RE: Inconsistency of image rate in ADVimba

Hi Jong Woo,

 

Ø  When I set the Frame rate to be 10 and ROI to be 2464x2056 (full image size), The image rate is sometimes 22 or 2 or 8. There is also no tendency with ROI. The camera is Mako

 

You need to provide some more information.

-          What operating system are you using, Linux or Windows?

-          What version of ADGenICam and ADVimba?

-          What is the value of TriggerMode and TriggerSource?

-          Are there any errors on the IOC console?

 

The easiest way to answer these questions is to attach a screen shot.  Here is a screen shot from ADVimba running my Manta G-507C, which is the same size as your Mako (2464 x 2056).  I am running it at the maximum specified frame rate of 21 frames/s.  The frame rate is very constant at 21 frames/s. 

 

 

Here is the output of camonitor on the frame rate PV (ArrayRate_RBV), labeled Image rate” on the screen.

 

corvette:Data/gpd_user/data> camonitor 13VMB1:cam1:ArrayRate_RBV

13VMB1:cam1:ArrayRate_RBV      2020-10-05 15:54:40.274092 21

13VMB1:cam1:ArrayRate_RBV      2020-10-05 15:59:12.274337 2

13VMB1:cam1:ArrayRate_RBV      2020-10-05 15:59:13.274473 0

 

I started camonitor 13 15:54 and the rate was 21.  I stopped the camera at 15:59, almost 5 minutes later, so the rate went to 0.  During those 5 minutes the value was 21, and never changed at all.

 

So this shows that ADVimba can run this camera at its maximum specified frame rate continuously with no variation.

 

If you are not getting this performance then we need to figure out if it is because you have set some PV incorrectly or if there is some other reason.

 

I recommend that you run the latest version of ADVimba, R1-3..  It provides very useful statistics in the upper-right part of this screen.  Note that in my case there are no packet error or frame errors.  It is important to see if you do have packet errors or frame errors.

Hi, 

 

I found that the Image rate (PV:13VMB1:cam1:ArrayRate_RBV) varies randomly. 

When I set the Frame rate to be 10 and ROI to be 2464x2056 (full image size), The image rate is sometimes 22 or 2 or 8. There is also no tendency with ROI. The camera is Mako. Do you have any idea about this issue? 

 

Best,

Jong Woo
