Abstract

The camera mounted on the satellite two-dimensional tracking platform takes images of the star background, and using the star map recognition method based on triangle matching can eliminate stars and extract non-stellar targets. When the tracking platform is used to track the non-stellar targets and is moving fast, the tracking targets will be lost. To solve this problem, a spatial target tracking method based on stellar background is proposed in this paper. Firstly, the rotation matrix of the camera in the geocentric equatorial inertial coordinate system at the moment of two consecutive image frames is calculated based on triangle matching, and targets of each image frame are extracted. For a certain target, the coordinate position corresponding to the target are calculated based on the transformation of the rotation matrix. And then the motion of the target in the inertial coordinate system is superimposed to derive the predicted coordinate position of the target. Finally, the nearest Euclidean distance from the predicted coordinates is found among the current target points. If the Euclidean distance is less than a certain threshold value, the target tracking is successful. The simulation experiment shows that when the tracking platform is moving fast, the target can be tracked continuously and stably.
