I'm currently working on a graduation project about photogrammetric computations of the stereo images. I just got two overlapped images which sees the same object and overlapping ratio is nearly %60-65.I also have some known object points in world coordinates .I'm trying to find world coordinates of the object from the images.The steps I did as the following;
1.calibrating camera by using planar object
2.Matching features of the images and extracting key points
3.determining of fundamental and essential matrix
4.decomposing the essential matrix to R and T elements by recoverPose()
5.creating model coordinates by using image coordinates(points are transformed pixel to image coordinates)
I have one more step named absolute orientation.I couldn't find any function or source to do it.Is there any one knows how to do it ? Thank you for your time.
