Overview of guidance information extraction for infrared imaging seeker

Accurate guidance information is the premise condition of precision guidance.In this paper, guidance information was classified and summarized firstly according to straight comprehension. Types of guidance information used in usual typical guidance law design were discussed. According to the tracking filtering and tracking guidance results, there was no relationship between guidance information quantity and guidance goal. On the basis of regarding three-dimensional target as point or plane one, the extraction of 6-DOF information (including position and pose) was put forward. The great significance of target pose information in precision guidance was concluded, and the research status of guidance information extraction was summarized. At last, developing research on pose estimation and the relevant guidance technique were suggested.
