Exception Occurred node 0x0 of subVI "IVision_HoughLines.vi"

[DarkAcMe]

LabView: An exception occurred within the externel code called by a Call Library Fuction Node. This might have

corrupted LabView's memory.

Vi IVision_Image Processing Example1.vi" was stopped at node 0x0 of subVI "IVision_HoughLines.vi"

anyone know why? here are the files

Hello,

I can see that you added the Hough Line function into the IVision_Image Processing Example1.vi. But the memory storage ref number you passed in is not correct. Please refer to the IVision_FindLines.vi for how to call the hough function. Below is the diagram of the IVision_FindLines.vi.

I think my memory is corrupted too! Look at those eyes!

A very exceptional looking woman.

PS. Irene_he is most likely on the right track, so I have nothing to add. I just couldn't help myself...

Cool down orko

And yes if she doesn't know, who would. She created the whole IVision Toolkit after all!

Thank you Rolf, your words are always encouraging. I wish I could spend more time to improve it, maybe I should. Irene

It continues the error, I connect my DV camera then I create a loop that snap an image from the cam and then it process the image, it's all fine until for some reason it give me the same error. The last StorageRef was 28241664.

why?

Maybe the block size of memory storage is not correct? You use default value by pass in the "0" in create memory storage vi.

Also we couldn't see your whole block diagram in the image.

I found something curious.. When houghlines.vi detects lines without noise there is no error at any time... the program runs perfectly ( picture node0x0_4), but when it finds distortion or noise, it collapse (node0x0_5). Here is my vi, I use the libraries in the same folder as the vi.

Have you tried out using different size of memory storage? The Houghline function seems only work good on images that have obvious lines... Maybe you can also post on OpenCV discussion forum, see if anyone else can help you with the Hough line function.
