ABSTRACT:
A method and apparatus compare a star to be identified within an image with data in a database generated from known star data. According to a first aspect of the invention, a target star to be identified within an image is selected, and a number of adjacent stars, normally two, are also selected. The separation values between the stars and a geometric identity for each separation value are determined. This data is compared with corresponding data stored in a database for known stars, where the data in the database is generated using the same technique. According to a second aspect of the invention, a target star is selected, and adjacent stars are selected from an annulus centered on the target star. The separation values for the stars are determined and compared with known separation values stored in a database, where the data in the database is generated using the same annulus centered on each known target star.
