Applying the Calibration
1. Click Apply to save the calibration for this image.
2. Click Cancel to return to the last saved calibration.
4.7.2 Global Settings
Certain objects can be globally excluded from detection using this tab. The computing power
required can be reduced if objects that are categorically not to trigger an alarm event are not
monitored.
Size Constraint
Here you can specify a minimum and maximum size for all objects that will generate an alarm
event. Objects that are smaller or larger than the specified sizes will be ignored and this will
save computing power as a result.
Initially, the global settings are preset in such a way that no object is excluded.
The values are simultaneously graphically displayed in the camera image by two yellow-framed
squares. Drag one of the blue nodes to adjust the values. Using the mouse, the yellow squares
can be moved in the camera image to cover objects being used for size comparison.
Make sure that the range between the minimum and maximum size is not too small, or
relevant objects may be unintentionally eliminated from alarm generation.
Roll angle [°] The angle by which the calibration plane is tilted.
The setting can deviate from the horizontal by up to 10
degrees.
Elevation [m] The vertical distance from the camera to the ground plane
of the captured image – typically the elevation of the
mounted camera above the ground.
Focal length [mm] This value can be found in the camera calibration.
Sensor size This value can be found in the camera calibration.
Sensor aspect ratio This value can be found in the camera calibration.
Reset All settings are reset to their initial conditions.
