An UAV (Unmanned Arial Vehicle) outfitted with autonomous control devices shall navigate to predefined positions. By means of cameras and optical flow the position, height above ground, orientation and velocity is determined. Two flow methods, differential technique by Bruce D. Lucas and Takeo Kanade and normalized cross correlation are presented and compared.
