Vision has been giving me nothing but trouble this year. I have tried all three examples and have not been able to get any of them working well if at all. I have created a custom vi to track the tape using the vision assistant and the retro reflective tape. The first part of the vi that processes the live feed works but the part where is calls upon the file to be compared is flawed. The first problem is that it either can’t find the file or can’t pull it up which prevents the file from being compared to the live feed. I must have working vision and am out of ideas on how to get it working.
One of the diagrams contains a path with an “ftp://…” type of URI path. The LabVIEW paths are file paths, relative or absolute. The functions that take paths will not perform an ftp transaction to retrieve the file. So think about where the code will be, put the file nearby, and use a file system path.
I have been working with our mentors to solve this issue still with no solution. So what you are saying is that we should not use ftp at all, and if we cannot do that where are we able to store a picture for reference. Lastly what is a file system path?
The file system path is a path to the disk or flash-ram. For roboRIO, it will be of the form /home/admin/ or something similar.
You can certainly use ftp, but you cannot just use ftp within a path. There are subVIs for connecting and retrieving files, but if I knew what the end-goal was, this may or may not be necessary.
