One of the fields of KeyPoint object is 'pt', which is the coordinate of those key point. Its type is Point32f. So you can access you coordinates like this:

Point32f p = keypoints_object[i].pt;

Or like this

float x = keypoints_object[i].pt.x;
float y = keypoints_object[i].pt.y;

See here for more information about fields of KeyPoint.
