Abstract: A technique is described for referecing images of wide-angle optical systems intended for registration own radiation of the Earth's atmosphere, to geographic coordinates. The technique is based on an automatic procedure for the stars emphasing and identification in the frames and subsequent georeferencing. An example of the technique use for calculating the characteristics of a long-lived meteor trail based on observation data of two spatially separated wide-angle optical systems is shown.

Keywords: geo-referencing, all-sky camera, star identification, atmospheric emission, long-lasting trail.
