Road Edge Detection

[medlag]

Hi,

I m new to Labview and I really need your help,

I m trying to detect road edge from an AVI video file, I used vision assistant and straight edge detector, then I converted the script to vi, the problem is when I try to change from an image inputo video input so I can use the "select a video file" control, and also I want to show the output video with the detected edge,The vi is attached


Please help me to understand how to fix this, or give me a vi example

Thank you

Hello,

This question is better suited for our Machine Vision forum.  However, in LabVIEW you should take a look at the examples under Help >> Find Examples.  Search for AVI and observe the Read AVI examples.  I would probably recommend that you put your image processing code into a subVI.  Place it in a while loop with the IMAQ AVI2 Read Frame VI feeding each frame to your edge detection.  In the examples it is not necessary to keep all of the benchmarking code.
