I am implementing 6DOF pose estimation of object. First, my implementation run successfully in the case that given target template object is planar structure. But, my algorithm can not track object which is non planar structure since it use homography for pose estimation (Actually, I need not 6 DOF pose but transformed rect ROI from original template ROI when camera is moved)
When we assume that one image with non-planar structure object is given as template image, Is there method that can get transformed ROI of the template when camera is moved?
