Camera - Positioning
The coordinate system allows you to enter the parameters that define the location of the
camera.
For some panoramic cameras you can also select the mounting position (for example, wall,
ceiling or custom).
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
Select the appropriate mounting position of the camera. Options that appear depend on the
type of camera.
– Standard
Select to configure a global calibration of the AUTODOME and MIC cameras. And then,
enter the height of the camera.
Tilt angle and focal length are provided automatically by the camera to complete the
calibration for every potential field of view of the camera. Optionally, set the calibration
manually for prepositions with video analytics assigned.
– Custom
Select to configure the calibration of the DINION and FLEXIDOME cameras. Cameras on
CPP7 and CPP7.3 platform have an integrated 6-axis-gyro sensor to determine the tilt and
roll angle.
– Ceiling
Select to configure the calibration of FLEXIDOME IP panoramic cameras with ceiling
mount. The calibration assistants AutoSet and Sketch are not available.
– Wall
Select to configure the calibration of FLEXIDOME IP panoramic cameras with wall mount.
The calibration assistants AutoSet and Sketch are not available.
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.
The height of the camera must always be entered manually. Whenever possible, roll angle and
tilt angle are provided by the camera itself. The focal length is provided, if the camera has a
built-in lens.
Tilt angle [°]
Enter the tilt angle if the value is not determined by the camera.
The tilt angle describes the angle between the horizontal and the camera.
A tilt angle of 0° means that the camera is mounted parallel to the ground.
A tilt angle of 90° means that the camera is mounted vertically in bird’s eye view perspective.
