Example 1
Assume the following conditions:
• Conveyor movement per line capture = 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 that will cause the image
to cross the red line in the sensor first.
Step 1 - Check Table 3-1 and note that for a 1/1 aspect ratio, n must be set to 8.
Step 2 - Calculate the magnification
β
= 0.07 = 1:14.29
(β
is the standard symbol for magnification and is usually expressed as a ratio)
Step 3 - Calculate the line of view of the sensor
L = 419.60 mm
Step 4 - Use the
Optics Recommendation Guide
and the
Makro.xls Spreadsheet
to select an
appropriate lens and to determine the mounting distance for your camera.
Step 5- Make sure that the
Spatial Correction Starting Line
and the
Spatial Correction Delay in
Lines
camera parameters (see Section
) are set correctly. In this example, the
starting line would be set to red and the delay in lines to 8.
