A generalized Hough transform is used to acquire and track vehicular targets for missile guidance. This is accomplished by recognizing that most vehicles have silhouettes that may be described as a "rounded rectangle". The position and shape of such rounded rectangles is described in terms of 5 parameters (xc, yc, a, b, θ) where xc, yc are the center coordinates, a,b are the major and minor axis and Θ is the orientation. The computation of a five dimensional Hough transform on an image including such a target will produce the five parameters th...
We claim: 1. A method, comprising: acquiring an image of a scene containing a vehicle; performing edge detection on the image to produce a silhouette image; performing a Hough transform with parameters including center coordinates xc, yc, major and minor axes a,b, and orientation Θ on the silhouette image to detect a best fit of a parameterized object to the vehicle; and passing position, size and orientation parameters of the object to a missile tracker. 2. The method of claim 1, wherein the parameterized object is a rounded rectangle. 3. The...
