Spacecraft Target Recognition and Tracking Based on Ellipse Detection

A method for identifying and positioning the spacecraft is designed based on ellipse detection. The ellipse detection algorithm identifies and locates the spacecraft from the first frame in the ellipse's shape. The bounding box's size and position are calculated by the parameters of the outer ellipse and the inner rectangle. The target tracking algorithm uses the size and position information in the first frame to predict the spacecraft's location in the subsequent frames. The experiments show the superiority of the proposed ellipse detection algorithm and the effectiveness of the spacecraft target recognition and tracking method.
