Abstract In this paper we propose a solution to ensure the aircraft safety by using of the technical vision system of aircraft. On board the aircraft mounted only one video sensor, which is source of image. To improve aircraft safety should be reduced situational uncertainty surrounding the aircraft. In the scientific and technical point of view to avoid collisions are required development of technical means for environment monitoring. The technology of image analysis allows automati- cally detect dangerous situations and avoid collisions. For the aircrafts the approach to other airplanes and birds, the approach to the surface of the earth, high buildings and power lines are dangerous situations. To improve safety through effective use of other aircraft systems this technology provides identification of air and ground objects and visual cues. Based on the analysis of the surrounding space around an aircraft is decided there is danger of collision, selected the most dangerous situation and predicted time to collision. Board vision system can warn the crew of the occurrence of a risk of collision, and give the location of important landmarks: the runway, control tower, power lines or completely control their environments and the movement of aircraft, such for driving on the optimal flight path. Detection and identification of ground objects and visual landmarks is made by comparing the video sensor data installed on board the aircraft, with the data of a digital elevation model and digital models of objects corresponding to the current navigation parameters. A detection of the power line on the images is made by using a modified Radon transform. To avoid collisions are necessary automatically detect aircrafts in the image sequence. The algorithm works in real time and effectively detect aerial objects in the image sequence even when the sizes of objects change rapidly, for example, when approaching. Detection of air objects occurs in several stages. The first step is a preliminary detection of candidate objects. The next stage is the confirmation of previous results and restore the object"s shape. To identify air objects are calculated handle external outline, by which is determined the aircraft class.
