Abstract :
Ternary amplitude-phase filter (TAPF) is proposed here to improve the performance of hybrid optronics scene matching system. We established the system performance evaluation guideline and matching algorithm distortion invariance evaluation guideline by analyzed the influence factors of matching arithmetic. Compared and analyzed several algorithms´ performances by Stat, experiment, and the results show that TAPF preserves the information of image´s phase and amplitude effectively. TAPF can greatly enhance the anti-noise performance of the system and has good adaptability to bad weathers and improve the probability of scene matching.
