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, bicycles, cars and trucks, and accurately compute their real size and speeds 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.
This parameter is important for Intelligent Tracking. If using Intelligent Tracking, select
Standard.
Standard
VCA Profile
The MIC camera provides the tilt angle and the focal length automatically to complete the
global calibration for every potential field of view of the camera.
Height [m]
The height describes the vertical distance from the camera to the ground plane of the
captured image. Typically the elevation of the mounted camera above the ground.
Enter the height in meters of the position of the camera.
Sketch
The Sketch functionality offers an additional, half-automatic calibration method. This
calibration method allows you to describe the perspective in the camera's field of view by
drawing vertical lines, ground lines, and ground angles in the camera image and entering the
correct size and angle. Use the Sketch functionality if the result of the automatic calibration is
not sufficient.
You can also combine this manual calibration with the values for roll angle, tilt angle, height
and focal length calculated by the camera or entered manually.
Click to improve the automatic calibration. The Sketch-based calibration window is displayed.
VCA Profile
Select the appropriate profile.
Global
Select the Global check box to use the global, overall calibration for all AUTODOME and MIC
cameras.
Alternatively, clear the Global check box to obtain a local calibration and overwrite the global
calibration for the selected profile. To do this, select the VCA profile before.
