Height [m]
The height describes the vertical distance from the camera to the ground plane of the
captured image. Typically the elevation of the mounted camera above the ground.
Enter the height in meters of the position of the device.
Sketch
The Sketch functionality offers an additional, half-automatic calibration method. This
calibration method allows you to describe the perspective in the camera's field of view by
drawing vertical lines, ground lines, and ground angles in the camera image and entering the
correct size and angle. Use the Sketch functionality if the result of the automatic calibration is
not sufficient.
You can also combine this manual calibration with the values for roll angle, tilt angle, height
and focal length calculated by the camera or entered manually.
Click to improve the automatic calibration. The Sketch-based calibration window is displayed.
VCA Profile
Select the appropriate profile.
Global
Select the Global check box to use the global, overall calibration for all AUTODOME and MIC
cameras.
Alternatively, clear the Global check box to obtain a local calibration and overwrite the global
calibration for the selected profile. To do this, select the VCA profile before.
Notice!
The Sketch functionality is only available for configured and assigned pre-positions.
For AUTODOME and MIC cameras, configure the pre-positions of the camera and assign the
i
pre-positions to one of the available 16 VCA profiles before calibration with Sketch.
Applications are pre-positions of cameras directed towards different ground planes, an
optimized calibration for inclined ground planes or large focal lengths. A local pre-position
calibration does not change the global calibration.
It is also possible to calibrate pre-positions without entering a global calibration.
Calculate
Select the Calculate check box to obtain the roll angle, tilt angle, height and focal length from
the sketched calibration elements - vertical lines, ground lines and angles - you have placed in
the camera.
Clear the Calculate check box to enter a value manually or to refresh to the values provided by
the camera itself.
Tilt angle [°]
Enter the angle manually, or click the refresh icon to obtain values that are provided by any
sensors that the camera may have. As an alternative, select the Calculate check box to get
values based on the calibration elements that are marked on the image.
Height [m]
Enter the height manually, or click the refresh icon to obtain values that are provided by any
sensors that the camera may have. As an alternative, select the Calculate check box to obtain
values based on the calibration elements that are marked on the image.
Focal length [mm]
Enter the focal length manually, or click the refresh icon to obtain values that are provided by
any sensors that the camera may have. As an alternative, select the Calculate check box to
obtain values based on the calibration elements that are marked on the image.
