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.
Z [m]
The elevation of the ground plane. To determine the elevation of the camera, add the Z [m]
value and the Height [m] value of the camera.
Azimuth [°]
The orientation of the camera in a counter-clockwise angle starting with 0° in the east (WGS
84) or on the X-axis (Cartesian). If the camera is directed towards the north (WGS 84) or
the Y-axis (Cartesian), the azimuth is 90°.
WGS 84
The WGS 84 coordinate system is a spherical coordinate system description of the world
and used in many standards including GPS.

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.
