Draft
Sensor Perpendicularity
The sensor lines in the camera must be perpendicular to the conveyor’s line of travel. If the sensor
lines are not perpendicular to the line of travel, a slightly different area of the object will fall on each
line as shown in Figure 3-16. This situation will cause haloing that is perpendicular to the transport
direction. The halos will be constant in size. The color of the halo visible on one side of the
elements in the captured image will be different from the color of the halo on the other side. For
example, lettering in the captured image may show green colored halos on the left side of each
letter and violet colored haloes to the right side of each letter.
