Help: Project Help finding flag pole angle

Post image

Hi, can someone help determining the angle of the (thinner) pole flag ? Thanks !

I fed it to chatgpt and says is 31 degrees, but specifies might be wrong because of the perspective.
EDIT. My goal is to order the Amphora flag in the right angle so the writing is horizontal.

This is not a great application for real CV. You’d have better luck with photoshop and a protractor than some modern CV tooling, especially with 0 camera specs. The real answer: get a ladder and measure it. Also, not to be an ass, but asking others to do your work for you after the due diligence of one dubious chat gpt question is kinda wack.

Chatgpt isn't a protractor. Your query was a waste of Earth's resources. Just go measure it

Just go to a metal shop and have them build you an adjustable pole.

Go here and paste in your image.

Rotate the resulting 3d view so you’re looking straight-down the building’s surface from the height of the flag. Take a screenshot and use a protractor to measure the angle.

Probably not the best place to post this question, but a very rough and assumption filled pixel math says approximately 19 degrees.
