Hi, I have a video (in the .avi format). The video (1 hour length- 25 fps) is of a wind turbine with blades rotating. I want to capture the points during the length of video when one of the blade tip is in line with the tower of the turbine.
I understand that this is possible with MATLAB using Computer vision and Image processing toolbox. Can someone guide me better on this?
Also, I just have a standard MATLAB version. Can I get trial versions for doing this problem statement?

You can get help if you post your code and image.
Yes you can get trial versions. Just call or click the sales department.

Just take the profile along one line. There will be two "bumps" in the profile when it's not aligned, and only one when the blade is over the post.

If your camera is stationary, you can use vision.ForegroundDetector to segment out the moving blade. You can then use regionprops or vision.BlobAnalysis to analyze the shape further.
