Anchor point center of the
plane
The entire calibration plane is moved.
One of the lines of the plane
that is horizontal in the start
position
The calibration plane is tilted horizontally; the
tilt angle is changed.
One of the lines of the plane
that is vertical in the start
position
The calibration plane is tilted vertically; the roll
angle is changed.
Anchor point lower corner of
the plane
The perspective of the calibration plane is
distorted.
Anchor point upper corner of
the plane
The calibration plane is rotated.
Anchor point corner of a cube The size of both cubes changes – both cubes
always represent the same size.
Line of a cube The cube can be positioned as desired.
Size [m] Side length of the cubes.
A side length of 2 m corresponds approximately to the
height of a person.
Center Cubes Both cubes are positioned centrally on the calibration
plane.
Tilt angle [°] The angle between the horizontal and the camera.
The flatter the tilt angle is set, the less accurate the
estimate of object sizes will be. Estimates are no longer
possible when you have reached 0°.
