Positioning

The Positioning feature describes the location of the camera and the perspective in the
camera's field of view.
Perspective information is essential to Video Analytics, as it enables the system to
compensate for the illusory smallness of distant objects.
Only through use of perspective information is it possible to distinguish objects such as
persons and cars, and accurately compute their real size as they move through 3D space.
However, to calculate perspective information accurately, the camera must be directed at a
single, flat horizontal plane. Multiple and inclined planes, hills, stairs can falsify perspective
information and produce incorrect object information such as size and speed.
Mounting position
The mounting position describes the perspective information that is also often called
calibration.
In general, the mounting position is determined by the parameters of the camera such as
height, roll angle, tilt angle, and focal length.
