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
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 [°] / Roll 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
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.
Calibrating cameras using the Sketch Calibration window
To determine non-automatically set values:
1.
Enter the value for tilt angle, roll angle, height and focal length if the value is known, for
example, by measuring the height of the camera above the ground, or reading the focal
length from the lens.
2.
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.
