Figure 4-4 Measured value acquisition
The camera measuring system determines:
• The vertical offset to the camera axis in millimeters
• The distance between camera and reflector
• The skew around the camera axis
Reflector skew is measured in 1/100 degrees. The reliability of the measured data is checked and
corrected using various algorithms.
The following measured values are acquired:
• Deflections of the reflector in the x and y directions
• Rotation angle of the reflector
• Distance between the camera and the reflector
The measured values are updated at a fixed interval of 50 ms (factory default).
The camera alignment is determined using a calibration function. To achieve this, the reflector
is measured in the home position at various distances.
The measuring system is configured using parameters.
Measuring deflection
The camera measuring system detects deflection on two axes.
The absolute measuring accuracy of the camera measuring system depends on the distance
between the camera and the reflector.
