Re: ADSpinnaker::grabImage error GetImageStatus

Hi Mrinal,

You are running the camera very close to the limit of 1 Gbit Ethernet.  The camera dimensions are 2048x1536, and you are using Mono16 mode, so 2 bytes/pixel.  At 16 frames/s that is 96 MB/s.  Other traffic on that network could cause an occasional lost frame.

The camera ADC is only 12 bits.  Does the camera have a Mono12Packed mode?  If you use that you can get 16-bit data with 25% less network bandwidth.  Or 8-bit mode may be sufficient for your application.

Hi Mark,

Even after executing the commands to increase the net.core.rmem_max and net.core.rmem_default to 8MB, I saw the same error message. Attached is the image of the medm screen for the camera after I increased the memory variables. I saw the error message twice so far and in the medm screen I see that the Images Complete in the Collect tab are 2 less than the Started and Delivered frames in the Status tab. 

Thanks,

Mrinal

Hi Mrinal,

Have you changed the Linux buffer settings as documented here:

https://areadetector.github.io/areaDetector/ADGenICam/ADGenICam.html#linux-usb-and-gige-system-settings

Is there more than 1 camera running on this machine?  Can you send a screenshot of the camera screen under the conditions where it is happening.

Mark

Hi Mark,

While using the FLIR camera with ADSpinnaker, I am getting this error intermittently and after sometime the camera stops acquisition. 

2024/12/13 09:48:01.083 ADSpinnaker::grabImage error GetImageStatus  3, description:  Image has missing packets. Potential fixes include enabling jumbo packets and adjusting packet size/delay. For more information see https://www.flir.com/support-center/iis/machine-vision/application-note/troubleshooting-image-consistency-errors/

Do you know how I can fix this?

Best regards,

Mrinal
