6.7 Sensor parameters
The parameter values are stored in the VVS parameter file VVS_Prm.ini.
The default parameter values stored in the VVS parameter file VVS_DefPrm.ini.
Parameter Description Value (typical)
Start Service Service function. 0
Template Width Depends on the width of the calibration template
used.
350 mm
Exposure Time Exposure time. 3 ms
Calibration Pixels - 8333 pixels
Calibration Width Size of the field of view after calibration.
Approximately 350 for breaker cameras and 450
for carcass cameras.
3000 mm
Lens Type The focal length of the camera lens:
● 1 = 24mm
● 2 = 28mm
● 3 = 50mm
● Three lens types are defined by the last digits
of the camera type.
1
Ascending
Threshold
Thresholds for detecting edges. The values
indicate the intensity level to be crossed in order
to detect an edge. Hysteresis is implemented by
the difference between the two values.
120
Descending
Threshold
100
Calibration State If it is 0 the camera must be calibrated. 1
Temperature Sensor temperature. 30 °C
Right/Left Error 3‑digit error code.
First digit indicates the camera calibrating status:
● 1 = not calibrated.
Second digit indicates the camera operating
status:
● 1 = emergency guiding
● 2 = no result
● 3 = standard calibration: OK
● 4 = standard calibration: no edge
● 5 = standard calibration: only one edge
Third digit indicates lighting errors:
● 0 = optimum lighting
● 1 = soiled
● 2 = under-exposed
● 3 = over-exposed
