For the three used cameras the following data are known:

1 1392 × 1040 8 11581440 50 32 ≈ 11.6
2 776 × 582 8 3613056 15.5 32 ≈ 3.6
3 656 × 494 8 2592512 11 32 ≈ 2.6
▪ The sensor resolution and the readout time (t
readout
) can be found in the respective
Technical Data Sheet (TDS). For the example a full frame resolution is used.
▪ The exposure time (t
exposure
) is manually set to 15 ms.
▪ The resulting data volume is calculated as follows:
Resulting Data Volume = horizontal Pixels × vertical Pixels × Pixel Depth
▪ The transfer time (t
transfer10GigE
) is calculated as follows:
Transfer Time = Resulting Data Volume / (1000 × 1000) [ms]
All the cameras are triggered simultaniously.
The transmission delay is realized as a counter, that is started immediately after the sen-
sor readout is started.

* Due to technical issues
the data transfer of
camera 1 does not take
place with full speed.
