Acquisition vidéos Bandes noires

[_Karibou_]

Bonjour,

Je dispose d'une Camera FLIR modéle : A6753SC qui fonctionne en Ethernet.

J'utilise NI-max pour interroger le flux. 

Pour une raison que je ne connais pas quand une fait une acquisition , je visualise des bandes noir. Chose qui n'apparait pas avec l'outil du fabriquant.

Savez-vous d'où cela pourrait venir ? Y'a-t-il des paramètres à modifier pour l'éviter ?

D'avance, merci pour votre aide.

Cordialement

I have seen this before when the ethernet had too much traffic.

Try a dedicated ethernet connection.

Hello,

Thanks to reply.

I have direct connection between the camera and the computer.

If it could be due to bandwidth, I will search how can I increase it and network seting.

I'll give you a feed back....

Hi, check this, especially the last part about black bars. Screenshots are a bit old, but the troubleshooting method should still apply:

Thanks for the link, I Will check

There is something around the Setting "AcquisitionFrameToSkip". When I put 100, I have  less Flow Stream, but no more black stripe. I had set "IncompleteBufferMode" to "Fail", to display error when something wrong appear... 

I will continue To search to understand, to be able to understand what to optimize.....
