Image Acquisition Control
150 Basler scout
Formula 2:
Calculates the maximum frame rate based on the number of packets needed to transmit a captured
frame from the camera to your host PC via the IEEE 1394 bus:
(round the result up to the nearest integer)
Example
Assume that you are using a monochrome scA750-60 camera set for an exposure time of 2000 µs
and for 600 x 400 resolution. Also assume that you have checked the value of the Payload Size
parameter and the Packet Size parameters and found them to be 327100 and 8192 respectively.
Formula 1:
Max. Frames/s = 68.3 frames/s
Formula 2:
Packets per frame = 39.9
(Round the result up to 40.)
Max Frames/s = 200 frames/s
Formula one returns the lowest value. So in this case, the limiting factor is the sum of the exposure
time plus the sensor readout time and the maximum allowed acquisition frame rate would be 68.3
frames per second.
