Image Acquisition Control
Basler pilot 103
find that your exposure time is the most restrictive factor on the frame rate. In this case, you
should lower your exposure time. (You may need to compensate for a lower exposure time by
using a brighter light source or increasing the opening of your lens aperture.)
The frame transmission time will not normally be a restricting factor. But if you are using
multiple cameras and you have set a small packet size or a large inter-packet delay, you may
find that the transmission time is restricting the maximum allowed rate. In this case, you could
increase the packet size or decrease the inter-packet delay. If you are using several cameras
connected to the host PC via a network switch, you could also use a multiport network adapter
in the PC instead of a switch. This would allow you to increase the Ethernet bandwidth
assigned to the camera and thus decrease the transmission time.
For more information about AOI settings, see Section 11.6 on page 163.
For more information on the settings that determine the bandwidth assigned to the camera, see
Section 5.2 on page 50.
Formula 1:
Calculates the maximum frame rate based on the sensor readout time:
Where:
AOI Height = the height of the acquired frames as determined by the AOI settings.
The constants C

and C

depend on the camera model as shown in the table below:
* Note: The maximum frame rate of the piA1900-32gm/gc is limited to 32 fps.
