This information is sufficient to find the object exactly on the trainImage. For that, we can use a function from calib3d module, ie cv.findHomography (). If we pass the set of points from both the images, it will find the perspective transformation of that object.

For instance, one may click the picture of a book from various angles. Below are a few instances that show the diversity of camera angles. Now, we may want to “align” a particular image to the same angle as a reference image.
