AbstractIn order to overcome defects with higher sensibility of moving target detection method for traditional star map space on image brightness among star map frames, frame-to-frame registration, imaging mode and others, taking advantages of the stable feature of the topological structure among star points, a moving target detection method in the star map based on the distance matrix was proposed. The method was used to independently detect targets of all frames of star map; then, it was used to establish the distance matrix of star points and to subtract the distance matrix for consecutive frame of the star map; the corresponding distance of moving target varied greatly; taking advantages of the property, the detection on the moving target was completed. As the distance matrix was irrelevant to the imaging condition of the star map but was influenced by the moving target, thus the method had robustness on image brightness among star map frames, shaking of the observation platform, inter-frame mismatch, imaging mode and others. The simulation experiment and the truthful data experiment show that the method can be used to effectively identify spatially moving targets in background fixed stars under the condition of inter-frame mismatch. Comparing with the tradition method, the method in the thesis has lower false alarm rate. 2017, Science Press. All right reserved.
