Project Aim
The goal of this project is to develop reliable visual motion estimation techniques to be utilized in the control of low altitude manoeuvres for autonomous small-scale aircraft. We are committed to focus our attention on recovering relative altitude of an aircraft by using the terrain texture seen from an onboard camera. We aim to develop techniques that would work reliably on almost any terrain under different weather conditions and to provide evaluation techniques capable of verifying optic flow estimates.
