Space target tracking method and system based on multi-feature fusion

The invention discloses a space target tracking method and system based on multi-feature fusion, and the method comprises the steps: obtaining a space target motion model according to the orbit motion of a space target; performing space target feature extraction on the single-frame star map to obtain high-order feature information; initializing the trajectory of the space target in combination with the space target motion model and a logic-based trajectory initiation method to obtain an initial suspected trajectory; and constraining the initial suspected trajectory according to the high-order feature information to obtain an initial target trajectory. The system comprises a model construction module, a feature extraction module, an initialization module and a constraint module. By using the method, the overall real-time performance, accuracy and robustness of the algorithm are improved, and the target real track of a shorter frame is realized.
