Installing the sensor
The correct position of the vision sensor is essential in order to function properly. There are various
aspects to be considered during installation, which have to be evaluated. The following chart
summarises the main aspects to consider regarding positioning.

Field of view
The dimension of the range acquired by the sensor varies according
to the distance from the target object to be inspected (see Chapt. 3).
For this reason, the sensor should be placed at a distance which
allows it to focus and observe the entire target object to be inspected.
Resolution
On the contrary to the field range dimension concept, the resolution of
the image acquired by the sensor decreases as the distance from the
target object increases. This is because the sensor acquires an
image with 640x480 pixels. Increasing the focus range, decreases the
number of pixels per unit.
The image to the right shows better resolution compared to the one
on the right. The 640 pixels along the horizontal axis are in fact
entirely "dedicated" to writing. In the first image, however, only half of
them define the logo.

can in fact vary, (e.g. the natural light that shines through a window
can vary in intensity throughout the day) and can therefore
compromise the results of repeated control procedures. It is therefore
