Web12 feb. 2024 · A homography models a perspective transform of plane. So can account e.g. for a back tilted plane. If your object is planar but can do out-of-plane rotations, the you need a homography to model that. If your mode is not planar, then the homography is not the true model. That being said, often it is a sufficient approximation. http://vigir.missouri.edu/~gdesouza/Research/Conference_CDs/IEEE_ICRA_2010/data/papers/1386.pdf lawn mower repair mifflintown pa
