- Image segmentation to find the object. The method depends on your image (object ,background,etc ), simplest one, might be im2bw().
- regionprops(..., 'Centroid') to get the center Position for the Obj.
- normalized xPosition corresponds to your angle. Eg Object is at 20% of the image xaxis than your angle is 0.2*55° = 11°.
How can I calculate the angle between two points and camera?

I'm beginner in Matlab and I have to do a project that calculates the angle between 2 points. I'll try to describe it: I have a table that in one corner I have a camera. In the same horizontal line I put one object (or a reference point), let's say it is 0 degrees. Now, I put another object somewhere in the middle of the table and I want that Matlab ill calculate the the angle between them like is it 2D. Also if I can and the object is in the view sight of the camera I want that it will calculate the 2 angles. The natural angle of the camera is 55 degrees.
