Real time imaging using mutiple CCD images

[gistguy]

Hi, I have some trouble with real-time imaging using Labview 8.5.

In present, my goal is imaging with my system based interferometer at high speed rate.

My CCD rate is 200 Hz (maximum) and imaging rate using MAX or grabbing vi. is same as 200 Hz.

But, what I want is to get an image from calculation of multiple captured images taken by CCD camea.

For instance, when one image is acquired from four-intesnity images by the CCD camera, maximum imaging rate is 50 Hz assuming no delay related to program operation.

Opteration speed of my Labview program may lag behind the camera frame rate. Best my acknowlegement, because for loop for taking 4 continous image and images calculation part in while loop is main factor to delay the imaing time. That

Hi gistguy,

I'm having a little difficulty understanding exactly what you are trying to do.  As I understand it, you want to acquire 4 sequential images from your camera, then perform processing on all of the images together.  Is this correct?

If this is the case, you should use 4 IMAQ Create VIs to create 4 different image buffers, then set up your acquisition to acquire an image and cycle between the buffers.  After every fourth acquisition, you can then read all of the buffers and perform the processing.

I hope this helps. Please let me know if this did not answer your question.  Thanks.
