	ABSTRACT 	   = {

There are many applications in the field of computer vision for a technique that can be used to find a matching set of points in two separate point patterns. One such application is the automatic telescope, where the telescope image can be compared to a finder chart in order to acquire or track a particular star. The problem of matching the CCD image from a telescope with a star finder chart reduces to that of matching two point patterns. With this in mind a new point pattern matching technique has been developed. In order to develop a technique which was rotation, scale and translation invariant, features were extracted from the point patterns which are independent of orientation, scale and position. This paper describes this new technique for point pattern matching and shows how the technique will be applied to an automatic photoelectric telescope which is currently under development at the South African Astronomical Observatory. } }
