Help! imaq rake can't work

[nongnong]

The VI and my object are in the accessory.

Please help me. I'd like to find out all edges, and obtain the line equations.

I opened your vi and it seems to be working fine for the specified ROI, could you be more specific as to what your trying to achieve, also what version of LabVIEW are you using?

I use LabVIEW 7.1. In my case, the "process" of "IMAQ Rake" can't be nornally connected. It said:"You have two or more enumeration data types wired together, but the enumerations are different. The list of items in the enumerations must be exactly the same." I don't know what the matter is.

Where the broken wire is located from the IMAQ rake function, delete it and the enum constant connected.  Right click on the process node of the function and create a constant.

That should solve your problem.  For some reason it did not like your original enum.  If you have any other questions let me know.

Very thanks! The problem is sloved.

Here I have another problem. As shown in the accessory in the first message, the object have 3 edges lines in the vertical. How to find out the edge line?

I try to find all edges from right to left, then extract the second line, but it seems wrong.
