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.
