Projection of Surveillance Camera Field of View onto Aircraft Moving Navigation Map
This paper describes the method of projection and display of surveillance camera field of view onto moving navigation map installed inside the aircraft, or, in case of unmanned craft, onto the map shown on control table on the ground, or in another aircraft. The surveillance camera is installed on stablilized platform with two controlable axes: pitch axis and yaw axis, thus providing five angular degrees of freedom relative to the ground (inertial) coordinate system, namely five independent angles. The camera does not contain any roll angle. This paper describes the method of projection of the camera axis, i.e. projection of the edges of camera angle of view, relative to flat surface of the ground, together with visualization of the surface corresponding to the field of view of the camera. Accuracy testing was performed with standard project software, as well as testing with moving map in real navigation system of the aircraft.
In broader sense, this method may be used as a part of the algorythm for fire control of the weapon inside the gun turret on the aircraft.
