Spatial Correction on Color Cameras AW00049313000
144 Basler runner
Example 1
Assume the following conditions:
 Conveyor movement per line acquisition = 0.2 mm
 Desired aspect ratio = 1/1
 Conveyor Width = 350 mm
 Length of Sensor Line = 29.372 mm (2098 pixels/line x 14 µm/pixel)
 With an objective lens in place, the direction of travel of the object will cause the image to
cross the red line in the sensor first.
1. Check Table 10 and note that for a 1/1 aspect ratio, n must be set to 8.
2. Calculate the magnification
( is the standard symbol for magnification and is usually expressed as a ratio)
3. Calculate the line of view of the sensor
4. Select an appropriate lens and to determine the mounting distance for your camera.
(If you need assistance, contact Basler technical support.)
5. Make sure that the Spatial Correction parameter is set correctly. In this example, the parameter
setting would be +8.
6. Acquire lines.
