The optoelectronic location system of overall view is considered. This system is a set of six infrared cameras. The main task is cross-linking of images from the neighboring stations of location system and the formation of a panoramic image on the gyrostabilized cube surface. It is necessary to implement the pairwise affixment of stations considered multicomponent system and link them to the coordinate system of aircraft.
The method to affix location stations of overall view system by linking camera (camera with high resolution) and a pair of patterns is developed. Each of the patterns is a flat surface with the emission sources. Coordinates of emission sources in the coordinate system of pattern are known. The linking camera is used to determine orientation relative to one another pattern (the transition matrix between patterns).
The main affixment stages of two stations of optoelectronic location system are described. A gyrostabilized coordinate system is briefly described. Its relation with the coordinate system of the aircraft is shown.
The panoramic image generation algorithm on the faces of the gyrostabilized cube is described. The example of cross linking images from two web cameras with a resolution of 320 x 240 pixels is shown. Field of view of each camera is 55° horizontally and 40° vertically. The area of intersection of camera fields is 30° horizontally. The variants with different numbers of pictures are considered. The evaluation of accuracy stitching images is given.
The developed algorithm can be used even in the absence of crossing fields of view. It is used for an alignment of multicomponent system of overall view on the board of aircraft.
