Delay Using IMAQ Image

[tiho]

Hi

I am using ProGres Speed XT Core 5 camera and its library. I would like to make some image processing with labview therefore I visualize the images by IMQ Image instrument. Unfortunately I have small delay of image transfer. Could you please see my code here.

Best regards

Hi tiho,

What do you mean by small delay? How big is the delay?

If I understand correctly your post, you are doing some processing befor visualizing the data, have you benchmarked  how long does it take the processing itself?

Hi I make image processing before image visualisation because otherwise I could not use IMAQ image functions. I haven't measure the delay till the moment but I think that it is coming from the image processing at the beginning.

Hi,

It is normal to make the visualization after the processing. 

What do you mean you can not use IMAQ vision functions?

Can you point out what driver are you using for acquisition, when I try to open your VI I have some VIs missing.

Have you managed to measure the delay of processing?

Also, what is the acquisition rate from your camera? How many frames per second?

Hi

The driver of the camera don't give me the possibility to use IMAQ create, IMAQ image and all image assistant modules. I have to transform the data of the camera from picture to imaq image. After this transformation the visualization of the camera is delayed a little bit. I have not measured the delay because I don't know how to do it correctly. The camera has 15 fps.

Hi,

You can use the information from this community page that explains how to benchmark a simple code

https://decibel.ni.com/content/docs/DOC-12892

Basically you have to isolate your image processing which are two VIs inside the sequence structure and measure how long it takes.

Also, where can I find the driver you are using it? It will help me understanding what exactly you are trying to do and I can come with suggestions for improving it.
