Notice!
If the distance to the camera (geolocation) is not relevant, it is enough to determine height
i
and focal length in relation to each other. This allows a simple calibration by marking 2-3
persons ‑ each with a vertical line ‑ and setting their size. 1,80 m (71 in.) for all is sufficient.
Use at least one person in the front and one person in the background of the image for best
results.
Coordinate system
Select the coordinate system and enter the appropriate values in the additional input fields
that appear depending on the coordinate system selected.
The Coordinate system feature describes the position of the camera in a local Cartesian or
the global WGS 84 coordinate system. The camera and the objects tracked by the video
analytics are displayed on a map.
Cartesian
The Cartesian coordinate system describes each point in the space by a combination of the
position on three orthogonal axes X, Y and Z. A right-handed coordinate system is used, where
X and Y span the ground plane and Z describes the elevation of the ground plane.
X [m]
The location of the camera on the ground on the X-axis.
Y [m]
The location of the camera on the ground on the Y-axis.

For each value that is still unknown, select the Calculate check box, then place a
calibration element on the camera image. Use these calibration elements to trace
individual outlines of the displayed environment in the camera image and define the
position and size of these lines and angles.
Click  
to place a vertical line across the image.
A vertical line corresponds to a line that is perpendicular to the ground plane, such
as a door frame, edge of a building or a lamp post.
Click  
to place a line across the ground in the image.
A line on ground corresponds to a line that is on the ground plane, such as a road
marking.
Click  
to place an angle on the ground in the image.
The angle on ground represents an angle lying on the horizontal ground plane, such
as the corner of a carpet or parking bay markings.
Adjust the calibration elements to the situation:
Enter the real size of a line or angle. To do this, select the line or angle, then enter
the size in the corresponding box.
Example: You have placed a line on ground across the lower side of an automobile.
You know that the automobile is 4 m long. Enter 4 m as the length of the line.
Adjust the position or length of a line or angle. To do this, drag the line or angle or
move the end points to the desired position in the camera image.
Remove a line or angle. To do this, select the line or angle, then click the trash can
icon.
Note:
Blue lines indicate calibration elements added by you.
White lines represent the element as it should be positioned on the camera image based
on the current calibration results or the determined calibration data.
