I want to know the co-ordinates or angle with respect to y axis of the object detected. In my case we are detecting rectangular object placed in side the swimming pool or water. I should get the any of the object and I should make my robot to align and move in that direction. Please advice.

@pradeep_kb check this tutorial though in your case using PCA might be too much overkill and you might be able to do it much simpler. Some hints to search about are findcontours(), boundingbox, boundingbox angle. I think with these you will be able to find quite some descriptive examples.
