invalid image type imaqdx

Hello,

I hope that someone helps me to find the error in my VI. I am trying to modify the optical flow feature tracking. So Instead of reading the frame from a folder, I want to collect them from the camera recording.

You can find attached the VI.

Thanks for your help.

having older version installed. Can you post a screen shot of the vi ?

Hello,

Your problem is improper image allocation. This will work:

Your code is quite messy... 🙂

Anyway, I had an old example that I modified, maybe you can find it useful (attaching it for Labview 2010).

Run the program, select the keypoints (hold ctrl + left click for multiple). When selecting keypoints, adding them (via the "add" button) and running the main loop with "continue...",  take care that the object of interest does not move (you can reprogram this at your leisure).

Hope this helps.

Best regards,

K
