The optical axis of platform was analyzed according to the characteristics of two-axis polar coordinate frame platform, an algorithm of optical axis super-hemisphere stabilization was proposed for the two-axis platform with rolling/swing configuration. The algorithm was efficiently optimized using a dynamic programming method. The simulated results prove that the algorithm can achieve the optical axis super-hemisphere stabilization with high accuracy and fast tracking capability. It has a reference value for practical application.
