For computer vision-based landing of unmanned aerial vehicle(UAV)
it is possible to obtain landing parameters by equations of horizon and edges of runway.A method of horizon and edges of runway detection by using computer vision and image processing technology is studied.Original image are processed by Canny operator to obtain edge information.A new method of line detection is presented
and the horizon and edges of runway is determined by angle between detected line and horizontal axis of image pixel coordinate system.Experimental research shows that this method can detect horizon and edges of runway effectively at different heights and different illumination condition in landing of UAV.
