the tilt angle.
Use the mouse wheel to adjust the camera height.
