The Error color field indicates the deviation of the plotted calibration elements from the
perceived actual situation.
– red: significant deviation.
– yellow: minimal deviation.
– green: length of the plotted lines and angles indicate the actual situation.
Once you have clicked Adapt Elements, the field will always be displayed in green.
The tooltip indicates the deviation of the elements you created from the suggested elements.
The smaller this value is, the better the calibration.
Horizon
If the values correspond, areas on the camera image have a colored background:
– blue: This area corresponds to the sky; the bottom line of the blue area represents the
horizon. Objects that are detected in the blue area cannot be filtered correctly by size or
speed.
– yellow: Objects that are smaller than 2 m and are in the area underneath the horizon
cannot be detected as they are too small. If you wish to detect objects in this area, you
must choose a different camera location.
If the camera is installed at a relatively low height in a building, for example, this display is not
required, because the entire area covered by the camera is below the horizon.
Popup Menu
Right-click in the camera image to open the popup menu. The following commands are
available here:
– Cut: Removes the highlighted element.
– Copy: Copies the highlighted element to the clipboard.
– Paste: Reinserts a cut or copied element.
– Clear All: Deletes all elements.
– To Background: The highlighted element is moved to the background of the display. This
allows you to highlight elements that were masked by the element.
– Hide Other Elements: Hides the elements that are not highlighted.
– Display All Elements: Displays elements that had previously been hidden.
– Create Line on Ground: Corresponds to clicking .
– Create Vertical Line: Corresponds to clicking .

Verify
The calibration can be verified by changing the verify mode.
1. Click Verify.
The button changes the labeling to Calibrate.
2. Place elements on the camera image, as described previously.
The dimensions of the element are displayed underneath the buttons as they are
determined by the calibration. These dimensions should correspond to reality, which
means that a line that is 1 m long on the captured image will be displayed as 1 m in
length.
3. Click Calibrate to switch back to calibration mode.
