Insert 2D arrays into 3D array

[megastar]

My camera is capturing images (2D array of numbers ranging 0 - 255), now how i can Insert some (say 20) 2D arrays into 3D array in different pages ?

I mean 1st 2d array (image)  ----> page 0 of 3D array,

2nd 2D array ----> page 1 of 3D,

3rd 2D array ----> page 2 of 3D and so on......

I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

You also should learn the basics of "autoindexing"...

[moderator1983]

You can keep your code inside a For Loop (While Loop will also do) and use 'Auto-index Enabled' and thats it....

At the output of Loop, LabVIEW will create a 3D data exactly as your requirement.

Thank you, but i cant keep my camera VI in for loop to generate 3D array.

Output array is 2D array.

To get multiple images, you must run your 'Image acquisition' code multiple times and definitely in a loop. In your existing code also you're using a loop (I'm talking about the 'While Loop', inside the 'Case Structure' which is immediately nested within a 'Giant Flat Sequence Structure').

Now if you dont like the idea to keep a while loop, you may also use a 'Functional Global Variable' (so 'Action Engine', whatever you like to call it).

Do you know from the beginning how may images there will be? Are all images the same size?

It will be most memory efficient to allocate the full size 3D array once and keep it in a shift register or DVR, for example. Then simply replace slices with new image data using replace array subset with the index based on the sequence number of the image.

BTW what is DVR...

sounds like 'Digital Video Recorder'......!! but dosen't go well with the discussion...!!
